In reply to: Request for Assistance: Displaying 2D Byte Array on SciChart 3D Chart

Hello Mr. Nha,

Thanks for your inquiry.
We can recommend you using our Uniform Surface Mesh chart type. Please find the corresponding documentation article below:
https://www.scichart.com/documentation/win/current/webframe.html#The%20SurfaceMesh%203D%20Chart%20Type.html

Please note: to see the C# code sample you can switch to it on the “XAML / CS” tab control.

Additionally, to use SciChart WPF inside your WinForms application you can use a WinForms ElementHost control. Here you can find one of the examples:
https://www.wpf-controls.com/hosting-a-wpf-control-in-winforms/

Hope this helps.

In reply to: Edit MouseWheelZoomModifier Behavior

Hi Ben,

We discussed your inquiry.
To change the zooming direction you can override the OverrideKeyboardAction() method and change ActionTypeProperty and XyDirectionProperty values.
Please find the default OverrideKeyboardAction() method implementation below:

        protected virtual void OverrideKeyboardAction(MouseModifier modifier)
    {
        if (ExecuteWhen == MouseModifier.None)
        {
            if (modifier == MouseModifier.Ctrl)
            {
                this.SetCurrentValue(ActionTypeProperty, ActionType.Pan);
                this.SetCurrentValue(XyDirectionProperty, XyDirection.YDirection);
            }
            else if (modifier == MouseModifier.Shift)
            {
                this.SetCurrentValue(ActionTypeProperty, ActionType.Pan);
                this.SetCurrentValue(XyDirectionProperty, XyDirection.XDirection);
            }
        }
    }

In reply to: AutoRange.Once does not work for the default range

This is a known issue due to the way we detect if the axis is in its default state. We are taking a look to see if there is a simple and safe way we can sort out.

In reply to: Chart blank out and unable to display from the error related to TextLabelProvider.getLabelTexture.

Hi Suzanne,

Firstly, we recommend providing code to reproduce this error. You can share this with us in a codepen, or a codesandbox. Instructions on how to do this can be found here: https://www.scichart.com/blog/codepen-codesandbox-and-jsfiddle-support-in-scichart-js

Next, we also recommend trying that same code to reproduce against the latest version of SciChart: v3.3. The version you are using (v3.0) is not the latest and could have bugs or issues in it.

We will await your update with code to reproduce before providing further assistance.

Best regards,
Andrew

In reply to: Why does the Text property for a TextAnnotation not reflect the current text until the focus is moved?

Hi Jamie,

Thanks for your inquiry.
This is the default behavior of WPF TextBox, which is used under the hood of our TextAnnotation.

We would suggest you try forcing Focus to any other control before saving the data. This can be done using WPF capabilities, for instance, FocusManager:
https://learn.microsoft.com/en-us/dotnet/api/system.windows.input.focusmanager.setfocusedelement?view=windowsdesktop-8.0

Alternatively, you can override the TextAnnotation Template to update it on a keypress:
https://learn.microsoft.com/en-us/dotnet/desktop/wpf/data/how-to-control-when-the-textbox-text-updates-the-source?view=netframeworkdesktop-4.8

Please let us know if you are interested in this option. We can share the default Template.

Kind regards,

In reply to: How to bind to RenderableSeries

The background pattern in the Overview can be removed by how?

In reply to: How to bind to RenderableSeries

Hi Jeong,

This can’t really be done like this. RenderableSeries are FrameworkElements and shouldn’t be declared in a ViewModel.

There are two ways to bind to RenderableSeries in SciChart WPF:

Method 1: declare RenderableSeries in XAML and bind to DataSeries in ViewModel

e.g.

<!-- where xmlns:s="http://schemas.abtsoftware.co.uk/scichart" -->
<s:SciChartSurface>

    <s:SciChartSurface.RenderableSeries>
        <s:FastLineRenderableSeries DataSeries="{Binding DataSeries}"
                                    StrokeThickness="1" StrokeDashArray="2 2"
                                    Stroke="OrangeRed"/>
    </s:SciChartSurface.RenderableSeries>

    <!--  XAxis, YAxis omitted for brevity  -->

</s:SciChartSurface>

// Viewmodel
class ViewModel 
{
    public XyDataSeries DataSeries { get; set; }
}

With this method your number of RenderableSeries are fixed but you can modify the data from a view model.

Method 2: Declare RenderableSeriesViewModels in XAML and bind to SciChartSurface.RenderableSeries with the SeriesBinding Markup extension

e.g.

<!-- Declare a SciChartSurface with SeriesBinding -->
<!-- Where xmlns:s="http://schemas.abtsoftware.co.uk/scichart -->
<s:SciChartSurface RenderableSeries="{s:SeriesBinding RenderableSeriesViewModels}">

   <!-- XAxis, YAxis omitted for brevity -->

</s:SciChartSurface>

private ObservableCollection<IRenderableSeriesViewModel> _renderSeriesViewModels;
public ObservableCollection<IRenderableSeriesViewModel> RenderableSeriesViewModels
{
   get { return _renderSeriesViewModels; }
   set
   {
      _renderSeriesViewModels = value;
         OnPropertyChanged("RenderableSeriesViewModels");
   }
}

With this method you have full control over adding, removing renderable series as well as modifying the data from the view model.

In reply to: Why in MountainRenderable I set XRange(0, 9), but chart always show gap?

Hi Lex,
I follow the suggestion, set GrowBy to “0.0, 0.0”, and update my xaml code

<s:SciStockChart.XAxisStyle>
    <Style TargetType="s:CategoryDateTimeAxis">
        <Setter Property="FontSize" Value="{DynamicResource GlobalFontSize10}"/>
        <Setter Property="DrawLabels" Value="True" />
        <Setter Property="DrawMinorTicks" Value="False" />
        <Setter Property="DrawMajorTicks" Value="False" />
        <Setter Property="DrawMajorBands" Value="False" />
        <Setter Property="DrawMajorGridLines" Value="False" />
        <Setter Property="DrawMinorGridLines" Value="False" />
        <Setter Property="TextFormatting" Value="{Binding XAxisTextFormatting}" />
        <Setter Property="VisibleRange" Value="{Binding ParentViewModel.XRange, Mode=TwoWay}" />
        <Setter Property="VisibleRangeLimit" Value="{Binding ParentViewModel.XRangeLimit}"/>
        <Setter Property="AutoRange" Value="{Binding ParentViewModel.AutoRangeX}"/>
        <Setter Property="GrowBy" Value="0.0, 0.0"/>
    </Style>
</s:SciStockChart.XAxisStyle>

But the result is same, do I missing something?

In reply to: Why in MountainRenderable I set XRange(0, 9), but chart always show gap?

Hi Chia Chun Tang,

Thanks for your question.
SciStockChart is a preconfigured SciChartSurface version having some properties on its elements set to default values. Please take a look at the corresponding article for more info:
https://www.scichart.com/documentation/win/current/webframe.html#SciStockChart%20-%20Simplified%20Financial%20Charts.html

The spaces you see on the sides are controlled by the Axis.GrowBy property:
https://www.scichart.com/documentation/win/current/webframe.html#SciChart.Charting~SciChart.Charting.Visuals.Axes.AxisCore~GrowBy.html

To get rid of these spaces you can override the default value by setting the GrowBy property for the XAxis to “0.0, 0.0”.

In reply to: SciChartVerticalGroup resets axes layout strategies

This task is now done and released as of version 3.2.575. SciChartVerticalGroup will now copy LayoutStrategies from the existing LayoutManager onto it’s SynchronisedLayoutManager so custom synchronised layouts will just work.

In reply to: The selected event for the LegendModifier checkbox

Is your question related to WPF (Windows charts) or JS (JavaScript charts)?

In SciChart.js there is a mechanism to get a callback on legend checkbox changed. See the LegendModifier documentation.

Subscribing to Checkbox Checked Changed

As well as subscribing to BaseRenderableSeries.isVisibleChanged, you
can now subscribe to LegendModifier.isCheckedChanged event. This can
be done either in the constructor options to LegendModifier or after
creation.

const legend = new LegendModifier({
      showCheckboxes: true,
      showSeriesMarkers: true,
      showLegend: true,
      // Subscribe to checked changed here
      isCheckedChangedCallback: (series, isChecked) => {
          console.log(`Option 1: Legend item ${series.type} isChecked=${isChecked}`);   
      }
  });
  // Or here after instantiation
  legend.isCheckedChanged.subscribe((args) => {
      console.log(`Option 2: Legend item ${args.series.type} isChecked=${args.isChecked}`);
  });
  // Add the legend to the chart
  sciChartSurface.chartModifiers.add(legend);

In reply to: Bar chart selection/hover mouse interaction

Hi there,

Please find attached an example that demonstrates how to use SciChart API to achieve the desired behavior.

The example utilizes PointMetadata API to add Selectable and Hoverable state to data points and Palette Provider API to change Fill color of individual columns depending of the state of the underlying data point. Also, a simple custom Chart Modifier is used to implement state changing behavior on Mouse events and trigger a chart redraw when such change occurs.

Please let me know if you have any questions regarding the example or any SciChart APIs that are used.
