After moving from version: 1.4.1575 to version: 1.4.1611 we are seeing the the Cursor modifier replicating across all the charts in our dashboard. Obviously this is not desirable. I’ve attached screenshots to show this.

Please could you advise?

I am having an issue with the SciChart graphs. I have attached an image – SciChartIssue.png, here which shows the issue. Our SciChart graph contains 8 channels of dataseries for EEG / EMG signals. By default the first channel is selected. When we select/deselect additional channels, they start showing up on the graph accordingly. The issue happens when a channel is de-selected. i.e. when any channel is de-selected, we are clearing that particular channel dataseries, while the other series is being appended and rendered using SuspendUpdates(). But on the graph, the waveform tends to move towards the extreme end of the chart (as seen from the image attached). we were initially using version 5.4 of Scichart. but i later updated it to v6.3, but still have the same issue.
If you are aware or have come across such an issue, then I would appreciate any help or advice from you. Since this is a vast and secure project, I am not able to share the entire code with you at this moment. However, I have attached a xaml & .cs file used to render the graph, If it helps.

Hi sir,

We would like to build a real time updated stackedcolumn chart in mvvm mode.
Is that possible? (x-axis on the left side)(y-axis on the bottom side which can keep update with only 10mins range)

I wonder can I use the StackedColumnRenderableSeriesForMvvm?
I found out this control but have no idea how to use it…

Scenario: user selects an area of a heatmap chart using a box annotation via a mouse drag.

I have created a custom modifier to draw the box annotation. I’ve used this as the basis: SimpleDataPointSelectionModifier.ts

My question is: how to I get the X axis start + end values and the Y axis start + end values based on the area of the annotation/mouse coordinates.

Boxplot widths are not the same as the image below.
Please let me know can we change the size of the box plot chart.

IEnumerable<BoxPoint> boxData = GetBoxPlotData().ToArray();

RenderableSeriesViewModels = new ObservableCollection<IRenderableSeriesViewModel>();
foreach (var data in boxData)
    var boxDataSeries = new BoxPlotDataSeries<double, double>();
    boxDataSeries.Append(data.XValue, data.Median, data.Minimum, data.LowerQuartile, data.UpperQuartile, data.Maximum);

Hello there. At the beginning of the program, I define the workspace as w=10 and h=10 units. I set the new workspace to 5×5 in a button event. The new workspace is created but the old 10×10 volume remains on the screen. When I create the new workspace I want the old one to disappear. Thank you in advance for your help. Good work.

My button event.

btnSetNewWH.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
w = 5;
h = 5;
ds3d = new UniformGridDataSeries3D<>(Double.class, Double.class, Double.class, w, h);      

rs1 = sciChart3DBuilder.newSurfaceMeshSeries3D()
        .withMeshColorPalette(new GradientColorPalette(colors, stops))

Good afternoon,

I wanted to synchronize the mouse events between graphs, but based on the value of the X axis, not on the position within the graph. In the photo attached below, it is seen that the mouse events are synchronized, and the rollover appears in both graphs. However, what I want is that if, for example, in the graph on the left, the mouse is at time 00: 15: 00.000, in the graph on the right, the rollover also appears at position X 00: 15: 00.000, regardless the width of each graph. Until now I have not been able to get it, as seen when on the left it is at the time 00: 22: 37.00 on the right it appears at the point 00: 10: 23.750.

I would need a way to achieve this with code behind, since I create the graphics programmatically and without MVVM.

As extra information, all charts have the same range of X axis values (they all go from the same start time to the same end time)

Thanks a lot!

I’m trying to use AvaloniaUI with .NET Core 3.1 to create an application using SciChart, but I get XAMLIL error when trying to add a SciChartSurface following the code from the tutorial. I used a standard Avalonia MVVM Application template when creating the project.

This is the code:

<UserControl xmlns=""
             mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"

        <!-- Bind to ChartViewModel.ChartTitle etc -->
        <s:SciChartSurface ChartTitle="{Binding ChartTitle}">
                <s:NumericAxis AxisTitle="{Binding XAxisTitle}"/>
                <s:NumericAxis AxisTitle="{Binding YAxisTitle}"/>

And the error I get is:
“XAMLIL: Unable to resolve type SciChartSurface from namespace Line 27, position 4″
which is the first s:SciChartSurface entry.

Any ideas what might be wrong? Does SciChart not work with any framework regardless of using .NET Core 3.0?
I have tried changing between Core 3.0 and 3.1, which does nothing.

I’m using a candlestick series in a slightly unconventional use case, essentially to show a range at a given data point, screenshot below.
enter image description here

This works fine if the number of the data points and window size stays the same, but if I resize the window, the bars shrink accordingly, which I want to avoid.
enter image description here

So basically what I need is some kind of rendering mode that takes in a pixel width for the bars.
I’ve attempted to update the DataPointWidth on the series using a combination of the screen width and the number of points, but it’s extremely messy since the change needed isn’t linear.

I have several vertical line annotations placed on my chart.

(1.) id=9136 at location 1229.8065
(2.) id=8572 at location 1230.0483
(3.) id=8570 at location 1230.1089

At a certain level, the annotations are at the good locations. Before 1230 for (1.) and after, for both next (see image GoodLocation.png).
If I zoom out, (1.)(2.)(3.) labels are shifted to the right (see WrongLocation.png) and the tooltip on (1.) correspond at tooltip (2.)

Can you help me?
In advance thank you for your support

Is it possible to display distinct labels for Y, and Y1 on BandRenderableSeriesViewModel using RollerOverModifier?

I have tried using following code snippet for RolloverModifier.TooltipTemplate, additionally tried using TooltipContainerStyle with a custom template. With these, same tooltip appears on both the lines. Is it possible to
1- Either display tooltip on only one line (e.g. on the red line), and point markers on both lines.
2- Or display a single label with current point markers’s value on each line i.e. Y on Red, and Y1 on green?
3- Set point marker colors to same as line’s as circled on the screenshot?

<DataTemplate x:Key="BandTooltipTemplate" DataType="s:XyySeriesInfo">
    <StackPanel Orientation="Vertical">
        <TextBlock Foreground="White">
            <Run Text="Series: "/>
            <Run Text="{Binding SeriesName, StringFormat='{}{0}:', Mode=OneWay}"/>
        <TextBlock Foreground="White">
            <Run Text="Top: "/>
            <Run Text="{Binding FormattedYValue, Mode=OneWay}"/>
        <TextBlock Foreground="White">
            <Run Text="Bottom: "/>
            <Run Text="{Binding FormattedY1Value, Mode=OneWay}"/>

Existing result screenshot attached.

Hi Scichart Team,
RenderableSeries Hit-Test still having some issues. I saw that the bug on your board is already closed state and my last comments are missed on the bug. So i am adding the same here.

Can you please check the video and the code. Only change i have done on the Example is the data values are updated. On the video you can saw the clicking outside for some area Hit is showing, some area miss is showing, and clicking on the lines or point also showing the same. Let me know you need any more inputs from my side.

Hi there,

I need to display a horizontal column chart so I followed the example for rotating charts:

<s:NumericAxis BorderBrush="Black" BorderThickness="1,0,0,0" x:Name="xAxis" AxisAlignment="Left" Margin="0,20"/>
<s:NumericAxis BorderBrush="Black" BorderThickness="0,0,0,1" AxisAlignment="Top"  FlipCoordinates="True" x:Name="yAxis"  />

And it works as expected.
Now the Problem: I want to be able to move my x-Axis to any given value. For “normal”(y-axis vertical and x-axis horizontal) I use the shifted axis example, but for that to work the axis need to be center axis (or am I missing something?) and with center axis set to true the entire thing looks like in the picture I attached.

Any help would be appreciated.
Thanks in advance.

Would there be a straight-forward way to put the SciChart Legend from a LegendModifier inside a WPF Expander control, to show or hide the legend?

Would ScichartSurface need to be subclassed in order to accomplish this visual?

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.

<s:TradingAnnotationCreationModifierMvvm AnnotationViewModelType="{Binding DataContext.AnnotationCreationVM.AnnotationType, Source={StaticResource ROOT_OHLC_CHART_SPY}}"

                                <ext:EventToCommandBehavior Command="{Binding DataContext.AnnotationCreationVM.AnnotationCreatedCommand, Source={StaticResource ROOT_OHLC_CHART_SPY}}"

Hi there,

I would like to use a column chart with labels. Our client tends to use really long names for these labels, so I was wondering if it is possible that these labels wrap. I could find no property in the docs or source that achieves this. The attached screenshot shows the current (and undesired) rendering.

The current behavior seems to be that labels in between are hidden when longer labels overlap them. Is this a configurable property? In our case, the labels may never be hidden.

Kind regards,

Hi all,

I am trying to create a vertex selection modifier for a 3D chart that would allow me to select everything within two points on an axis. I have inherited from ChartModifierBase and created overrides for the OnModifierMouse events but I need a way to calculate the world or data coordinate of my axis. I know that CameraController has a ScreenToWorldSpace method but this is not exposed on the Camera3D class. Currently I have resorted to calling the TSRCamera’s TransformIntoWorldCoordinates method but would prefer a less roundabout solution. Is there an easier way to calculate screen to world/data coordinates or a way to get the position on my axis from screen coordniates?

        Annotations="{s:AnnotationsBinding Annotations}">

All the examples I’ve seen use the RolloverMarkerTemplate and define it under as a child node under BaseRenderableSeries or FastLineRenderableSeries, but I cannot find how to assign this to a series when it is defined in a ViewModel and assigned as above.

I’m new to SciChart and any help on this would be great.

Currently when we scroll the mouse pointer the zoom level is increasing/decreasing and when we click and drag the pan the chart. I want is when we scroll the chart should change the visible range (Pan chart), and clicking and selecting the area need to zoom like RubberBandXyZoomModifier. But I need to zoom only the X axis. Y axis should be the same as before zoom. Is this possible with SCI chart??

Good evening!
I wrote a test program with your library, the following situation arose:
On Windows 10 everything works fine, and on Windows 7 the following error (for 3D Charts)

XamlParseException: The invocation of the constructor on type 'SciChart.Charting3D.SciChart3DSurface' that matches the specified binding constraints threw an exception.

I ran the SciChart WPF Examples Suite program and saw the same message.

Please tell me what to do (preferably without a new version, I read that only SciCharts 5 work stably for Windows 8 and below)

System Information:
Windows 7 64-bit, 8GB RAM, 1TB SSD, .NET Framework 4.5.2
SciCharts: Version

in version the situation is similar

Hi everyone!

I have a candlestick chart that uses SCIZoomPanModifier() so i can zoom and pan in the chart. I added a SCITooltipModifier() so i can inspect the individual data points. I noticed that by adding the toolTipModifier, that my pan and zoom stops working. I can’t figure out why. Would really appreciate if someone could tell me why or if i am missing some variable i need to set

I’m looking for some direction on how to implement a modifier that reacts to interaction (mouse up/down etc) with a charts axis

  • User clicks on axis
  • Provide callback for side effect when clicked

Hi, I’m looking for some pointers on how to implement the following:

  • User draws a selection on the chart (similar to rubber band modifier)
  • Annotation is drawn on the chart conforming to the users selection
  • Annotation is fixed relative to the data point (e.g. will scroll is the chart is panned etc)

Many thanks

We are using NumericAxis for the y-axis and x-axis of a bar chart. The x-axis uses a LabelProvider (to convert integers to strings) and a TickLabelStyle (to rotate the label by 270 degrees so it is vertical going from the bottom to the top). We find that sometimes the y-axis is not drawn (however, it will be drawn if the chart is resized or re-painted).

The work-around to the problem is adding spaces to the front of the shorter labels so all of the labels are all the same length. However, this work-around does not work for every case.

Have you seen this issue before and is there a better solution? Thanks!

I want to draw a spectrogram in WPF application and after searching I found your control. I downloaded your demo (trial version) and I would want to check if it completely meets my requirements. As starting I try to make zoom-in in your demo and I didn’t succeed.
Maybe you can tell me if it’s supported?
Thank you very much!

I have custom annotations built on the BoxAnnotation base class. The annotations have a rotation feature so that their content can be rotated.
RenderTransform is applied down to BoxAnnotation itself, so that it’s contents are rotated all along with the handlers. But resize grips are staying the same. Is it possible to pass the existing transform (the one applied to the content) also to the grips?
