ChartView Trackball

[Obalesu]

Hi Support Team,

I am showing two series data in chartview.I want to show trackball to only one series.
How can i hide the trackball to other(second) series.

Please find attached screenshot for your reference.



Thanks&Regards

Hi Obalesu,

All you need to do is populate the TrackBallInfoTemplate property of the second series with an empty instance of DataTemplate. This way the chart will not show any information about that series in the trackball info.


Kind regards,

This is not working for Windows Phone :-( the trackballinfo always comes up on longpress!!

... 
<telerikChart:AreaSeries
    StrokeMode="Points"

    StrokeThickness="2"

    ValueBinding="<some name>"

    CategoryBinding="<some name>"

    ItemsSource="{Binding <some source>}"

    ToolTipService.Placement="Top">

    <telerikChart:AreaSeries.TrackBallInfoTemplate>

       <DataTemplate />

    </telerikChart:AreaSeries.TrackBallInfoTemplate>
...

Hello Frederik,

The TrackBallInfo comes up when you perform a hold gesture on the chart, but it doesn't contain information about the series, which have an empty DataTemplate set as TrackBallInfoTemplate. You can read more about this feature in RadChart for Windows Phone here.

If you need additional assistance, don't hesitate to get back to us with your question.
