Hi Danila,

Please take a look on this thread – Correlating metadata with datapoints. It shows several possible approaches to add additional information for data points in your series.

Hope it helps!

Hi Uwe,

Thanks for your questions. Concerning the coordinate transformation for CategoryAxis, please take a look at this article from our Knowledgebase. The last section explains the case of CategoryAxis.

As to axis initialization, it is not possible to render a CategoryAxis without having any data on associated with it, since it is index-based. So you should append at least 1 data point, or two if you want a certain VisibleRange as the initial one. There is a special Y value reserved for such cases (also for making gaps), it is double.NaN. Therefor you could append a two data points with double.NaN as Y values and then remove/update them when actual data comes.

Hope this helps!

Published workaround.

We are not sure why the DLL file sharpdx_direct3d11_1_effects_x86.dll is not pickled up by the Visual Studio designer, no matter what we try we cannot get it to work either. So we have this workaround.

Please enable DirectX only when NOT in the designer, like so:

    <s:SciChartSurface >
        <s:SciChartSurface.Style>
            <Style TargetType="{x:Type s:SciChartSurface}">
                <Style.Triggers>
                    <!-- Enable DirectX only when not in designer -->
                    <Trigger Property="componentModel:DesignerProperties.IsInDesignMode" Value="False">
                        <Setter Property="s3D:DirectXHelper.TryApplyDirectXRenderer" Value="True" />
                        <Setter Property="s3D:DirectXHelper.FallbackType" Value="{x:Type s:HighQualityRenderSurface}" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </s:SciChartSurface.Style>
        <s:SciChartSurface.XAxis>
            <s:NumericAxis/>
        </s:SciChartSurface.XAxis>
        <s:SciChartSurface.YAxis>
            <s:NumericAxis/>
        </s:SciChartSurface.YAxis>
    </s:SciChartSurface>

Hi Rashid,

You’re probably using steps which were added for v2.x. Please take a look on updated tutorial for v3, but there will be one minor change because v3 is in beta now and instead of :

// Declaring a new Maven repository
maven { url 'https://www.myget.org/F/abtsoftware/maven' }

there should be maven repository for bleeding edge releases where we published beta:

// Declaring a new Maven repository
maven { url 'https://www.myget.org/F/abtsoftware-bleeding-edge/maven' }

Hope this will help you!

Best regards,
Yura

Hi there,

Two ways you can do this – you can set an explicit Width, or MaxWidth on the Y-Axes, or alternatively you can use the attached property SciChartGroup.VerticalChartGroup which will lock the sizes of Y-Axes to the same width.

Example usage:

<!-- A first vertically aligned chart -->
<s:SciChartSurface x:Name="chart0" s:SciChartGroup.VerticalChartGroup="myGroup">
   <!-- RenderableSeries, DataSet, XAxis omitted for brevity -->
</s:SciChartSurface>

<!-- A second vertically aligned chart -->
<s:SciChartSurface x:Name="chart1" s:SciChartGroup.VerticalChartGroup="myGroup">
   <!-- RenderableSeries, DataSet, XAxis omitted for brevity -->
</s:SciChartSurface>

UPDATE

As it happens we’ve coded in to SciChart v3.1 a property to show tooltips on different actions:

/// 

/// Gets or sets when to show tooltips
/// 
public ShowTooltipOptions ShowTooltipOn
{
    get { return (ShowTooltipOptions)GetValue(ShowTooltipOnProperty); }
    set { SetValue(ShowTooltipOnProperty, value); }
}

Where ShowTooltipOn will be defined as

/// 

/// Specifies actions that cause roolover tooltip to be shown
/// 
public enum ShowTooltipOptions
{
    /// 

    /// Show tooltip when mouse is over point
    /// 
    MouseOver,

    /// 

    /// Show tooltip when mouse hovers over the surface
    /// 
    MouseHover,

    /// 

    /// Show tooltip always
    /// 
    Always,

    /// 

    /// Show tooltip when mouse left button is pressed
    /// 
    MouseLeftButtonDown,

    /// 

    /// Show tooltip when mouse right button is pressed
    /// 
    MouseRightButtonDown,

    /// 

    /// Show tooltip when mouse middle button is pressed
    /// 
    MouseMiddleButtonDown
}

This will be available shortly as part of SciChart v3.1.

Hi Sander,

We’ve investigated the issue and done slight changes in order to allow creating a custom AxisInfo. You should derive your own type from AxisInfo, it will act as a ViewModel. Then override the HitTest method on an axis, create and initialize the instance of that type there and return it.

So if you try out the nightly build tomorrow, the following code should do the trick:

    public class CustomAxis : NumericAxis
{
    public override AxisInfo HitTest(IComparable dataValue)
    {
        var result = new CustomAxisInfo { MyProperty1 = "MyProperty1", MyProperty2 = "MyProperty2" };

        var axisInfo = base.HitTest(dataValue);

        // Copy all the values from axisInfo here

        return result;
    }
}

public class CustomAxisInfo : AxisInfo
{
    public string MyProperty1 { get; set; }

    public string MyProperty2 { get; set; }
}

And here is a label template sample:

            <ControlTemplate x:Key="AxisLabelTemplate" TargetType="s:TemplatableControl">
            <Grid>
                <Rectangle Width="100" Height="50" Fill="Yellow"/>
                <TextBlock Text="{Binding MyProperty1}"/>
            </Grid>
        </ControlTemplate>

Also we will consider if we can provide a bit more convenient way to do this in next versions, for instance via a custom LabelProvider.

Please let us know your thoughts about this solution,

Best regards,
Yuriy

Hi Marcin,

Yes, it’s possible to render chart in memory. We have an example in our demo application which we use internally for testing of chart export. You can use it as reference for implementing chart export in memory for your application:

 public void exportChartInMemory() {
    final SciChartSurface sciChartSurface = new SciChartSurface(getActivity());

    setRenderSurface(sciChartSurface, renderSurface);
    sciChartSurface.setTheme(themeId);

    initSurface(sciChartSurface);

    SciChartSurfaceExportUtil.prepareSurfaceForExport(sciChartSurface, 800, 600);

    imageView.setImageBitmap(sciChartSurface.exportToBitmap());
}

Hope that this will help you!

Best regards,

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?
