Add TrackBall to RadCartesianChart.SeriesProvider

[Steve]

Hi,

I want to show the values and the pen names at the cursor location for all my lines on the RadCartesianChart.

I'm using this xaml to display my data as individual lines & I can hide & add/remove items from the bound data "PlotInfos" and it is reflected on the chart:

<telerik:RadCartesianChart.SeriesProvider>
    <telerik:ChartSeriesProvider Source="{Binding FilteredSeriesInfos}">
        <telerik:ChartSeriesProvider.SeriesDescriptors>
            <telerik:CategoricalSeriesDescriptor ItemsSourcePath="PlotInfos"
                                                 CategoryPath="XCat"
                                                 ValuePath="YVal">
                <telerik:CategoricalSeriesDescriptor.Style>
                    <Style TargetType="telerik:LineSeries">
                        <Setter Property="Stroke" Value="{Binding PenBrush}"/>
                    </Style>
                </telerik:CategoricalSeriesDescriptor.Style>
            </telerik:CategoricalSeriesDescriptor>
        </telerik:ChartSeriesProvider.SeriesDescriptors>
    </telerik:ChartSeriesProvider>
</telerik:RadCartesianChart.SeriesProvider>

The charted data is selectable by the user. I can't find any example of TrackBall info being displayed for SeriesProvider charts using bound data. Does anyone have an example?

Thanks in advance, Steve

Hello Steve,

This post seems to be a duplicate of one of your tickets. I have already answered your questions in the other thread. I am copying the answer also here.

Thank you for the provided code snippet. Looking at the code snippet, a custom style is set to the TrackBallInfoStyle and the Template property is overridden by an empty ControlTemplate. I am assuming that this could be the reason behind why the TrackBall does not appear. I have also double check this in a sample project. I am attaching this project so you can check if I am missing something from your implementation.
