[Solved] ChartTrackBallBehavior

[Mag]

Hello
I have a LineSeries and i use the track ball behavior to see the points of my line series.
My questions is : can i change that information?? how do i do that?
i have this code:
            <Chart:RadCartesianChart.Behaviors>
                <Chart:ChartTrackBallBehavior TrackInfoUpdated="ChartTrackBallBehavior_TrackInfoUpdated" 
                                              ShowIntersectionPoints="True" />
            </Chart:RadCartesianChart.Behaviors>

how do i implement a style or something similar to personalize the information

Thank you

Hello Mario,

Thank you for contacting us.

There is a ChartTrackBallBehavior.TrackInfoTemplate property that sets the DataTemplate for the displayed info on a per series basis. It has to be attached to the specific series you wish to customize the behavior for. From the context of the TrackInfoTemplate you can extract the DataPoint and the underlying DataItem. I have attached a sample application that demonstrates how you can do this.

I hope this was useful. Please, do not hesitate to contact us if you have further questions.

Thank you,
It helped a lot, but i have another question, i used that on an windows 8 application and i can see the information with the mouse, but i also have the need to use it on a tablet touch, but in that case i can't see the information.
can you tell me how to do it? 
Sorry for my basic English

Hi Mario,

In touch mode the user have to hold over the chart area until the information appears, and then he can move his finger along the chart to see information about different data points.

I hope this was useful. Please, let us know if you have further questions.
