Tag: WPF

Hello,

I am currently working on a proof of concept to move make our software cross platform. Currently, we use the WPF charting package but we have the full bundle so we have access to all the charts. I’m working on a Maui Blazor app where the UI and its logic are stored in a razor class lib and most of the services are stored in the shared WebAssembly project. Ideally, I would like to create the chart data inside a service and then create the appropriate views for each platform using the platform specific charts. Eventually my plan is to have a Blazor WASM project that we host online (where users can view their data), a Maui app that will run on Windows and Mac, and a WPF app that will host the project on computers that aren’t running Windows 10 and 11.

Are there any plans to implement a shared library of some type for the IRenderableSeriesViewModel, IDataSeries, IPaletteProvider, etc. where we could reference these interfaces regardless of platform?

Thank you,

Tim Stephansen

Hi All!

I have a syncfusion theme (MaterialDark) applied to my WPF app.

Without the theme applied, I can set the background color of a TextAnnotaion in the normal way in bothe XAML and c#, no problem.

When I apply the theme, it overrides this setting and renders the TextAnnotation with a black background and no matter what I try, I

can’t seem to get rid of it.

I have tried:

1. setting up a Resource dictionary in XAML

2. setting the style to null and then applying inline style (in both code behind and XAML)

Nothing seems to work!

Has anyone encountered this issue beforew or know of any solutions?

It’s driving me mad!

I want to visualize the octave band.
How can I visualize it?

Hi, I would like to know if it is possible to do half-pie (as in the photo) with SciChartDonutSurface and if so how? Thanks!

Hello all,

I was trying to export my SciChartSurface to bitmap, to save in a pdf.

First I tried ExportToBitmapSource(true/false, wantedSize) method. It leaded to StackOverflowException.
Then I tried to set explicitly the Height and Width and call the parameterless ExportToBitmapSource() method. It works fine, saves fine, but for a second I see the modified Height and Width and axes.
I tried them sync and async calls too.

Have you ever met these kind of functioning, or is the failure in me?

On my SciChart almost everything has predefined Style. Maybe that’s why the ExportToBitmapSource(true/false, wantedSize) dies while cloning the chart inside?

Hello SciChart-Team,
we had the requirement to show the zero line when there are negative values ​​in the chart.
We noticed the following things, especially in connection with the main grid lines.
There are some side effects at certain sizes of the window:
When the gridlines are on(see screenshot 1):
1. Grid line and tick are not on the same level (Only for certain sizes)
2. The grid line and horizontal annotation line (green) are not aligned either (Only at certain sizes)
3. The axis line (defined via BorderThickness) is also not aligned with the grid line (regardless of the size of the control).And the bottom tick is never aligned with the major grid line

If the major grid lines are switched off, the zero annotation line is not aligned to the ticks for certain sizes of the control (see screenshot 2)

It looks like different algorithms were used to calculate the line position of the ticks, grid lines and line annotations.

The problem was detected on the monitor with 100% scaling. On a 4K monitor with scaling > 100%, the problem became even more apparent

Do you have any suggestion how to solve the problem?

I’ve attached a modified example project in which the behavior can be reproduced.

Is there a way to draw an svg formatted annotation onto a chart for WPF?

I have found references/examples for it in javascript here . . .

https://www.scichart.com/documentation/js/current/Tutorial%2006%20-%20Adding%20Annotations.html

but not for any other platform.

Hello SciChart Team,
I have multiple charts in my application where all the charts are in the same MdofierGroup to show the RolloverModifier tooltip at the same time. As I want to show custom tooltip text, I have created a custom TooltipTemplate and TooltipContainerStyle. But now when the tooltip is shown on the left side the tooltip text is a long way from the marker. I want to align the tooltip text based on the tooltip position. When the tooltip is on the right side the text will be aligned left and when the tooltip is on left side the text will be aligned right.

I have attached some code snippets of my implementations, can you suggest me any way to achieve this?

Hi,

I’m trying to evaluate the reality of creating multiple realtime charts and I’m hitting a huge performance brick wall.

My application will have high speed streamed data coming in over ethernet. Currently I’m simulating this with a thread timer that updates 100 data objects at 60Hz. Screen data and chart updates I’ve got throttled to 30Hz but it’s still grinding my charts are still struggling. If I move the mouse pointer the charts freeze entirely until the mouse is still.

I want the end user to be able to choose any data object and chart it however they want. Adding charts and adding plots to charts etc. To enable this I’ve created a chart template as a user control and at runtime the charts are added to a panel on a tab control. Event one chart on one tab chugs though. Move the mouse over it and it locks up.

I have a single overview chart with a scrollbar over the top on the parent control. I need this to control the cursor (vertical line) and shared X visible range. Live data is Fifo limited to a 10 second range. All this works, just painfully slowly.

SharedXVisible range is MVVM bound. Renderable series is LineRenderableSeriesViewModel and data is pushed at 30Hz from a Data provider as per this tutorial:
https://www.scichart.com/documentation/win/current/Tutorial%2006b%20-%20Adding%20Realtime%20Updates%20with%20MVVM.html

CPU usage is sub 20%. Max frame rate is 30fps. Render priority doesn’t seem to make much difference, though “immediate” will lock up the whole app. I’m no expert at performance profiling but I’m not getting any clues from ReShaper dotTrace so far.

I tried creating a version that hand almost no binding and used codebehind to update the data. It didn’t seem to help. I’d rather not do this though as I have a lot of things working that I like such as vertical slice, annotations, templates etc.

I’ve got a list of all the live data on the right of the screen and it all updates rapidly, even while the mouse is moving and the charts are frozen.

I’m also using some Syncfusion controls and theming, if it matters.

I must be missing something obvious surely.

Hello everybody,

I didnt find any answer to this. Is it possible to display data from year 0 to year 9999?

Until now i figuered out, that data from the year 834 to 9166 can be displayed. Beyond this range (eg to 9499) not data were displayed and the x-axis shows todays date.

Thanks for any help
Emanuel

Hi,

I am developing an MVVM WPF application and need to access the SelectedPointMarkers property of DataPointSelectionModifier from the ViewModel.

From looking at the DataPointSelectionModifier documentation (https://www.scichart.com/documentation/win/current/webframe.html#DataPoint%20Selection.html) I can see how you can get the X and Y coordinate values of a selected point in a view, by binding the PointMarkersSelectionModifier to a listbox.

However this doesn’t really help me, I need to get the coordinates of the SelectedPointMarker into a property inside the ViewModel that can be accessed, rather than just binding to a listbox in the view itself.

I’ve also looked at this similar post: (https://www.scichart.com/questions/wpf/i-want-to-bind-selectedpointmarkers-of-datapointselectionmodifier), but I had no luck getting Kenishis solution to work in my case.

How can i do this?

Thanks.

I have a chart with multiple series, and I would like to have the RolloverModifier behavior for all selected series, but with a single tooltip combining the values for all selected series rather than a separate tooltip per series (similar to the CursorModifier)

Is there a way to do one of the following?

1. Merge the tooltips from the RolloverModifier?
   OR
2. Only show the vertical crosshair from the CursorModifier, and snap the crosshair to the closest point in the series?

The RolloverModifier is closer to the behavior I want, the only change I would want is the merged tooltip.

How do you set X1,X2 and Y1,Y2 in xaml as suggested in a previous post here on the forum?

I also get null values here when using Composite Annotations example. the suggestion to set the value DependencyProperty.SetCurrentValue(X1Property, 0.0); does not work since DependencyProperty does not expose a SetCurrentValue method (?)

I am using your example code for doing composite Annotations on my existing chart.
I am using MeasureXAnnotation and MeasureXyAnnotation and the respective Update method that is overidden.

What am I missing ?

Appreciate your help with getting this working

Thanks
Anders

I am having an issue with my Composite Annotation implementation.
I am using the example provided in the MeasureXyAnnotation.xaml that I found here.
My exception that is thrown (see exception attachment provided) complains about a missing Axis value.

In the public override void Update(ICoordinateCalculator xCoordCalc, ICoordinateCalculator yCoordCalc)
the yCoordCalc comes in with a null value. The xCoordCalc is populated and looks valid.

See attachment of my plotting area and well as the chart area. The composite annotation shows up alright, but as soon as I try to drag it the exception is immediately thrown.

I have no idea at this point why. I have tried to implement the annotation according to your example but obviously I am missing something.
Support getting this to work would be immensely appreciated.

Thank you
Anders

Hello guys !
I am looking at the Composite Annotation example provided with the SDK that I downloaded a few days back.

I am somewhat confused on what assemblies I will need . The assemblies list you use is extensive and it is unclear to me what assemblies I need to include to apply this to my plot implementation.

The namespace
SciChart.Examples.Examples.AnnotateAChart.CompositeAnnotations is what I am looking at and what in that list of assemblies will I need to include to successfully implement Composite Annotation in our application ?

I work with a few models and views. Two of them, the ChartView and the PlotView respectively handles the charting surface , then the surrounding toggle buttons and such belongs to the PlotView.

What would be your recommendation how to begin implement this ?

Appreciate the support
Thank you

Cheers
Anders

Hello,

I am trying to set the interval on the x-axis in a polar plot but it doesn’t appear to be accepting it and plotting accordingly. My axis definition is quite simple:

<s:SciChartSurface.XAxis>
       <s:PolarXAxis Name="TFxAxis" MajorDelta="15"/>
</s:SciChartSurface.XAxis>

I am plotting angles and radii so one data point might be (45, 1) and the next (50, 2) and so on where my visible range is TFxAxis.VisibleRange = new DoubleRange(-180.0, 180.0). Very simple plot but it keeps returning to a default of 1 on my MajorDelta for the x-axis and then showing major axes at 50 degree intervals. I’ve tried a variety of solutions but nothing seems to work properly.
Thanks,
Christina

Hey Guys,

On a SciChart surface (CandleStickChart), how could I add LineAnnotation, BoxAnnotation, and TextBox annotation using TradingAnnotationCreationModifierMvvm (available under
ChartAnnotations/Trade Annotations sample). I have recreated a sample, based on the example.

Following is my XAML code,

Chart Surface: Modifiers.

If there is any other way to club all Trading related annotations + TextBox, Line, TrendLine Annotations creation dynamically using any other modiefier, that will do. We are tying to build Trading charts: with Ability to add annotations.

Thanks.

With fifocapacity(XyDataSeries), memory behaves like an image. (Repeat ups and downs)
Is this due to fifocapacity(XyDataSeries)?

Capture : x = minutes , y = MB

Hello,

On our SciChart’s XAxis we are using a NumericAxis and within the NumericAxis we bind to a LabelProvider. In the UI, this works perfectly and we get the XAxis appearing with the titles we desire (as strings writing over the numeric values 0, 1, 2, …). Meanwhile the YAxis doesn’t use any LabelProvider and stays numeric. The XAxis.LabelProvider is an IList of strings.

Although this works great in the UI, when I export the SciChart it does not pick up the LabelProvider and the exported image only contains the numeric values 0, 1, 2, … on the XAxis.

I do the export as following:

SciChartSurfaceBase.ExportToFile(filename, SciChart.Core.ExportType.Png, useXamlRenderSurface, exportedSize);

Is there a way to get the ExportToFile command to acknowledge the LabelProvider is there like it does with the UI?

Thank you!
Hannah

Is it possible to plot a continuous vertical line as part of data point markers in line graph? I have used sprite to render text for data points. Now I want to draw a vertical line starting from data point till the peak apex to show which peak it is pointing to. The text labels in point markers are shifted to upward for some peaks to avoid collision and therefore there is a gap between peak apex and the point marker. So this requirement. I tried so far with OR symbol but it is displayed as a vertical dotted line when multiple OR symbols are placed one below another.

Hi,
Is there a property in XAML to display series name of each FastLineRenderableSeries? TIA

Hi,

I have made the chart vertical by changing X axis alignment to left and Y axis alignment to bottom. After changing like this, im not able to resize the box annotation using all four resize adorners. Only two working, other two resetting Y1 value. below is the code snippet.

<s:SciChartSurface.Annotations>
     <s:BoxAnnotation
         x:Name="rangeBox"
         AnnotationCanvas="AboveChart"
         Background="Red"

         CoordinateMode="RelativeX"
         DragDirections="YDirection"
         IsEditable="True"
         Opacity="0.3"
         ResizeDirections="YDirection"
         X1="{Binding TopDepth, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
         X2="{Binding BottomDepth, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
         Y1="0"
         Y2="1"
         YAxisId="Top" />
 </s:SciChartSurface.Annotations>

     <s:NumericAxis
         AutoRange="Once"
         AxisAlignment="Left"
         AxisTitle="Depth [ft]"
         DrawMajorBands="False"
         FlipCoordinates="{Binding FlipYAxis}"
         TitleStyle="{StaticResource AxisTitleStyle}" />
 </s:SciChartSurface.XAxis>
 <s:SciChartSurface.YAxis>
     <s:NumericAxis
         AxisAlignment="Bottom"

         Id="Top"
         TickTextBrush="DarkGray"

 </s:SciChartSurface.YAxis>

Can you please let me know what i’ve missed?

Hi,

I am using in my chart a VerticalSliceModifer with a VerticalLineAnnotation.
It works as expected, but I would like to modify the aspect of my VerticalLineAnnotation by adding a marker on the axis on top of the line, exactly as in the attached picture (not a scichart).
Is there a way to do that ?

Best regards,
Jean-Charles Durand

Hi,
Is it possible to show contour of bars in ColumnRenderableSeries3D?
Is there way to do this?

ColumnRenderableSeries3D has a Stroke property, but does not appear to have any effect on setting this property.

Hi,

I am currently adding a Vertical Slice Modifier with just on Vertical Line inside of it.
The idea is to create a vertical cursor to display Y values for a given X value.
As my chart is a real time chart, I don’t want my cursor position changed expect on user interaction, I set to Relative the CoordinateMode property of my Annotation.

<s:VerticalSliceModifier Name="sliceModifier" ShowTooltipOn="Always" IsEnabled="True">
                    <s:VerticalSliceModifier.VerticalLines>
                        <s:VerticalLineAnnotation IsEditable="True" X1="0.5" Stroke="#D62D15" CoordinateMode="Relative"/>
                    </s:VerticalSliceModifier.VerticalLines>
                </s:VerticalSliceModifier>

The vertical line is correctly displayed at the centre of the surface but point markers and tooltips are not displayed at the line position, it seems the relative coordinate mode is not handle on this area.

Thanks for your help

Hello,

I want to implement a custom deltaX cursor in my software. It consists in two vertical lines that can be moved be the user and the idea to get the delta x (DateTime) between the two lines.
I’ve started to implement it by using two custom VerticalLineAnnotation added to a VerticalSliceManager. As my chart is a real time chart, I don’t want my cursors postions changed exepct on user interaction, that’s why I set to Relative the CoordinateMode property of my two Annotations.
The display and the interaction works fine, but when I try to retrieve the actual position of one cursor to compute the delta I have some trouble to convert the relative position to a DateTime value.
I have override the OnDragDelta() method, the relative value of X1 is correct but when I try to convert it into a DateTime by using FromRelativeCoordinate, I still have Date in 1899. I also try to interpret this as OA Date but I still have wrong date.

Do you have an idea ?
Thanks

 public override void OnDragDelta()
    {
        if (_sciChartSurface.XAxis != null)
        {
            double dataValue = (double)this.FromRelativeCoordinate((double)this.X1, _sciChartSurface.XAxis);
            DateTime classic = new DateTime((long)dataValue);
            DateTime fromOa = DateTime.FromOADate(dataValue);
            Debug.WriteLine("CLASSIC "+ classic);
            Debug.WriteLine("OA "+ fromOa);
        }
    }

On a small PC with only Intel HD Graphics 4600 the DirectX rendering is not supported by SciChart. Thats fine but it should use the fallback render surface.

<s:SciChartSurface 
  RenderPriority ="Low"
  s:VisualXcceleratorEngine.IsEnabled="True"
  s:VisualXcceleratorEngine.FallbackType="{x:Type s:HighQualityRenderSurface}"
  s:VisualXcceleratorEngine.DowngradeWithoutException="True"
  s:VisualXcceleratorEngine.EnableImpossibleMode="True"
  s:PerformanceHelper.EnableExtremeDrawingManager="True"
  s:PerformanceHelper.EnableExtremeResamplers="True"

I got this exception:

    System.Exception: Your GPU is blacklisted for use by the Visual Xccelerator Engine! There are several reasons why a GPU could belong to the blacklist. For example, low computation capabilities of the GPU could cause Timeout Detection and Recovery of Graphics Adapter Drivers by the OS, resulting in crashing the application.

   at System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value)

But it should use HighQualityRenderSurface without any exception.

Hi,
I’m experimenting with the LegendModifier and want to control which RenderableSeries are shown via the “LegendItemTemplate” approach. The idea is to add a specific tagging class to the RenderableSeries.DataSeries.Tag and use the content inside the LegendItemTemplate which I define in the Window.Resouces.

The tagging Class:

public class DataSeriesTag
{
    public string LegendText { get; set; }
    public bool ShowLegend { get; set; }
}

The LegendItemTemplate:
<Window.Resources>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

            <!--<CheckBox Width="16" Margin="5,0,0,0"
                HorizontalAlignment="Left"
                VerticalAlignment="Center"
                IsChecked="{Binding RenderableSeries.IsVisible, Mode=TwoWay}"
                Visibility="{Binding RenderableSeries.DataSeries.Tag.ShowLegend, Converter={dxmvvm:BooleanToVisibilityConverter}}" />-->

            <s:PointMarker Grid.Column="1" Margin="5,0,0,0" Width="40" Height="10" VerticalAlignment="Center" HorizontalAlignment="Center"
              DataContext="{Binding RenderableSeries}"
              DeferredContent="{Binding LegendMarkerTemplate}"
              Visibility="{Binding ShowSeriesMarkers, RelativeSource={RelativeSource AncestorType=s:SciChartLegend}, Converter={dxmvvm:BooleanToVisibilityConverter}}" />

            <TextBlock Margin="5,0,5,0"
     Grid.Column="2"
     HorizontalAlignment="Left"
     Text="{Binding RenderableSeries.DataSeries.Tag.LegendText}" />

        </Grid>
    </DataTemplate>
</Window.Resources>

As long as I declare the SciChartSurface.ChartModifier in XAML, it works perfect.
The proplem raises when I bind the ModifierGroup to a ViewModel Property and try to build the LegendModifier there. How can I assign the LegendItemTemplate in the ViewModel?:

legendModifier = new LegendModifier(){
            ShowLegend = true,
            ShowVisibilityCheckboxes = false,
            LegendItemTemplate = ??????
        };
        TheModifiers.ChildModifiers.Add(legendModifier);

Kind regards
Martin

After installing the SciChart Licensing Wizard (for current user only), the Wizard hangs and does not display anything, which means I cannot activate the my license.

Sorry for the simple question and please point me to the correct place if I have missed this in the docs.

I am just trying to easily bind the DataSeries of a FastLineRenderableSeries as a custom UserControl.

In my MainView I have placed the custom control:

<customUserControls:CustomLineChart x:Name="CustomLineChart1"
                                                    Grid.Column="1"
                                                    Grid.Row="0" />

My CustomLineChart.xaml is:

 <Grid>
    <sci:SciChartSurface x:Name="simpleLineChart">
        <sci:SciChartSurface.RenderableSeries>
            <sci:FastLineRenderableSeries x:Name="lineRenderSeries"
                                          Stroke="Blue"
                                          StrokeThickness="2" >
            </sci:FastLineRenderableSeries>
        </sci:SciChartSurface.RenderableSeries>

        <!--  Create an X Axis with GrowBy  -->
        <sci:SciChartSurface.XAxis>
            <sci:NumericAxis DrawMajorBands="True"
                             GrowBy="0.1, 0.1" />
        </sci:SciChartSurface.XAxis>

        <!--  Create a Y Axis with GrowBy. Optional bands give a cool look and feel for minimal performance impact  -->
        <sci:SciChartSurface.YAxis>
            <sci:NumericAxis DrawMajorBands="True"
                             GrowBy="0.5, 0.5" />
        </sci:SciChartSurface.YAxis>
    </sci:SciChartSurface>

I am trying to figure out how to bind the UserControl lineRenderSeries.DataSeries property in my MainViewModel

So something like this in my MainView.cs:

public partial class MainView : Window
{
    public MainView(MainViewModel vm, IMainFactory mainFactory)
    {
        InitializeComponent();
        DataContext = vm;

        CustomLineChart1.lineRenderSeries.DataSeries = vm.SomeXyDataSeries;
    }
}

Which works if the SomeXyDataSeries is set prior to this object getting created and does not update because it is not bound

Or something like this in my MainView.xaml

<customUserControls:SimpleLineChart x:Name="CoreStrategyPLGraph"
                                                    Grid.Column="1"
                                                    Grid.Row="0" 
                                                    DataSeries="{Binding SomeXyDataSeries}"/>

I have just been having an issue understanding how to properly set up this binding on the UserControl.

Any input/clarification on how to do this would be great!

Thank you,

Hello,

Is there a corresponding Documentation for the 3D Chart like this one for 2D Charts: https://www.scichart.com/example/wpf-chart-example-series-with-metadata/

What I am trying to do is to make some PointMarkers of the ScatterRenderableSeries3DViewModel in the 3D Chart bigger depending on the PointMetadata3D.
For 2D Charts I could accomplish that with the Documentation mentioned above. Now I want to do the same for 3D Charts.

Can someone give me a hint how to do that?
