Chart Trackball exception

[Tomasz Wisniewski]

When I enable trackball in chart control and collection of points in chart is empty a get an exception:

Specified argument was out of the range of valid values.

System.ArgumentOutOfRangeException
   at System.ThrowHelper.ThrowArgumentOutOfRangeException()
   at System.Collections.Generic.List`1.get_Item(Int32 index)
   at Syncfusion.UI.Xaml.Charts.ChartSeries.FindNearestChartPoint(Point point, Double& x, Double& y, Double& stackedYValue)
   at Syncfusion.UI.Xaml.Charts.ChartTrackBallBehavior.OnPointerPositionChanged(Point point)
   at Syncfusion.UI.Xaml.Charts.ChartTrackBallBehavior.OnPointerMoved(PointerRoutedEventArgs e)
   at Syncfusion.UI.Xaml.Charts.Chart.OnPointerMoved(PointerRoutedEventArgs e)

 

When I enter the page with chart control chart is still empty, because I have to read values from files and it takes a second. I guess you could add  condition to check this situation.

One more thing: it seems that even one point in chart is too less. We have to have at least 2 points in chart to get rid of exception.
