Text label on X-Axis not working

160 views

iOS ios SCILabelProviderBase tex label text label

Hi,

I am using SciChart_iOS_SDK_3.0.0.5074 with Swift 5.

I want to show string type on X-axis. I am using below code snippet.

class YearsLabelProvider: SCILabelProviderBase<SCINumericAxis> {

   var xLabels: [String] = ["Test", "Test", "Test", "Test", "Test", "Test", "Test", "Test",     "Test", "Test", "Test", "Test", "Test", "Test"]

   func update(_ axis: ISCIAxisCore!) { }

   override func formatLabel(_ dataValue: ISCIComparable!) -> ISCIString! {
        let index = Int(dataValue.toDouble())
        return NSString(string: index >= 0 && index < xLabels.count ? xLabels[index] : "")
    }

    override func formatCursorLabel(_ dataValue: ISCIComparable!) -> ISCIString! {
        let index = Int(dataValue.toDouble())

        var result: String?

        if (index >= 0 && index < xLabels.count) {
            result = xLabels[index]
        }
        return NSString(string: result!)
    }
}

Application crashes while loading with the following error –

” *** Terminating app due to uncaught exception ‘Initializer not allowed Exception’, reason: ‘Parameterless initializer of Chart.YearsLabelProvider class shouldn’t be used. Please use one of the designated initializers instead'”

Kindly help us resolving this issue since this is a showstopper issue.
I would also like to know about what data SCIXyDataSeries accepts when we are working with strings.

WPF Binding ExportToFile 3D Charts

Hello,

I am trying to export my 3D chart to a file using SciChart3DSurface.ExportToFile. However, I am getting this error:

InvalidOperationException: There was an error reflecting property ‘InputBindings’.

Code behind:

var surface = ResultTestContent.Positional6DOFErrorTestPage.PositionalChart;
surface.ExportToFile($@"C:\temp\ChartTest.jpeg", SciChart.Core.ExportType.Jpeg, true,new Size(800,800));

Binding to DataSeries in XAML

172 views

I’m trying to build an entire chart in XAML but I’m unsure how I would bind to DataSeries.

For example…

<sci:SciChartSurface>

        <sci:SciChartSurface.XAxis>
            <sci:NumericAxis />
        </sci:SciChartSurface.XAxis>

        <sci:SciChartSurface.YAxis>
            <sci:NumericAxis />
        </sci:SciChartSurface.YAxis>

        <sci:SciChartSurface.RenderableSeries>
            <sci:FastImpulseRenderableSeries>

                <sci:FastImpulseRenderableSeries.DataSeries>

                    <!-- Completely made up "DataSeries" XAML tag, but this is the general idea of what I'm wanting to do -->

                    <DataSeries X="0" Y="{Binding Path=MyObject1.Value}" />
                    <DataSeries X="1" Y="{Binding Path=MyObject2.Value}" />
                    <DataSeries X="2" Y="{Binding Path=MyObject3.Value}" />
                    <DataSeries X="3" Y="{Binding Path=MyObject4.Value}" />

                </sci:FastImpulseRenderableSeries.DataSeries>

            </sci:FastImpulseRenderableSeries>
        </sci:SciChartSurface.RenderableSeries>

    </sci:SciChartSurface>

Is it possible to do something along those lines?

If something along those lines were possible I could probably even build out a DataTemplate to just generate the “DataSeries” tags.

Thanks!

Disable Pan effect on long press

iOS pan xamarin.ios

Hi,

i want to disable the pan effect when user long press on chart and allow the user to scroll only in the currently visible range to view the rollover tooltip so that user can see the reading in the current visible range. Once the long press is release, then enable the pan effect again.

Currently when user try to see the reading using rollover tooltip, the whole chart is moving. I have tried removing and adding the zoompanmodifier on long press gesture in ios. But it is not working.

Thank you in advance.

New user, slow load

WPF Slow loading

Hello,

I’m evaluating SciChart v6.1 for a WPF realtime charting application.
So far everything has worked well, except some issues with very slow loading.
On my machine, any app referencing SciChart takes around 5-6 seconds to initialize before the app can continue loading.

Some debugging with dotTrace shows most of the time is spent in the constructor of SciChartSurface calling the Charting2DNativeDllsLoader constructor.

dev machine is Windows 10 Pro x64, core i7, 32GB ram
Visual Studio 2019 Pro
To duplicate create new WPF application, .NET Framework v4.8
In MainWindow constructor add two lines:

SciChartSurface.SetRuntimeLicenseKey("[TRIAL KEY]");
var tmp = new SciChartSurface();

Executing the second line takes around 5-6 seconds.
I have uploaded a sample project that duplicates this issue and dotTrace result.
Let me know if I can provide any other info.

AutoScale and Zoom

WPF zoom AutoScale

We need to be able to set our chart’s Y axis to be 105. When we add new series (realtime plotting) and one of the points has a value over 105 we need the chart to start auto-scaling to match that new Y value. In other words, unless the user manually zooms we always want the chart to self-resize after starting at a fixed 105 on the Y axis.

This might seem like a strange request at first but our application is expecting a real time series to plot points whose X values might go from -10 to +10; however, the Y value could go from anywhere between 0 and 100 (sometimes higher – although that is not a typical expected value). When we are auto-scaling XY values realtime with no minimal limits the series points are effectively zoomed in really close giving the user a feeling of “noise” to a series that technically doesn’t really exist.

I’ve attached a couple images that demonstrate what a typical series looks like for us. Imaging if only a small portion of the series were currently on the chart and we were using auto-scaling.

Although the 2nd images is a noisy series. It’s REALLY exacerbated when the initial series is auto-scaling during the measurement making it look like the 3rd image.

Updating X-Axis Values within XyDataSeries

152 views

Hello,

is there a way to update the X-Axis Values within an XYDataSeries?
What I found was the Update function to update the Y-Values.
https://www.scichart.com/documentation/win/current/webframe.html#SciChart.Charting~SciChart.Charting.Model.DataSeries.XyDataSeries%602~Update.html

But I can’t figure out how to update the X Values of the DataSeries.

The XyzDataSeries3D does support the functionality to update also the X Value.
https://www.scichart.com/documentation/win/current/webframe.html#SciChart.Charting3D~SciChart.Charting3D.Model.XyzDataSeries3D%603~Update.html

But for the NonUniformGridDataSeries3D I can’t figure out how to update any point.

Maybe I am missing something, just let me know.

Best Regards,
Nick

Hi.

I’m software developer in a small company. Recently our company started using Windows domain and my desctop was added to the domain. Today I figured out what my SciChart license which was fine yesterday is not working. I’m observing “Sorry. Your license token appears to be invalid.”

What should I do to fix this?

SeriesAnimation

I’m trying to find some more info on SeriesAnimation. I’m implementing a ScaleAnimation that works when the chart first loads but I’d like for the series to animate each time the series is updated as well.

Is there a good way to do this?

Here’s my XAML for the ScaleAnimation that animates once when the chart loads…

<sci:FastImpulseRenderableSeries.SeriesAnimation>
                    <sci:ScaleAnimation AnimationDelay="0:0:1" Duration="0:0:1" />

Making a 3D Scatter Plot with MVVM

WPF MVVM viewmodel Chart3D

Hello!

I am getting started with SciChart and attempting to use it for a project I’m working on.

I am attempting to make a 3D scatter plot whose data is populated through a ViewModel.

            </s3D:SciChart3DSurface.ChartModifier>
        </s3D:SciChart3DSurface>
    </Grid>
</UserControl>

And below I declare and define my scatter plot in the viewmodel (the scatterSeries is an XyzDataSeries3D set somewhere else) :

    PositionalErrorTestModel.RenderSeries3DViewModels = new ObservableCollection<IRenderableSeries3DViewModel>();
PositionalErrorTestModel.RenderSeries3DViewModels.Add(new ScatterRenderableSeries3DViewModel
            {
                PointMarker = new SpherePointMarker3D { Fill = System.Windows.Media.Color.FromRgb(0x78, 0xC3, 0), Size = 5, Opacity = 1 },
                DataSeries = scatterSeries
            });

The chart appears, but the data does not. Is there something I’m missing? Do I need to explicitly call an update to the chart? Because the page the chart is on and the chart does get loaded before the data is populated.

Please let me know if you need to know anymore information.

Thanks for any help you can provide!

How to make the ChartModifer works in MVVM

WPF ChartModifier MVVM

Hi I tried to bind the ChartModifer to a property in the VM. But though it build successful, and there is no warning or errors when I run the application , but the ChartModifier does not work.

Here is my code

    <sci:SciChartSurface Grid.Row="1" 
                         YAxes="{sci:AxesBinding YAxes}"
                         XAxes="{sci:AxesBinding XAxes}"
                         RenderableSeries="{sci:SeriesBinding RenderableSeries}"
                         Background="{Binding ChartBackBrush}"
                         Foreground="{Binding ChartForeBrush}"
                         ViewportManager="{Binding ViewportManager}"
                         ChartModifier="{Binding ChartModifiers}">
    </sci:SciChartSurface>

In ViewModel, I created all the child for the ChartModifiers. But it does not work.

        ChartModifiers = new ObservableCollection<IChartModifier>();
        //ModifierGroup.ChildModifiers
        ChartModifiers.Add(rubberBandXyZoomModifier);
        ChartModifiers.Add(new ZoomPanModifier()
        {
            ExecuteOn = ExecuteOn.MouseRightButton,
            ClipModeX = SciChart.Charting.ClipMode.None
        });
        ChartModifiers.Add(new ZoomExtentsModifier());
        ChartModifiers.Add(new MouseWheelZoomModifier());
        rolloverModifer = new RolloverModifier()
        {
            ExecuteOn = ExecuteOn.MouseMove,
            ShowTooltipOn = RolloverVisible
        };
        ChartModifiers.Add(rolloverModifer);

        xAxisDrag = new XAxisDragModifier()
        {
            IsEnabled = true,
            ClipModeX = SciChart.Charting.ClipMode.None,
            DragMode = SciChart.Charting.AxisDragModes.Pan
        };
        yAxisDrag = new YAxisDragModifier()
        {
            IsEnabled = true,
            DragMode = SciChart.Charting.AxisDragModes.Pan
        };

        ChartModifiers.Add(xAxisDrag);
        ChartModifiers.Add(yAxisDrag);

            </sci:ModifierGroup>
        </sci:SciChartSurface.ChartModifier>
    </sci:SciChartSurface>

Then in the code – behind , I created the RenderableSeries.

          var lineSeries = new LineRenderableSeriesViewModel()
            {
                Stroke = (Color)ColorConverter.ConvertFromString(chartParameters.SeriesMetaData[column].LineBrush),
                StrokeThickness = 1,
                AntiAliasing = true,
                DataSeries = xyDataSeries,
                YAxisId = ConvertYAxisTitleToId(chartParameters.SeriesMetaData[column].YAxisId),
                XAxisId = AxisBase.DefaultAxisId,
                IsVisible = chartParameters.SeriesMetaData[column].Visibility
            };

            RenderableSeries.Add(lineSeries);

Now I got a reqirement to the background of the tooltip to transparent. I got some examples ,it seems I should change the s:RolloverModifier.TooltipContainerStyle. But I have no idea how to do it in the code-hebind.

Nearly all examples tell me sth like this, everything is done in the xaml.

How to re-sample waveforms data from DataSeries

183 views

WPF c# IXyDataSeries Waveforms SampleRate

Hi,

I display a waveform using Scichart DataSeries (IXyDataSeries), where waveform dots are not evenly spaced.

I want to read back a sample of this waveform (example: last 10 seconds displayed on the screen) from IXyDataSeries.

The goal is to get waveforms dots again into an array, but this time I want them to be evenly spaced (Sample rate between X is the same).

This means propably that new points will be generated/deleted by the IXyDataSeries during the resampling.

Does Scichart provide a way to do that ?

Thanks

Assume multiple charts link to same list of objects, each chart represents a different property(ies) of the same object, xAxil and yAxil for the charts might be different but total number of data points are the same. Is it possible to link up operation in one chart to other charts? In my case I need to present multiple charts, not one charts with multiple series. This is for WPF.

Thanks.

Interactive FFT chart with Harmonic cursor

247 views

Android

Hi, I’m using the trial version for Xamarin. We wish to develop a mobile app which will have charting capabilities similar to our existing desktop application. I’ll provide an example of what we do (3 screenshots attached), can you please tell me if SciChart can do the same?

In #1 you see an FFT chart.
We select a data point by touching the screen.
In #2 you see a vertical blue line over the selected data point, plus 5 equidistant markers to the right.
We click a button to move right.
In #3 you see the 5 markers have moved to the right, the distance between them has increased slightly.

Is this something that SciChart can handle? Easily? With difficulty?
We want to write all the code in the common Xamarin project only (i.e. no iOS or Android specific code).

Thanks very much,
Wayne

Custom PointMarker for 3D depending on PointMetaData

203 views

WPF WPF

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?

WPF RolloverModifier DateTimeAxis interpolation ArgumentOutOfRangeException

Hello SciChart Team,

I was facing a problem lately and would like to know if you can reproduce it or maybe if you have fixed it in the latest version already.

I have created a chart with a X axis using DateTime as format. When I use the RolloverModifier in combination with Interpolation I get an ArgumentOutOfRangeException when moving the cursor to the Y Axis (see attached image).

I have attached the full excetption details as well.

I am looking forward to your feedback.

problem with xiaomi phones when resume chart after pause it

Android pause lineChart mediaplayer

Hi
I have a chart from a sound.
In xiaomi phones when resume chart after pause it, my line chart faces the severe lag.
In other phones my chart work well.
what should I do?
phone is (Xiaomi mi a3)

private void resume() {

    forceRunInPauseMode = true;
    mediaPlayer.seekTo(currentTime);
    mediaPlayer.start();
    completedState = false;
    pauseState = false;
    updateChart();
}



private void updateChart() {
    schedule = scheduledExecutorService.scheduleWithFixedDelay(() -> {
        if (mediaPlayer.isPlaying() || forceRunInPauseMode){
            UpdateSuspender.using(binding.sciChart, mRunnable);
        }
    }, 0, TIME_INTERVAL, TimeUnit.MILLISECONDS);

}

private Runnable mRunnable = new Runnable() {
    @Override
    public void run() {
        forceRunInPauseMode = false;


        currentTime = mediaPlayer.getCurrentPosition();
        currentRange = currentTime * 2;
        getActivity().runOnUiThread(()->binding.tvCurrentDuration.setText(MiliToTimeConverter.milliToTime(currentTime)));

        if (currentRange < 0)
            currentRange = 0;
        else if (currentRange > xDoubleArray.length - 1)
            currentRange = xDoubleArray.length - 1;

        if (!drawed) {

Dynamic data loading

Retrieving z data in a line between two points

I am creating a chart that uses an XML file that holds data in a tabular format (headers and rows) that i covert to a datatable of strings and then try to convert each column/row value to a double to populate an XYDataSeries object. Sometimes the amount of data is very large which can take 10-15 seconds to process, which is not ideal for the application it is used in.

What i would like to do is create placeholder XYDataSeries that have a series name and dynamically create the data and YAxis when the series is selected initially from the legend.

Is this possible? I have tried in the past but have issues with the data being null.

ExportToBitmapSource fails when the size parameter is not null.

I’m trying to export a surface to an image running this simple line of code:

SciChartSurface.ExportToBitmapSource(false, null);

and it works, but the size of exported image is not good enough for me, so I’m trying this line of code:

SciChartSurface.ExportToBitmapSource(false, size);

But that’s what I’m getting:

System.Windows.Markup.XamlParseException: ''No matching constructor found on type 'SciChart.Charting.Model.ChartData.XySeriesInfo'. You can use the Arguments or FactoryMethod directives to construct this type.' Line number '1' and line position '1884'.'

I would appreciate any help,

Example "MultiPaneStockCharts" does not accept TextFormatting setting

I want to modify the format of XAxis Label of example “MultiPaneStockCharts”, so I do this:

<s:SciStockChart.XAxisStyle>
                            <Style TargetType="s:CategoryDateTimeAxis">

                                <!--added the format here, but does not work-->
                                <Setter Property="TextFormatting" Value="yyyy-MM-dd"/>

                                <Setter Property="DrawMajorBands" Value="True" />
                                <Setter Property="DrawMinorGridLines" Value="False" />
                                <Setter Property="VisibleRange" Value="{Binding ParentViewModel.XVisibleRange, Mode=TwoWay}" />
                                <Setter Property="GrowBy" Value="0, 0.05" />
                            </Style>
                        </s:SciStockChart.XAxisStyle>

But the format of the XAxis labels are not modified as I want it. It seems that something inside the example is preventing format setting, since in different zoom rate the label format is changing.

How can I modify the format?

Thank you.

iOS Simulator Issue

iOS #Rendering black

I was testing my charts on a simulator and when I naved away and then back to the chart screen the Simulator’s chart was totally black screen; I could move the mouse over the points and the popouts would occur; and your license notice showed in the center of the chart. So it was almost like it thought all the drawing for the chart itself needed to be black on black.

It was always broken on the 2nd or later chart. Restarting the app fixed it. I tried removing all custom settings, and calling the invalidate; and nothing caused it to redraw correctly… Fortunately, when deploying to real devices everything worked correctly. Is this an expected side effect of testing on a simulator, or is their something that I can do to force a hard refresh of the chart…

FYI: The additional debug diagnostics don’t seem to do anything on a simulator, or at least I couldn’t find anywhere it was logged.

Force the chart to zoom to a certain starting point

224 views

Android Axis zoom

This might be a stupid question. 😀 But I tried several things and nothing seems to work…

I have a chart that has several different datasets that can be switched to. When I apply them and do zoom to extents it changes the Y Axis sometimes 1-15, sometimes 1-20, sometimes 1-25. So the chart zooms in/out, which looks nice.

However I would like to fix the initial zoom to be always be 1-20. If the chart is smaller or bigger than 20; that is fine; I just want the initial viewport to always zoom to be 1-20, when I switch the dataset. They can then zoom in/out or pan using gestures.

Any ideas on what API I need to call to zoom the chart to 1-20. (Please note, this is using a logarithmic scale on the Y-Axis — if it makes any differences).

So what do I need to call/set rather than calling the zoom to extents function.

First column renders too wide until second column

Android FastColumnRenderableSeries append width

Hi,

I have a fast column renderable series where a column is added each hour. When the first column is added, it renders approximately half the graph (regardless of zoom), which is unintended. Once the data point for the second hour is added, the column collapses down to the space of the hour (as we would want). Why is the first column rendering too wide? Am I failing to set a parameter that is required?

Below is my series setup:

 val uoColumnSeries =
        generateColumnRenderableSeries(LABEL_ID_UO, uoColumnDataSeries, SolidBrushStyle(uoColumnColor))
    uoColumnSeries.dataPointWidth = .95
    uoRenderableSeries.add(uoColumnSeries)

Attached is how the data renders with 1 point (zoomed in and out), and data render once second point (of height 0) is added. The graph in question is the column graph at the top in yellow.

Thanks,
-Andy

How to fix error (VisibleRange was restored to its last valid value)

239 views

Android

This is stackTrace:
E/Axis: VisibleRange was restored to its last valid value. The range class com.scichart.data.model.DoubleRange (Min = 27748.0, Max = 32248.0) either is not valid or it doesn’t satisfy MinimalZoomConstrain or MaximumZoomConstrain. To provide fallback value please override AxisCore#coerceVisibleRange(IRange) method

SciChartOverView does not respect XVisibleRange

WPF SciChartOverview VisibleRange

Hi! I have an overview control, which uses 2-way binding for the x-axis visible range. I actually followed the WPF Realtime Ticking Stock Charts example, the only difference is that I have a line chart with DateRange x-axis. Everything works, except that the overview’s x-axis maximum visible range is not the same as the actual chart’s visible range. Normally the chart is rolling and the maximum x visible range is always ahead of the latest data, just as it’s in the stock chart example. However, the overview’s x visible range always matches the latest x-axis value of the data. So when the overview’s grip is used to scale the x-axis to go back in time, the chart’s x-axis maximum visible range always jumps to match the latest x-axis value of the data and the chart stops rolling. I just don’t get what am I doing wrong or am I missing something? Please see the attached screenshot and the source code. I’m evaluating SciChart to see if it fits our needs before we’d make a purchase and this is something that should work.

Chart Xaml:

<s:SciChartSurface Grid.Row="0" x:Name="Chart" RenderableSeries="{s:SeriesBinding SeriesViewModels}">
            <!--  Create an X Axis  -->

            </s:SciChartSurface.XAxis>

                                ParentSurface="{Binding Source={x:Reference Name=Chart}, Mode=OneWay}"
                                SelectedRange="{Binding XVisibleRange, Mode=TwoWay}"/>
        </Grid>

VerticalSliceModifier with multiple yaxis and Annotations

239 views

WPF multiple YAxis create annotation lively VerticalSliceModifier

Hi,

I’m creating lines chart with data from CSV file.
I have multiple series and each serie has its own YAxis.
As it comes from different CSV files, the number of series and their names are not known in advance.

I create the series in the code (MVVM) .

I’m using the trial version for 2 weeks now and before I purchase the licence, I have two questions:

1) I need to implement a function allowing the user to create multiple VerticalSliceModifier and display data for each serie on the graph and store data to a list or datatable.

Is it possible to have Vertical Slice Tooltip with multiple YAxis ?
If I create a vertical line annotation, can I get data for each serie crossing the line?

2) I need to be able to add annotation dynamically (measure, text, box, lines…).
Is there a way to save annotations to a list (and then to a file) so that if the user reopens the same CSV file he can load and display the corresponding annotations?

Thank you in advance for your answer,
Regards
Nicolas

Prevent Zoom on single left-click of SciChartSurface

255 views

Hello,
On my SciChartSurface, we’re processing real-time data so the chart is always moving. I noticed that when I do a single left-click anywhere on the chart, it changes the ZoomState property from AtExtents to UserZooming.

Is there a way to prevent this?

I was hoping the MinDragSensitivity on the RubberBandXyZoomModifier would handle that but it doesn’t seem to care.

You can reproduce this by using the Drag Area to Zoom example and viewing the ZoomState of the SciChartSurface after you single click on the chart.

What I’m looking for is a way to only change the ZoomState to UserZooming if the MinDragSensitivity has been met.

Thanks in advance.

SciChartOverView resets XVisibleRange

WPF SciChartOverview Scroll Real time zoom and pan

Hello! I have a real time line chart and a SciChartOverview control and the problem is, as soon as I want to extend the visible range with the overview’s slider, the chart’s x visible range is zoomed to extent. I’d like to have the same functionality as in the ScrollChartUsingOverviewControl example and the real time ticking stock chart. In those examples, if the visible range is extended by the overview scroll bar’s left-hand slider, the max visible range keeps rolling with new data, while the min visible range is extended. I followed those examples, by binding the XVisibleRange to the view model in 2 way mode, but for me the max visible range jumps to the latest data as soon as I move the overview’s slider to the left (stops rolling with new data).

Chart xaml:

<s:SciChartSurface Grid.Row="0" x:Name="Chart" RenderableSeries="{s:SeriesBinding SeriesViewModels}">
            <!--  Create an X Axis  -->
            <s:SciChartSurface.XAxis>
                <s:DateTimeAxis AxisTitle="Time" VisibleRange="{Binding XVisibleRange, Mode=TwoWay}" GrowBy="0, 0.1" DrawMinorGridLines="False" DrawMajorBands="True"/>

Duplicate Tooltips for last SCIFastLineRenderableSeries, when tooltipmodifier is added to chart surface before data.

215 views

iOS SciChart TooltipModifier

Originally my chart would
– create the surface
– setup the chart modifiers
– setup the axis
– add the data (SCIFastLineRenderableSeries).

However, it appears that when you .add(new SCIFastLineRenderableSeries) it recreates all the tooltips on each add, and finally on the very last SCIFastLineRenderableSeries that is inserted will get two duplicate tooltips. This happens both with the default tooltips or custom tooltips.

I finally noticed that some of your examples you setup the modifiers at the end after adding the data. So I moved all the chart modifiers into a separate function and called it after the data is setup, and now the proper number of tooltips appears.

This might either need to be noted somewhere prominent in the iOS docs; or even better the order shouldn’t matter.
