Hi, I’m struggling to reduce times for loading draw (5,000Series x 5,000points) x 10 charts
which is in Scichart example ‘Load 500Seriesx500points’.

  1. Present, Loading (5,000Series x 5,000points) x 10 charts consumes about 1 minutes.
    How can i load and draw this more faster?

  2. And While in loading, how can i generate and show a Progress bar?

I wanted to experiment with adding a tooltip to the SciChart_ScatterChartPerformanceDemo.

I extended the xaml with

                <s:TooltipModifier />

However, I have noticed that the tooltip doesn’t seem to react properly to the geometry under the cursor. The tooltip will often show up when the cursor is outside the geometry.

If you use a SquarePointMarker with a width and height of 25, the tooltip pops up even when you’re a fair distance away from the geometry.

The hit detection doesn’t appear to be working correctly?

Edit : Also, it appears I am unable to answer questions here, when I add an answer, it accepts it, but doesn’t show anything?

I’m overriding FastLineRenderableSeries so I can do some custom rendering.

I have a data series defined as :

 var xyDataSeries = new XyDataSeries<double>();
            xyDataSeries.Append(0, 0);
            xyDataSeries.Append(1, 1);
Test.DataSeries = xyDataSeries;

and my chart as :

<s:SciChartSurface Loaded="SciChartSurface_Loaded">
            <customSeriesMvvmExample:FastLineRenderableSeriesEx x:Name="Test" />

And then I override InternalDraw :

public class FastLineRenderableSeriesEx : FastLineRenderableSeries
    protected override void InternalDraw(IRenderContext2D renderContext, IRenderPassData renderPassData)
        base.InternalDraw(renderContext, renderPassData);

        using (var brush = renderContext.CreateBrush(Colors.Transparent))
        using (var pen = renderContext.CreatePen(Stroke, true, StrokeThickness, Opacity))

            var xCalc = renderPassData.XCoordinateCalculator;
            var yCalc = renderPassData.YCoordinateCalculator;

            var xCoord = xCalc.GetCoordinate(0.5);
            var yCoord = yCalc.GetCoordinate(0.5);

            renderContext.DrawEllipse(pen, brush, new System.Windows.Point(xCoord, yCoord), 150, 150);

                new System.Windows.Point(xCalc.GetCoordinate(0.6), yCalc.GetCoordinate(0)),
                new System.Windows.Point(xCalc.GetCoordinate(2), yCalc.GetCoordinate(1.4)));

The problem is that the base.InternalDraw draws the original data series line very nicely with anti-aliasing, but the custom circle I draw has no AA, and the custom line I draw looks very thin?

what’s going on here?

I am running the app which uses the sci chart object FreeSurfaceRenderableSeries3D.
This is a 3d spherical surfaced object, i tried to run it in release mode, i am unable to do the manual rotation using mouse drag to explore the surface of the 3d object. But the object is on freeze for any mouse activity on screen.
I have attached sample image of state of my app.
Please suggest.

I am facing the following two issues related to application crash and unable to perform 3d object rotation in release mode.

Issue 1: Application Crash
I am using PointLineRenderableSeries3D object to render the Data series points.
I have a timer which ticks every 1 sec and have new data series points with some rotation of previous values.
Hence will try to add new points on every 1 sec to the same object data series

timer1.tick +=(() => {
// rendererUpdate is object of PointLineRenderableSeries3D

        using (rendererUpdate.DataSeries.SuspendUpdates()) 
              var newData = GetNewPointsWithRotation( rendererUpdate.DataSeries, 30);//30 is angle of rotation for older points
                rendererUpdate.DataSeries = newData;


Issue 2: When i run the application in release mode, i am unable to perform manual rotation using mouse dragging for the 3d sphere FreeSurfaceRenderableSeries3D object SurfaceMesh referred in the code.
When the application is running in release mode , i tried to drag rotate the 3d shape, but the 3d object is not responding to the mouse drag event (Press hold mouse left button and drag).

The attachment contains the wpf code (xaml and cs) in the same file.
Code refers .jpg file, Please refer any local jpg file to repro the issue.

Please suggest the possible reasons and fixes of the same.
Please provide the possible insights of the same.

I want to create a chart like the attached image file.
I want to mark points with different colors depending on the number of data corresponding to the x and y axes.
As a result of searching, there is a HeatmapColorPalette. Is it good to use this?
If there is a more suitable chart, please introduce it.
thank you

Hello all,

our application is recording data points from a measurement device. The recorded data points are shown in a 2D and 3D chart. Both charts are within one page, the user can switch between the charts via TabControl.

The problem we have is, that when a new data point is added, the chart, which is not in focus (so not selected by the TabControl) does not update.
For the 2D chart we could solve this issue by executing the following code on the TabControl selection changed event:

this.ViewportManager.BeginInvoke(() => { this.ViewportManager.ZoomExtents(); });

For the 3D chart we tried the same approach with the following code (also exectue on the TabControl selection changed event), the function ScaleWorldDimensions adjust the 3D space based on the recorded data:

   Application.Current.Dispatcher.Invoke(() =>
            if (this.ListDataPoints.Count > 0)

But unfortunately this does not solve the issue. Therfore the user either has to switch the tab again or add a new data point when the 3D chart is selected.

Do have hints on how to solve this issue?

Thanks for your support in advanced, in case you need furhter information please let me know.

Is there any way to create a multipane chart in WPF like it done using Sub-Charts API in JavaScript chart where it shares same WebGL chart surface.

I know the way it is done using SciChartGroup where there are multiple SciChartSurfaces added to the group in order to create multipane chart, but if it can be done the way it is done in JavaScript charts, it will improve WPF chart performance drastically I think.

When the X-axis mouse scroll to zoom in or out, the use of MouseWheel=”mouseWheelZoomModifier_MouseWheel” monitoring is invalid, how to do the mouse wheel zoom, dynamic loading more data, the mouse wheel shrink, do not need to reduce the data, because in some cases the one-time loading data is too large

I have several simple SciChartSurfaces in my WPF-grid. They are in the same WPF-column but in different WPF-rows, so they are arranged in a vertical manner.

I have noticed that the Y-Axis (a NumericAxis-objcet) moves automatically slightly to the left to make room for the numbers on the Y-Axis, if necessary.

I would like to ask if there is a way to “synchronize” the position of several similar Charts (or their Y-Axis´s, respectively.), so the different Y-Axis´s would always be in the same position. Ideally, the Y-Axis´s of all the Charts would move as far to the left as necessary to make room for the longest number of all the Axis´s.

I have attached an example of my current situation and the solution I would ideally like to achieve.

Is there any way to “connect” the different Axis of the charts to create the desired result?

Thank you.

I was having some issues with 2 of the chart modifiers for a SciChart3DSurface. The FreeLookModifier3D used to work as intended, but now non of the key presses work. However, the “ExecuteOn” middle mouse button does free look the camera, I just can’t move the camera forwards and backwards with the ‘w’ ‘a’ ‘s’ ‘d’ ‘c’ or ‘e’ keys. In short, I figured it was something I did since I’m messing with the keyboard, but I haven’t been able to pin down the problem. Then, the VertexSelectionModifier stopped working as intended. It seems as if it’s successfully attached to the surface, but it fails to select any points. This previously worked, and stopped moving around the time when I moved SQL databases, oddly enough. I’ve uploaded a short video to Google Drive ( that demonstrates that the selection box appears when I hold down the left mouse button. What might be causing the chart modifiers to misbehave.

I’m encountering some odd behaviour when I rescale my graph to modify the range of the X axis. For certain data series, the line disappears from the chart.

e.g. I have a data series that’s 2899 points long, with X values ranging from -6.17 to 22.81, so I change my X axis range to be from -8 to 24 to fit it all in. When I change the VisibleRange of the SciChartSurface.XAxis, then the line disappears. If I don’t rescale the visible range then the portion that would be visible is rendered fine.

The funny thing about it is, if I remove the last point from the series before adding to the chart, it draws fine, even after I rescale the visible range! The same goes for if I add another point to the end (e.g. even if that point is identical to the existing last point).

Now if I hover the mouse (Rollover) over the chart, the spot to highlight the point in the line still appears as if the graph was still there. It’s like it’s there but invisible.

I’ve tried setting DebugWhyDoesntSciChartRender to true, but this fires only when the chart is initially drawn and no series’ have been added yet, so I get

SciChartSurface didn’t render, RendererErrorCode: [RendererErrorCode: [Because the SciChartSurface.RenderableSeries collection is null or empty. Please ensure that you have set some RenderableSeries with RenderableSeries.DataSeries assigned, or you have set Axis.VisibleRange for all axes in order to view a blank chart.]
RendererErrorCode: [Because none of the SciChartSurface.RenderableSeries has a DataSeries assigned]

However I add the DataSeries’ after this, and when I do that, or rescale the axis, no error is reported.

Here is my XAML code to show the chart:

        Annotations="{Binding Annotations}"
        GridLinesPanelStyle="{StaticResource GridLinesPanelStyle}"
        RenderableSeries="{s:SeriesBinding ChartSeries}"

                            <Setter Property="StrokeThickness" Value="16"/>
                            <Setter Property="Opacity" Value=".2"/>
                            <Setter Property="IsHitTestVisible" Value="False"/>

                        <!--  When a series is selected (on click), apply this style  -->
                        <Style TargetType="s:BaseRenderableSeries">
                            <Setter Property="Stroke" Value="DeepPink" />
                            <Setter Property="StrokeThickness" Value="3" />


and here is the code to change the Axis visible range. (In the ViewModel). Note that while this changes both the X Axis and the Y Axis scale, only the X Axis change causes this problem.

        protected override void ScaleAxes(double xaxisLowerValue, double xaxisUpperValue, double yaxisLowerValue, double yaxisUpperValue)
        var xAxisRange = new AxisRange(0, 0);
        var yAxisRange = new AxisRange(0, 0);

        //Resolve time axis
        yAxisRange.MaxValue = CalculateUpperBoundary(yaxisUpperValue, (double)_graphIndicators.BarChartMaxIndicator, YAxis.UpperPadding, YAxis.MajorDelta);
        yAxisRange.MinValue = CalculateLowerBoundary(yaxisLowerValue, (double)_graphIndicators.BarChartMinIndicator, YAxis.LowerPadding, YAxis.MajorDelta);

        //Resolve Volume Axis
        xAxisRange.MaxValue = CalculateUpperBoundary(xaxisUpperValue, xaxisUpperValue, XAxis.UpperPadding, XAxis.MajorDelta);
        xAxisRange.MinValue = CalculateLowerBoundary(xaxisLowerValue, xaxisLowerValue, XAxis.LowerPadding, XAxis.MajorDelta);

        //ensure max and min range have not exceeded the boundary range.
        xAxisRange = EnsureRangeIsWithinBounds(ref xAxisRange, XAxis.BoundingRange);
        yAxisRange = EnsureRangeIsWithinBounds(ref yAxisRange, YAxis.BoundingRange);

        //ensure max and min range are within optimal range.
        xAxisRange = EnsureRangeIsWithinOptimal(ref xAxisRange, XAxis.OptimalRange);
        yAxisRange = EnsureRangeIsWithinOptimal(ref yAxisRange, YAxis.OptimalRange);

        //update the display range
        XAxis.DisplayRange = xAxisRange;
        YAxis.DisplayRange = yAxisRange;

Hi Scichart Team,

I want to add two border lines on the top and left of the chart on the existing theme —“BrightSpark”, I searched and tried some IThemeProvider memebers but have no luck to solve it.

Please find the detail in attached pic, just like bottom and right sides, add two border lines on the other two sides.

Hello Scichart Team,

Can you guys provide me with some guidance to implement a custom IRenderableSeriesViewModel implementation that is supported in MVVM binding in Scichartsurface? Specifically, I’m looking to create a chart series that can be bound to my ViewModel and support custom styling and data handling.

I have tried following the tutorial found here…

Worked Example – CustomRenderableSeries in MVVM

I was getting a cast error from scicharts. I have attached the picture showing the detailed error.
Concerning the XAML code I have tried both the normal Binding keyword and s:SeriesBinding keyword to the RenderableSeries in the SciChartSurface.

Let me know how to go about this!

i’m using the spline filter with the ToSpline method.
The problem I have with this is that the method returns a different type.
I want to apply the filter to my XyDataSeries<long, double>. However, the returned value is of type XyDataSeries<double, double>.
Is there a way to apply the filter and have a XyDataSeries<long, double>?

I had great success using ObjectModel3D objects in my XAML file. However, I would like to dynamically add and remove objects based on user input. For this reason, I’ve switched to using codebehind.

private void PopulateScene()
          List<Uri> bitmapImages = DataProcessor.bitmapImages();
          Uri textureSource = new Uri(@"C:\Users\Will\Desktop\lemon_yellow__85006.webp");
          var rotation = new Rotation3D()
              Angle = 45,
              Axis = SciChart.Charting3D.Axis.Axis3D.YAxis
          foreach(Uri bitmapImage in bitmapImages)
              ObjectModel3D objectModel = new ObjectModel3D()
                  TextureSource = new TextureSource(textureSource),
                  Source = new ObjectModelSource(new Uri(@"C:\Users\Will\Desktop\EarthTile.obj")),
                  Position = new Vector3(1, 0, 1),
                  CoordinateMode = ObjectCoordinateMode.Relative,
                  Scale = new Vector3(2, 1, 1),
                  Rotation = rotation
              using (sciChart.SuspendUpdates())

I get the correct model with the correct texture. However, setting the position, scale or rotation doesn’t seem to work. All objects are in the same place ((0, 0, 0), no matter the coordinate mode), at the same (1, ,1 ,1) scale, and facing the same direction. How

I also have this function;

private void ClearScene()
using (sciChart.SuspendUpdates())

Even after the object is cleared from SceneObjects, it persists in the chart.

This leads me to my 2 questions;

  1. How do I get the objects I add to the chart to observe the
    transformational parameters I give it? I don’t need to change the
    parameters of objects after they’ve been added to the scene, just
  2. How do I remove objects from a scene?

I have a problem with disappearing points on refresh.
I have a measuring process in progress, so my new data coming continously. When the next data is added to my collection, it refreshes the whole graph (Clear, then re-add every point). Sometimes (sporadically) it happens, that some of my points are invisible, but after something changes (new point is added/zooming in the chart etc…) everything is back to normal again.

I have attached a gif, where I have all my 100 points arrived, but only 29 is visible. I need visible points every time.

(I am using ObservableCollection, when CollectionChanged is triggered, I clear my XyDataSeries and add every element from my collection.)

Could you please give me some hint?

Thank you!

I saw an obj file appear on the chart through SceneObject But I want to use custom polygon as a point marker for my ScatterRenderableSeries. Can you apply obj file to PointMarker3D? Or How do I add 3d polygon to chart via obj file in viewmodel?

I’m creating a custom modifier that is derived from a VerticalSliceModifier. Basically if I press CTRL+Click, a VerticalLineAnnotation is added to the VerticalLines property, and tooltips with Y values are displayed. I’m using a collection of LineRenderableSeriesViewModel as data to chart. It works with one detail: my chart is within a tab, and when the tab changes and then returns, the tooltips disappear.

After further investigation, I noticed that the SeriesData ends up with 0 elements after the tab switch. To fix this, I have overrided the OnPropertyChanged on the class, and if the property that changed is “IWindowService”, I remove all markers if new value is null and add them back when new value is not null.

I don’t know why the “IWindowService” property is changed, or what the implications of that are. So even when the solution works, I don’t understand the internal mechanics of why it does.
I feel like there should be a better way to solve this. Can you help me out, or at least explain the internal workings?

I tried using the OnAttach and OnDetached events, but even when I remove the VerticalLines, somehow they keep appearing on the chart, and are not listed in the new VerticalLines collection.

we are building an application where Charts are created/placed by the user in a form of editor.

We observed that the creation of the first Chart takes between 1 to 3 seconds (depending on the system) but the creation of subsequent Charts takes virtually no time (as it should be).

We assume that the creation of the first Chart involves some kind of time consuming initialization that is later used in the creation of subsequent Charts.

So we have researched if there is a way to do this initialization at the start of our application, so the user is not inconvenienced by a three second waiting time while placing the first Chart.

We discovered the “LoadLibrariesAndLicenseAsync”-function. However, it looks like it has no measurable effect.

Maybe we are using it wrong?

Here is an example code to illustrate the problem in a condensed manner:

Two charts are created and each time the time it takes to create them is measured.

The first creation takes about 1600 milliseconds, the second one only 2.

How can we make both creations only take a few milliseconds?

Thank you.

        // SciChartSurface.SetRuntimeLicenseKey("our key");

         await SciChart.Charting.Visuals.SciChart2DInitializer.LoadLibrariesAndLicenseAsync(
           "our key",
            null); //...does not seem to work

Hi SciChart!

I’m building a real-time data chart, and I wanted to add a SciChartOverview like the “Realtime Ticking Stock Chart” has.
But for some reason, when the user drags the overview to one of the edges, the XVisibleRange stops the updates.

The XAML, the relevant ViewModel, the update method and a short video that demonsrate the problem are attached.

Hi there.

When using PixelPointMarker3D, it seems that it does not work depending on the version of “SciChart.Charting3D.dll”.

Here is my code.

    <s3D:PointLineRenderableSeries3D IsLineStrips="False" StrokeThickness="4">
            <s3D:PixelPointMarker3D SelectedFill="Red"/>
. . .
        <s3D:VertexSelectionModifier3D ExecuteOn="MouseRightButton" />

When i use a dll in the “%AppData%\Local\Programs\SciChart\SciChart SDK\ExampleBin\net6.0-windows\SciChart.Charting3D.dll” path, It works fine as follows.
(Dll Version:

On the other hand, when referring to SciChart3D received through Nuget, it does not work as shown below.
(Nuget Package Version:

It seems that TooltipModifier3D also behaves in the same way.
Is there any solution for the above trouble?

Best Regards.

Hello, I’m using the trial version currently and everything is working great.
I was wondering is there is any way to freeze the chart like I’m looking at pictures while the chart appends new data or save somehow the data points until I will finish my zoom(also if I can move while zooming).
I’m new developer and I have some Idea how to do that but I don’t what will be the right way to do so.

Memory leak in Fifo mode with Visual Xccelerator Engine enabled.

Two screenshots with Visual Xccelerator Engine enabled and disabled.
In a real application, the behavior is repeated. GS.Collect does not solve the problem.

It looks like the problem occurs on the integrated video card. AMD. When switching to a discrete video card. Memory is stable.

Hi I am using UniformXyDataSeries<double> .
And I can’t work with SciChartOverview.
Before that I was working with XyDataSeries<double, double> and everything worked very well.
And now the entire SciChartOverview is simply black.. (still functions as a scrollbar)
And I get this –

SciChartSurface didn’t render, because an exception was thrown:

This is the code:

           x:Name="sciChart0" ... >  <s:SciChartSurface.RenderableSeries >
                        <s:FastLineRenderableSeries x:Name="RenderableSeries0"  DataSeries="{Binding samples[0]._Series, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

                <s:SciChartOverview  x:Name="sciChart0Overview" MouseWheel="sciChart0Overview_MouseWheel" Margin="10,0,10,0"
                                    DataSeries="{Binding ElementName=sciChart0, Path=RenderableSeries[0].DataSeries}"
                                    ParentSurface="{Binding ElementName=sciChart0}" Height="50" VerticalAlignment="Bottom"
                                    SelectedRange="{Binding ElementName=sciChart0, Path=XAxis.VisibleRange, Mode=TwoWay}"
                                     ToolTip="Use the mouse wheel to change the sample shown here."

Again – everything worked fine for me until I changed the data structure…
[samples[0]._Series is type of UniformXyDataSeries<double>()]

I would like to implement a simple FastColumnRenderableSeries with an HorizontalLineAnnotation. But I would like it to be sideways.

Here is my current code:

        g = new FastColumnRenderableSeries();
          colums = new UniformXyDataSeries<double>();>          
          using (m_sciChartSurface.SuspendUpdates())
          g.DataSeries = colums;
          m_xAxis = new NumericAxis();
          m_yAxis = new NumericAxis();
          m_sciChartSurface.XAxis = m_xAxis;
          m_sciChartSurface.YAxis = m_yAxis;
          m_xAxis.Visibility = System.Windows.Visibility.Hidden;
          m_yAxis.AutoRange = AutoRange.Never;
          m_yAxis.VisibleRange = new DoubleRange(-3, 2);
          HorizontalLineAnnotation hla = new HorizontalLineAnnotation();
          hla.Y1 = 1;           
          hla.StrokeThickness = 5;
          hla.Stroke = Brushes.Red;  
              m_xAxis.AxisAlignment = AxisAlignment.Left;
              m_xAxis.FlipCoordinates = true;
              m_yAxis.AxisAlignment = AxisAlignment.Top;
              m_yAxis.FlipCoordinates = true;

However, the HorizontalLineAnnotation behaves strangely.

Anny suggestions?

Thank you.

I’m working with Custom Meshes. I want the user to be able to delete and create an arbitrary number of meshes. It’s fine if there’s a maximum number of meshes that can exist at a time. However, by repeatedly clearing and creating the same mesh, I get this error;

System.InvalidOperationException: ‘The Maximum Mesh ID has been exceeded. Please see

I get the error when I try to add a FreeSurfaceRenderableSeries3D object to the a Scichart3DSurface.RenderableSeries. The link provided by the error got 404’d. I have sixteen SceneObject objects and one TextSceneEntity, borrowed from the example suite. While reproducing the error, I never had more than one mesh. I cleared the RenderableSeries before inserting another mesh.

Is it possible to keep adding meshes as long as I delete them, or does a SciChart3DSurface have a maximum number of meshes that can be added, even with deletion?

I have an analog and scatter chart on separate tabs and when I change for the tab with the scatter chart, after a bit the chart starts to flicker with the data on the chart and the axes values moving quickly up and down and in a few seconds, it’ll become still and won’t move anymore until I change tabs again. It looks like if it would like to scale the Y axis values really quickly, but it’s the same before and after the flickering, which is totally correct, so there is no need to do anything like this. It happens both if I put data to the series dynamically and if there is no data update also. What can cause this behavior?

This is my chart in the XAML:

<s:SciChartSurface x:Name="ScatterChart"
   RenderableSeries="{Binding ScatterRenderSeries}" 
   Margin="10,0" >

        <s:XAxisDragModifier DragMode="Scale"/>
        <s:YAxisDragModifier AxisId="LeftAxis" DragMode="Scale"/>
        <s:YAxisDragModifier AxisId="RightAxis" DragMode="Scale"/>
        <sciChart6Controls:NotifyingMouseWheelZoomModifier IsEnabled="true" ReceiveHandledEvents="True"/>
        <s:MouseWheelZoomModifier IsEnabled="True" ActionType="Zoom" XyDirection="XYDirection"/>

I’ve faced a strange issue, chart display normally in prevew window under anycpu configuration, once changed the configuration to x64, tha chart not display with no error message. I’ve tied on two computers, erase system harddisk, reinstall window, only install vs2019 and scichart wpf7, and the issue is same. Other wpf controls work normally only scichart has this issue. The program is running normally, only in preview has this issue.

And it’s OK in VS 2022, same project open in VS 2022, x64 configuration preview display normally.
Any solution? Thanks.

I am creating a graph for 10 data series using Scichart, with the most optimal legend placement for the graph being “Top” with Horizontal Orientation as shown in the code below. I would like to keep the spacing compact so all the data series can be visible without the need for the scrollbar, however because of the checkboxes for selecting each series being enabled I cannot compress the spaces to make all the data series visible. I did try using a custom legend with the typical binding but to no avail. I have attached an image of the current legend as well.

<s:LegendModifier Name="legendModifier" Margin="1" Width="1" ShowLegend="True" Orientation="Horizontal"
                                  HorizontalAlignment="Left" VerticalAlignment="Top"
                                  LegendPlacement="Top" ScrollViewer.HorizontalScrollBarVisibility="Auto"

Is it possible to format the legend so as to keep all the series names visible while maintaining the checkboxes for displaying or hiding individual data series?

I just want to override the ChartModifier property in the style

I have tree charts one after the other and only the last chart has a legend. It seems I cannot use a style with the same key multiple times.

<Style x:Key="ChartWithMyModifiers" TargetType="{x:Type s:SciChartSurface}">
    <Setter Property="ChartModifier">
                <s:ZoomPanModifier ExecuteOn="MouseRightButton" ClipModeX="None" />
                <s:YAxisDragModifier DragMode="Scale"/>
                <s:XAxisDragModifier DragMode="Scale"/>
                <s:ZoomExtentsModifier ExecuteOn="MouseDoubleClick" />
                <s:LegendModifier ShowLegend="True"/>

The result screen is attached.
Thanks, Gabor

I made a custom modifier and tried to capture a keydown event in Custom Modifiers in abstract “Overriding Key Events” described. The problem is that this event is only fired when SciChartSurface is on focus but for standard modifier like MouseWheelModifier it is working properly. Is there any way to capture the event for whole application?

I am trying to add a BoxAnnotation with MVVM pattern where the X-Axis is a DateTime axis. The annotation can be dragged into the X-direction.
