I have configured the ChartTrackballController and added it to the ChartView. The event does fire, but there are times when it does not. I can move the mouse pointer left and right over the chart and most of the time the text is updated and displayed. However, there are times when the mouse is moved the data point is moved but the trackball information is not moved or updated. The event never fires.
Is this a known issue?
// Configure the trackball.
var trackball = new ChartTrackballController();
pingChart.Controllers.Add(trackball);
pingChart.ShowTrackBall = true;
trackball.TextNeeded += TrackballTextNeeded;
private void TrackballTextNeeded(object sender, TextNeededEventArgs e)
{
Debug.WriteLine("{0} - trackball calculation.", DateTime.Now);
e.Text = "Test...";
}
