Intersection points show over trackball info

[DMM]

Can I get the trackball info to be topmost over the intersection points on the series that are highlighted as I move the trackball?

I am getting the intersection points on top of the trackball info and I do not want that.  I still do want the intersection points to be shown when not over the trackball info tooltip.

Thanks!

Hello David,

Indeed the behavior you are observing is not correct and has been identified as bug by our development team. Before a fix is available you can try adjusting the range of your vertical axis in order for the trackball to be displayed on top of the series. Another approach could be to hide the trackball popup and display the information elsewhere in your app like in this online demo.

Hope this helps!

All the best,
Yavor

Hello Martin,

I encountering this issue. Is there a way to influence the location of the info tooltip? So it will not hide the selected point on the graph?

Hello David,

You can manually set the ZIndex to the TrackBallInfoControl like this:

 private void RadCartesianChart_Loaded(object sender, RoutedEventArgs e)
{
	var chart = (RadCartesianChart)sender;
	var trackBallInfo = chart.FindChildByType<TrackBallInfoControl>();
	Canvas.SetZIndex(trackBallInfo, 10);
}

If you want to offset the TrackBallInfoControl so that the intersection points are visible, you can use negative top margin like this:

<telerik:RadCartesianChart.TrackBallInfoStyle>	
	<Style TargetType="telerik:TrackBallInfoControl">
		<Setter Property="Margin" Value="0 -100 0 0" />	
	</Style>
</telerik:RadCartesianChart.TrackBallInfoStyle>

To avoid the clipping of the element, set the CliptToBounds property of RadCartesianChart to False.

<telerik:RadCartesianChart ClipToBounds="False">
