Hi Syncfusion,
I am getting the exception I added the image of the exception.
what I did is add SFRangeAreaSeries in the rangeArea don't have null point but I added more series with null points.
what happened is that I see the chart with the series
and if I don't add the trackball everything works fine,
but I add the trackball behavior without doing anything space I get this exception
Thanks, Roi
