Hi!

I want to create a graph, where vertical line annotations are displayed at each column of a chart. I
have the vertical line annotations created like this:

xaml:

code behind

        statisticsChartAnnotations = new AnnotationCollection();
        Style sliceStyle = App.Current.FindResource("sliceStyle") as Style;
        if (displayedChartSeries.Count > 0)
        {
            foreach (DateTime datapoint in displayedChartSeries[0].DataSeries.XValues)
            {
                VerticalLineAnnotation a = new VerticalLineAnnotation()
                {
                    Style = sliceStyle,
                    X1 = datapoint,
                    IsEnabled = false,
                };
                StatisticsChartAnnotations.Add(a);

            }

        }

But when I display the first chart, the annotations are displayed by an offset from the columns. When i switch to the next chart, the annotations jump to the right positions. I attached a picture of the problem. First charts shows the initial positions.

I already tried refreshing the surface through viewportmanager and dataseries. Is this a known bug? is there any workaround? Is there a way to render the annotations right to the data points?

Thanks,
Kristóf

I’m implementing exporting charts. As part of my export, the user can specify the size of the chart. I’ve managed to get sciChartSurface.ExportToBitmapSource() working fine for single graphs.

However, I’ve got some quite complex layouts, and when I try to render parent controls that contain Scichart controls manually, with say:

ExportUIElement.Measure(size);
ExportUIElement.Arrange(new Rect(size));

 int dpiScaling = 3;
RenderTargetBitmap bmp = new RenderTargetBitmap(Width * dpiScaling, Height * dpiScaling,
                                                                                                           96 * dpiScaling, 96 * dpiScaling,
                                                                                                           PixelFormats.Pbgra32);

I’m finding everything working, the chart layout & axis/labels update and render fine, but the chart content is not re-rendered to the new size, causing some messy/strange visual effects. This one was arranged to a larger size, you can see that the actual chart content is now sitting snugly in the middle of a large margin:

enter image description here

Can I force Scichart to re-render these so I can manually render the component in a different size?

Hi,

I’ve been looking through ways to have to y-Axis scale for really small changes/values.

For example, I’m attempting to plot 10 values between 0.99300 to 0.99400, and the changes between points can vary between 0.001 to 0.0001 or so (basically, really small changes)

However, my y-Axis seems to always start at 0 and the y-Axis major ticks are always at most a 0.1 difference, making the graph look flat.

I’d like to achieve the following:
– Scale to the smallest value i can scale to.
– Have my y-Axis to not necessarily start at 0.

I’ve tried the following:

Setting up y-Axis:

    self.yAxis = [SCINumericAxis new];
    [self.yAxis setStyle:axisStyle];
    self.yAxis.axisId = @"yAxis";
    [self.yAxis setGrowBy:[[SCIDoubleRange alloc]initWithMin:SCIGeneric(0) Max:SCIGeneric(0.1)]];
    [self.yAxis setAutoRange:SCIAutoRange_Always];
    [self.chartSurface attachAxis:self.yAxis IsXAxis:NO];

Regards.

Hi
Is there a way to just change the values of the pie segments so it get updated on the donut chart.
If I remove and add the pie segments again it works, is this the correct way?

Also I can’t find any documentation around the donut for android/xamarin

What is the recommended way to use the same text formatting for both Axis and Annotation labels?

There are two scenarios.

  1. When DateTimeAxis automatically change the format

When zooming DatetimeAxis, it automatically changes the text format in the label. For example if XAxis visible range is few seconds, it changes the format as HH:mm:ss. But still the annotation label shows the date. Please see attachement : DatetimeAxisAnnotationLabel.PNG

<sciChart:SciChartSurface.XAxis>
        <sciChart:DateTimeAxis Name="XAxisStartTime" AxisTitle="Start Time"/>
</sciChart:SciChartSurface.XAxis>
  1. When XAxis has got a LabelFormatter

If there is a LabelFormatter, what is the recommended way to apply the same formatting for Annotation Label text?
Please see attachement : LabelFormatterAnnotationLabel.PNG (annotation label shows number of milliseconds)

<sciChart:SciChartSurface.XAxis>
<sciChart:NumericAxis Name="XAxisDuration" AxisTitle="Duration" LabelFormatter="{StaticResource TimeDurationAxisFormatter}" AxisMode="Logarithmic" />
</sciChart:SciChartSurface.XAxis>

Thanks!

When I have cursor tooltips enabled, showing the y-values, they display properly until the y-valuse for the 1st series is below the axis y-min. Below the tooltip y-values are showing correctly
Tootip displaying correctly

If I move the mouse to the left, below 25 Hz, the tooltip disappears as below.
How can I correct this?

Missing tooltip

Hi, guys

I want to show two renderableSeries on one chart view. These series have common x-axis (SCICategoryDateTimeAxis) and separate y-axes(SCINumericAxis). Only one of y-axis is visible at chart view. Also the data series of visible renderable series updated by scrolling to left or to right. So for displaying on one view i’m using:

[y1Axis setGrowBy: [[SCIDoubleRange alloc] initWithMin:SCIGeneric(0.3) Max:SCIGeneric(0.07)]];
[y2Axis setGrowBy: [[SCIDoubleRange alloc] initWithMin:SCIGeneric(0.0) Max:SCIGeneric(5)]];

So it’s look good at start (Correct_zooming.png). But after some scrolling it decrease axis extents of invisible y-axis (decrease.png).
Or even breaks down (broken.png)

For test i’m using SCIFastOhlcRenderableSeries and SCIHorizontallyStackedColumnsCollection readerable series.
Data series for SCIHorizontallyStackedColumnsCollection is initializated like:

    [volumeSerie1 updateAt:index Y:SCIGeneric(100000 / [multiplier doubleValue])];
    [volumeSerie2 updateAt:index Y:SCIGeneric(500000 / [multiplier doubleValue])];

So can you look at it?
Or what way i should implement this behavior?

Best regards,
Sushynski Andrei

Hi

I have experienced some performance issues when accessing YMin & YMax properties of data series containing lots of NaN’s.

I have a chart with the following setup:

XAxis = DateTime / YAxis = Numeric
1 FastLineRenderableSeries series / XyDataSeries<DateTime, double>

I have prefilled the data series with 1 million datapoints. Some of the values are randomly made NaN’s.

If 1/2 of the Y values are NaN’s – accessing YMin or YMax property takes ~117ms.
If 1/10 of the values are NaN’s it “only” takes ~27 ms.
…and if no NaN’s are added to the data series – it takes ~3ms;

This is a huge problem for us – as we have large data series including lots of NaN’s – and we must access the YMin / YMax each time data is added to do special scale fitting. This is normally once per second – but with up to 20 data series – (117ms * 2 *20 ) it takes over 4 seconds.

If I have 10 million datapoints – it takes 10 times as long – so it looks like it is recalculating the min/max each time.

This is what I want it to look like: (see 1.jpg)

This is what (see 2.jpg) it does look like if I leave setIsLabelCullingEnabled enabled (all labels are culled except if I zoom WAY in)
This is what (see 3.jpg) it does look like if I turn off setIsLabelCullingEnabled

I would expect #2 to look like #3 without either one of the 20/15% and either 1% or 1.25% culled, when culling is enabled.

First things the specific values/locations are precise, I need those lines and labels exactly where they are. So I had to create my own LogarithmicNumericTickProvider and feed it all the numbers; this worked great and the numbers are where they need to be — but apparently using our own LogarithmicNumericTickProvider totally breaks culling. Any ideas on how we can get culling to work with our own LogarithmicNumericTickProvider. Is their another way to do this without using our own LogarithmicNumericTickProvider.

Hi

I have come across that Android Scichart consuming a lot of memory while drawing it on the surface. It increase more with the time. When i run the android memory profiler, i find out 60-65 % memory consumed by the Graphics only. The app getting started hangs after some time and become unresponsive. Please let me know how to improve the memory utilization.

Hello again,

I’m working with the 2D Heatmap. I am setting the DrawMajorGridlines to true but they aren’t showing up. I then realized that I could set the Opacity of the series to something different than 1 and the gridlines are shown.

The problem with this is that I want my series background (i.e. all the places where my heatmap has no data double.NaN) to be shown in white, but setting the opacity to something different than 1 makes the background black.

I have tried to set the background to almost anything (Surface, Series, GridLinePanel) and it’s not affecting it.

Am I missing something?

I attach an image.

Thank you.
Kind regards,
Sebastian

Hi guys,

I am having difficulties setting the background of my bar chart with SCICategoryDateTime X axis since I switched to 2.0.

As far as I understand, just setting the background property of the SCIChartSurface should suffice.
These are all of the things I’ve tried:

1. [self.barSurface setBackgroundColor:[UIColor clearColor]];
2. [self.barSurfaceView setBackgroundColor:[UIColor clearColor]]; 
3. self.barSurface.renderableSeriesAreaFill = [[SCISolidBrushStyle alloc] initWithColor:[UIColor clearColor]];
4. [self.barSurface.renderSurface setIsTransparent:YES];

I didn’t find any other way of setting it, but it still remains black. Any thought on what might cause it?

EDIT: I just found out about this color setting:

[axisStyle setGridBandBrush:[[SCISolidBrushStyle alloc] initWithColor:[UIColor whiteColor]]];

The result I got was a black and white chess board, as shown on the attached picture. I really don’t understand this behaviour. If I set this gridBandBrush to nil, columns are coloured with random colours, so the chart looks like a rainbow. I understand why is this happening but shouldn’t there be a default colour in case brush is nil?

EDIT 2: While debugging using “Capture view hierarchy” in XCode I discovered that render surface is actually white inside debugger. Perhaps it will give more insight to you, it doesn’t mean much to me – I guess it’s because rendering is done on GPU and the context is not available to the debugger.

Best,
Igor

I have a situation where I need to have a lot of independent realtime charts rendered on the screen at the same time. I have put a scichart into a user control and that user control into a list so I can reuse my configuration.

Unfortunately, the behavior I am seeing is that when I have more than 5 charts, the charts stutter really badly. I’m using the SciChartPerformanceOverlay to determine what the FPS is of each of the charts.

I can see that in my 5 chart situation, if my mouse cursor is NOT over the window or NOT moving on the window, each chart has an FPS of ~18 for SciChartSurface and an FPS of >500 for Composition Target. When I start to move the mouse around on top of the window, the SciChartSurface FPS value drops to < 5 and the Composition Target drops to ~300.

I’ve got no mouse events hooked up, I’ve set TryApplyDirectXRenderer to true and it seems to accept it. I’ve double-checked the following values:

Direct3D10CompatibilityHelper.HasDirectX10CapableGpu: True
Direct3D10CompatibilityHelper.HasDirectX10RuntimeInstalled: True
Direct3D10CompatibilityHelper.IsSupportedOperatingSystem: True
Direct3D10CompatibilityHelper.SupportsDirectX10: True

I’m suspending the chart before adding points. Each chart only has 1000 points inside a XyDataSeries<int, double> that is databound to a FastLineRenderableSeries. I’m even using Update instead of Append to try to reuse the same memory, in case that makes a difference.

I’ve played with the MaxFrameRate and nothing seems to help.

My dev machine is a bit old and the graphics card is Intel-based, but I never imagined the performance would get so bad so quickly. I’m hoping there’s something I’m missing here as I’ve read such good things about SciChart.

Please let me know if there’s any advice.

Thanks

We have big trouble with SciChart 6.1. First was the initial loading time. But there is this async loading workaround.
Now if we try to render a simple (not large) signal into the chart, it hangs in the rendering loop. No exception, high CPU usage.
Any solution for this issue?
enter image description here

It works on some, but it fails on most of our PCs/Laptops.

Dear Support, I have SciChartSurface in fragment (Xamarin Android). I added Xaxis (DateAxis), Yaxis (NumericAxis), standard modifiers and few XyDataSeries as FastLineRenderableSeries. Everything is working fine (screenshot 1). But something strange is happen when fragment with chart is Paused -> Stopped and then Started -> Resumed. Xaxis and Yaxis are not visible. All dataseries are not visible. But I debugged and all data is there. Even rolloverModifier is still working and correct data values are displayed in labels (screenshot 2). It does not happen every time – it depends on what external intent stopped fragment.

I’ve tried reinitialize chart (clear Xaxis, Yaxis, remove modifiers, remove renderableSeries are reinit all with new variables) and it does not help. Only fragment dettach -> attach helps or screen orientantion change (it reinitializes fragment)

Could you tell me any suggestion what can I check or how to force to redraw whole SciChartSurface? (hiding it and showing it does not help – effect is the same. Only fragment dettach and attach helps (this is my workaround at the moment).

Hi

A couple of months ago I asked if it was possible to plot an XyScatterRenderableSeries (and sometimes a FastLineRenderableSeries) that contained different coloured points – each data point can be in one of many “states”, and the colours are used to indicate these.

I was told it wasn’t possible, so my workaround was to have a separate series for each state, and add each point to the appropriate series based on its state. It’s a bit of a maintenance headache though, as there are often many different states to represent, each requiring its own series.

At the time I was told v2.0 might include support for IPaletteProvider for these series types. The release notes mention FastLineRenderableSeries but not XyScatterRenderableSeries. Did it not make it in?

Regarding FastLIneRenderableSeries, I’m assuming IPaletteProvider only controls the colour of the line and not the point (so it wouldn’t be of use in my scenario)?

Thanks in advance
Andy

What I need is 2 or more VerticalLineAnnotation which can be placed dynamically to act as cursors, showing the difference in value between the two using MVVM and am struggling where to start.

I have been looking at the thread
https://www.scichart.com/questions/question/editing-annotations-and-keeping-track-of-them-in-an-mvvm-application/
but am a bit clueless to what is happening as I am a beginner to C# and MVVM, and am struggling to understand.

I have firstly tried to change your AnnotationMvvm example to use an observable collection as suggested , so that values can be changes, but I can’t even get this to work, as LabelsSource is being returned as null, I am not sure if I have the dependency property correct.I am also not quite sure how the attach etc is working and will struggle to convert to using VerticalLineAnnotation too.

public static readonly DependencyProperty LabelsSourceProperty = DependencyProperty.Register(&quot;LabelsSource&quot;, typeof(ObservableCollection&lt;IChartSeriesViewModel&gt;), typeof(CustomAnnotationChartModifier), new PropertyMetadata(null, OnLabelsSourceChanged));

        // Here LabelsSource is IEnumerable, but you could easily make it ObservableCollection&lt;LabelViewModel&gt; 
        // in order to get changed notifications when items are added to, or removed from the collection
        public ObservableCollection&lt;IChartSeriesViewModel&gt; LabelsSource
        {
            get { return (ObservableCollection&lt;IChartSeriesViewModel&gt;)GetValue(LabelsSourceProperty); }
            set { SetValue(LabelsSourceProperty, value); }
        }

        // Get a notification when new labels are set.
        private static void OnLabelsSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var modifier = (CustomAnnotationChartModifier) d;
            ObservableCollection&lt;IChartSeriesViewModel&gt; newValue = e.NewValue as ObservableCollection&lt;IChartSeriesViewModel&gt;;
            if (newValue == null) return;

modifier.RebuildAnnotations();
}

You say at the end of the thread, you are thinking of doing a good demo on how to do all this, I don’t suppose you could knock me one up using dynamic VerticalLine annotations (MVVM) as above with a display of the difference in the 2 values?

Thanks

I would like to call ThemeManager.SetTheme to change the theme, export an image to file, and then restore the original theme. How can I ensure that the new theme has been applied before calling ExportToFile?

is there a better way to capture a screenshot of a plot using a different theme?

Hi !
Is it possible to display the RollOverModifier tooltip on the real points only ? Say I have points (1 1) and (3 3) in my chart and I don’t wan’t the tooltip to display (1.5 1.5), (2 2), (2.5 2.5) etc. when rolling over… Any idea ?

Thank you,

We have a motion sensor for which we present a real time graph. As can be seen from the attached image, my YAxis configuration (auto range) causes the yaxis scale to display noise in a way that is rather disturbing (see attached image).
I have tried to do some fiddling with the axis settings, but with no luck so far.
The YAxis perfectly follows the measured data, but when there is practically no motion, the graph should be shown as an almost straight line, preferably not in the upper or lower end of the scale.

I’ve implemented the following ContextMenu:

  <s:SciChartSurface.ContextMenu>
            <ContextMenu>
                <MenuItem x:Name ="header1" Header="Einfügen" Command="{Binding InsertItem}" IsEnabled="{Binding SelectedElementsCount,Converter={StaticResource BoolToOppositeBoolConverter}}" />
                <MenuItem Header="Entfernen" Command="{Binding RemoveItem}" />
                <MenuItem x:Name ="header2" Header="Ändern" Command="{Binding ChangeItem}" IsEnabled="{Binding SelectedElementsCount,Converter={StaticResource BoolToOppositeBoolConverter}}" />
                <MenuItem x:Name ="header3" Header="Verschieben" Command="{Binding ChangeItem}" IsEnabled="{Binding SelectedElementsCount}" />
            </ContextMenu>
        </s:SciChartSurface.ContextMenu>

This still worked, but I have changed the AnnotationsCanvas from the Annotations to AboveChart and the Context Menu doesn’t show if I press the right mouse button:

<s:SciChartSurface.Annotations>

            <!-- Draws Bands behind each axis -->

After updating to SciChart 3.1, I started getting the following binding error:

System.Windows.Data Error: 4 : Cannot find source for binding with reference ‘RelativeSource FindAncestor, AncestorType=’Abt.Controls.SciChart.Visuals.SciChartSurfaceBase’, AncestorLevel=’1”. BindingExpression:Path=MaxFrameRate; DataItem=null; target element is ‘HighSpeedRenderSurface’ (Name=”); target property is ‘MaxFramerate’ (type ‘Nullable`1’)

I’m not binding MaxFrameRate anywhere nor do I have a HighSpeedRenderSurface explicitly defined in my code, so I’m guessing this error is occurring somewhere in a SciChart control.

I have several SciChartSurface elements across different controls in my application. I tried setting a global style:

<Style TargetType="{x:Type s:SciChartSurfaceBase}">
    <Setter Property="MaxFrameRate" Value="24"/>
</Style>

This had no effect on the binding error.

Any help would be appreciated since I think these errors are affecting the loading speed of my UI.

Hello Team,

We are going through the Trial version of Sci Chart and we are specifically interested in 2D Scatter Chart and Simple Scatter Chart 3D.

For 2D Chart we tried to bind up-to 1 Million data points and it worked perfectly and we can zoom in 2D Scatter Chart to view each and every point.

When we tried the same for Simple Scatter Chart 3D, it was competitively slower than 2D Chart.

can we do the same in Simple Scatter Chart 3D?

Currently the whole chart is zooming in. Is there a way so that user can zoom in (XAxis , YAxis ,ZAxis ) individually so that each and every point in the chart can be View-able ?

Thanks,

i added the reference “Abt.controls.SciChart.wpf” but always i have the error in the DateTimeAxis.Scrollbar and <s:NumericAxis.Scrollbar> , i think that missing an assembly reference of the scrollbar but i don’t know what’s this assembly (like the errors in the picture)??? thank you !

Hi there,

Following your example “Change Render Series Type” I’d like to know if there is a straightforward way of extending it to include the XyScatterRenderSeries? I’d like to be able to have relatively the same styled appearance when selected and toggled between a FastLineRenderableSeries and an XyScatterRenderableSeries but am uncertain of how this would be accomplished. I apologize in advance if the answer is obvious, I’m quite new to this whole WPF, C#, MVVM thing and any help would be appreciated.

I’ve got error message during compilation:

 ld: bitcode bundle could not be generated because '.../Frameworks/SciChart.framework/SciChart' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build for architecture armv7

I temporary disabled bitcode for target. Will you fix it in the next build?

Hi,
I am using Scichart android ,for Linking Chart Modifiers of Multiple charts I use these lines of code as shown below but it will not synchronize charts on X axis properley sometimes what is the reason ?
Is there is any other method to do that?

ModifierGroup chartModifiers2 = sciChartBuilder.newModifierGroup()
// Setting MotionEventsGroup
.withMotionEventsGroup(“SharedMotionEvents”).withReceiveHandledEvents(true)
.withLegendModifier().withShowCheckBoxes(true).withReceiveHandledEvents(true).build()
.withZoomPanModifier().withClipModeX(ClipMode.ClipAtExtents).withReceiveHandledEvents(true).build()
.withPinchZoomModifier().withReceiveHandledEvents(true).build()
.withZoomExtentsModifier().withReceiveHandledEvents(true).build()
.withRolloverModifier().withReceiveHandledEvents(true).build()
.build();

I getting a weird behavior on my xAxis and yAxis with a real time SciChart.

The labels on axes and the chart itself start shaking like it is trying to update positions but it never gets steady.

I have a background routine adding data to the data series every second and every chart have two series with 2 YAxis, there are only two charts visible in the window at a given time.

Also I have noticed that after a few minutes of doing this the window itself get sluggish and not responsive anymore, I switch to another tab which doesn’t have a chart it start responding again.

Have anyone seeing something like this?

I have tried the Performance Tips and Tricks but nothing changes this behavior.

I’m using a Surface 3 pro with SciChart version 3.3.0.5909

Here is my XAML and the dispatcher timer adding data to the dataseries.

Hi

We are using a simple SciChart setup like the following:

        <Grid Margin="20,45,50,20">

    <!--  Create the chart surface  -->
    <s:SciChartSurface Name="SparseValuesPlot" s:ThemeManager.Theme="Chrome">

        <!--  Declare RenderableSeries  -->
        <s:SciChartSurface.RenderableSeries>
            <s:FastLineRenderableSeries DataSeries="{Binding Values}" Style="{Binding PlotStyle, Converter={StaticResource plotStyleConverter}}" />
        </s:SciChartSurface.RenderableSeries>

        <!--  Create an X Axis  -->
        <s:SciChartSurface.XAxis>
            <s:NumericAxis AxisAlignment="Bottom" GrowBy="0.1, 0.1" AxisTitle="{Binding XAxisTitle}" AutoRange="Never" VisibleRange="{Binding XRange}" />
        </s:SciChartSurface.XAxis>

        <!--  Create a Y Axis  -->
        <s:SciChartSurface.YAxis>
            <s:NumericAxis AxisAlignment="Left" GrowBy="0.1, 0.1" AxisTitle="{Binding YAxisTitle}" AutoRange="Never" VisibleRange="{Binding YRange}" />
        </s:SciChartSurface.YAxis>

    </s:SciChartSurface>
</Grid>

Is there a way to fix the aspect ratio of the chart such that a unit on the x-axis is displayed with the same number of pixels than a unit on the y-axis?

Right now the chart is streched with the surrounding grid. I tried to set height and width of the SciChartSurface but this does not keep the relations because the axis label areas may take different amount of space.

Thanks
Julian

I want to display a point as a decimar separator in numeric values. I have achieved this in chart axis and vertical slices tooltips, creating a custom NumericLabelProvider (see attached picture). How can I do the same with vertical slices xacis labels? (in the picture attached, note that every numeric value has a point as a decimar separator, but vertical slice label has a comma). I have defined LabelTextFormatting of the slice with “#.##E+0”, but it doesn’t work.

Thanks in advance

Regads, Juan

The X axis was set to two axes as follows.

        <s:SciChartSurface.XAxes>
            <s:NumericAxis DrawMajorBands="True"
                           FlipCoordinates="True"
                           GrowBy="0.1, 0.1"
                           Id="Time1" />
            <s:NumericAxis DrawMajorBands="True"
                           FlipCoordinates="True"
                           GrowBy="0.1, 0.1"
                           Id="Time2" />
        </s:SciChartSurface.XAxes>

We wanted to make it selectable with DataPointSelectionModifier for two axes, so we set as follows.

        <s:SciChartSurface.ChartModifier>
            <s:ModifierGroup>
                <s:DataPointSelectionModifier Name="PointMarkersSelectionModifier"
                                              IncludeSeries="False"
                                              IsEnabled="True"
                                              SelectionFill="#B1B5B2B2"
                                              SelectionStroke="#009E9C9C"
                                              XAxisId="Time1" />
                <s:DataPointSelectionModifier Name="PointMarkersSelectionModifier2"
                                              IncludeSeries="False"
                                              IsEnabled="True"
                                              SelectionFill="#B1B5B2B2"
                                              SelectionStroke="#009E9C9C"
                                              XAxisId="Time2" />
                <s:MouseWheelZoomModifier IsEnabled="True" />
                <s:RubberBandXyZoomModifier IsEnabled="False" />
            </s:ModifierGroup>
        </s:SciChartSurface.ChartModifier>

However, only XAxisId = “Time 1” works correctly.

How can we make two axes selectable?

Hi,

I’m trying to use Android’s Magnifier widget on scichart surface but only annotations or crosshairs lines shows and magnify.
Chart series (line, candle etc.) not showing on magnifier window. Is it possible to show all chart surface with series?

Hi,

I’m creating a CustomChartModifier which I am able to hook to a SciStockChart (a template item in a SciChartGroup MVVM) and now I’m having difficulties in adding the BoxAnnotation to the Chart.

This is the code I’m using in my ChartModifier and placing a breakpoint shows me that indeed the code runs through this method, however, I do not see any BoxAnnotation on my chart? I’ve even tried adding the Height and Width properties without any further success. Other CustomModifiers to draw Lines and Ellipses works without problems. Do BoxAnnotations work differently?

I’m looking to have the the user be able to draw a BoxAnnotation on the chart, free hand / dynamically.

SimpleBoxAnnotationModifier.cs

public override void OnModifierMouseDown(ModifierMouseArgs e)
{
        base.OnModifierMouseDown(e);

        var resources = new AnnotationStyles();
        // x:Key="BoxAnnotationStyle" TargetType="s:BoxAnnotation"
        var style = (Style)resources["BoxAnnotationStyle"];

        _annotationCreation = new AnnotationCreationModifier () { AnnotationType = typeof(BoxAnnotation), AnnotationStyle = style };

        this.ModifierSurface.Children.Add(_annotationCreation);
}

AnnotationStyles.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:s="http://schemas.abtsoftware.co.uk/scichart"
                x:Class="ChartModifierBinding.AnnotationStyles">

<Style x:Key="BoxAnnotationStyle" TargetType="s:BoxAnnotation">
    <Setter Property="BorderBrush" Value="#279B27"/>
    <Setter Property="Background" Value="#551964FF"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="IsEditable" Value="True"/>
</Style>

Thanks for any pointers or tips!

Hi,

I would like to implement a Circle / Old style annotation just like how the box annotation works.
I presume one has to override the box annotation to this.

Can you kindly show me how to do this? 🙂

Thanks!

Hi all,

I have another question about SciChart.js, I hope someone can teach me.

First, please download this video

This chart in video is made by d3.js, I hope I can use SciChart.js to make the same features,
please watch from 7 second to the end, when I click the mouse and move to the right direction, then click mouse again,
the section from first click to the second click will make different color, someone can teach me how to do that

PS: English is not my mother language, I wish you all can understand what I mean, Please download the video and watch, thanks.

Hello,

i’ve created the following sample application were i tried to use CategoryDateTimeAxisViewModel as x axis:

class MainViewModel : INotifyPropertyChanged
{
    private IAxisViewModel _xAxis;
    private IAxisViewModel _yAxis;

    public event PropertyChangedEventHandler PropertyChanged;

    public IAxisViewModel XAxis
    {
        get { return _xAxis; }
        set
        {
            if (_xAxis != value)
            {
                _xAxis = value;
                OnPropertyChanged();
            }
        }
    }

    public IAxisViewModel YAxis
    {
        get { return _yAxis; }
        set
        {
            if (_yAxis != value)
            {
                _yAxis = value;
                OnPropertyChanged();
            }
        }
    }

    public MainViewModel()
    {
        XAxis = new CategoryDateTimeAxisViewModel
        {
            AxisTitle = "X-Achse",
            Id = "DefaultAxisId",
            AxisAlignment = AxisAlignment.Bottom,
            AutoRange = AutoRange.Always,
            TickProvider = new DateTimeTickProvider()
        };
        YAxis = new NumericAxisViewModel
        {
            AxisTitle = "Y-Achse",
            Id = "DefaultAxisId",
            AxisAlignment = AxisAlignment.Left,
            AutoRange = AutoRange.Always,
            TickProvider = new NumericTickProvider()
        };
    }

    [NotifyPropertyChangedInvocator]
    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

<Window x:Class="WpfApp1.MainWindow"

    <local:MainViewModel/>
</Window.DataContext>
<DockPanel>
    <s:SciChartSurface DockPanel.Dock="Top"
                       ChartTitle="Testdiagramm"
                       XAxis="{s:AxesBinding XAxis}"
                       YAxis="{s:AxesBinding YAxis}">
    </s:SciChartSurface>
</DockPanel>

When i run the application i can see only the axis titles but no axes, gridlines etc. However when i replace CategoryDateTimeAxisViewModel with DateTimeAxisViewModel everything works fine and looks like expected. What am i doing wrong?

Best regards

I cannot figure out how to setup SciChartSurface so that it would be initialized right away and IsSizeValidForDrawing returned true.

Now I have the special case for the first call to the view with SciChartSurface and I start working with it after receiving SizeChanged event. In this event handler and afterwards IsSizeValidForDrawing gets true and later on all my requests to the view are OK. It’s quite inconvenient.

When does SciChartSurface get resized? What makes it resize?
Which moment does IsSizeValidForDrawing get true?
What should I do to make the size valid after instantiating or receiving first bunch of data ?
How can I make it progmammatically?

This is my xaml:

        <s:SciChartSurface.RenderableSeries>
            <s:FastLineRenderableSeries XAxisId="XAxis1" YAxisId="YAxis1" AntiAliasing="False" />
            <s:FastLineRenderableSeries XAxisId="XAxis2" YAxisId="YAxis2" AntiAliasing="False"  />
            <s:FastLineRenderableSeries XAxisId="XAxis1" YAxisId="YAxis1" AntiAliasing="False" />
            <s:FastLineRenderableSeries XAxisId="XAxis2" YAxisId="YAxis2" AntiAliasing="False" />
            <s:FastLineRenderableSeries XAxisId="XAxis1" YAxisId="YAxis1" AntiAliasing="False"/>
            <s:FastLineRenderableSeries XAxisId="XAxis2" YAxisId="YAxis2" AntiAliasing="False"/>
        </s:SciChartSurface.RenderableSeries>

        <s:SciChartSurface.XAxes>
            <s:NumericAxis Id="XAxis1" />
            <s:NumericAxis Id="XAxis2" />
        </s:SciChartSurface.XAxes>

        <s:SciChartSurface.YAxes>
            <s:NumericAxis Id="YAxis1"  />
            <s:NumericAxis Id="YAxis2" />
        </s:SciChartSurface.YAxes>
    </s:SciChartSurface>

    <Grid Grid.Row="1" x:Name="myOverviews">
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <s:SciChartOverview  Grid.Row="0" 
                    XAxisId="XAxis1"
                    ParentSurface="{Binding ElementName=mySurface}"

                    s:ThemeManager.Theme="BlackSteel">
        </s:SciChartOverview>

        <s:SciChartOverview Grid.Row="1" 
                    XAxisId="XAxis2"
                    ParentSurface="{Binding ElementName=mySurface}"
                    DataSeries="{Binding ElementName=mySurface, Path=RenderableSeries[4].DataSeries}"
                    SelectedRange="{Binding ElementName=mySurface, Path=XAxes[1].VisibleRange, Mode=TwoWay}"

                    s:ThemeManager.Theme="BlackSteel">
        </s:SciChartOverview>
    </Grid>

All visibilities besides SciChartSurface are “Collapsed”

SciChart version 3.1.0.5077

Hi,

I’ve noticed that when I use a custom pointmaker on a renderable series, the preview of the color of that series is missing from the legend of the graph. How can I make it show there? Do I need to update some private property with the “Fill/Stroke” color of the pointmaker?

Good day.

Changing RolloverModifier SourceMode property to AllSeries, AllVisibleSeries and etc. take no effect.
In collection RolloverModifier.SeriesData.SeriesInfo we have only charts, that currently visible in chart field.
Is that bug?

Hello,

I have been working with an application that plots real-time serial data using a FIFO buffer. I have started programming around the ECG-Monitor example as this is exactly what I am creating.

I have a device that broadcasts real-time ECG data via Bluetooth (HC-05), to be exact. I have paired the device and opened a SerialPort in my program to receive the data. My sampling rate is 256 Hz.

When I used a text file to simulate ECG data, it works perfectly well. However, when I use real-time data, there is a delay in charting that increases as the time increases. An easier way to understand this is, the chart continues plotting for a significant period of time even after I have switched off my hardware device.

I have then come to the conclusion that my data is being received at the rate that I want it to, but the plotting gets delayed at an increasing rate as the time increases.

I am currently using the Direct-X rendering type as this gives me a very smooth plot. I receive the data via SerialPort, write to an array and then to the FIFO buffer.

I’m attaching my code for the same.

namespace SciChart.Examples.Examples.SeeFeaturedApplication.ECGMonitor
{
    public class ECGMonitorViewModel : BaseViewModel
    {
    private Timer _timer;
    private IXyDataSeries<double, double> _series0;

        _series0 = new XyDataSeries<double, double>() { FifoCapacity = 2460, AcceptsUnsortedData = true };

        YVisibleRange = new DoubleRange(-20, 500);

I’ve attached pictures of what my program currently does. I have also attached a file with sample data in case anybody wants to test the program. I have also tried building in release mode and that doesn’t help, either.

The only issue is the delay in plotting of real-time data. Otherwise, the graphing and rendering is really smooth. As I am a complete beginner to this, can somebody help with me with what I might have done wrong?

Thanks a ton,

Hello,

I’m having intermitent behavior of column selection when using the DataPointSelectionModifier.

I’m using the PointMetadata API + PaletteProvider to fill the “selected color” of a column when the DataPoint Selection modifier is used.

Sometimes clicking on a column apparently does not trigger the selection changed event.

I have created a sample app with the code I’m using.

I would like to know if this is a bug or I’m doing something wrong.

Thank you.
Sebastian

I recently needed to change the Rotation Angle of a polar plot from the default to 90 degrees. We have line annotations for different points on the polar plot. After the change, the annotation was still plotted on the default Rotation Angle.

I manually updated the points like this for the annotations to work:

var line = new LineAnnotation();

                var x1 = (double)NewSeries.DataSeries.XValues[0];
                var x2 = (double)NewSeries.DataSeries.XValues[1];

                if (x1.Between(0, 90) && x2.Between(0, 90))
                {
                    x1 += 270;
                    x2 += 270;
                }
                else
                {
                    x1 -= 90;
                    x2 -= 90;
                }

                line.X1 = x1;
                line.X2 = x2;

Is there another way to update the annotation or is something like this the preferred way?
