Hi Markus,

We would like to inform you that we have obtained the data points by overriding the LabelsGenerated method to meet your requirements. The code snippet and API link are provided below.

public class CustomTrackball : ChartTrackballBehavior

{

    protected override void LabelsGenerated(List<TrackballPointInfo> pointInfos)

    {

        foreach (TrackballPointInfo point in pointInfos)

        {

           // you can access point info related to each creation of trackball

        }

 

        base.LabelsGenerated(pointInfos);

    }

}

<chart:SfCartesianChart.TrackballBehavior>

                <local:CustomTrackball />

</chart:SfCartesianChart.TrackballBehavior>

If you need any further assistance, feel free to ask.
