Chart stucks when adding infinite values
Posted: Wed Oct 09, 2013 7:42 am
Hi,
I was wondering why my application with lighning chart gets stuck sometimes when adding new values to a series.
Then I found out that Apllication freezes in function LightningChartUltimate.EndUpdate without any exception.
Reason is that I added some infinite double values (e.g. double.PositiveInfinity) calculated by function Math.log10.
Freeze only occurs when calling function LightningChartUltimate.ViewXY.FitView() before!
This is a sample code that crashes:
Now I make sure not to add infinte values, but I think this could be done also in function FitView! 
Regards
Dirk

Code: Select all
SeriesPoint[] sp = new SeriesPoint[2];
//Point 1
sp[0].X = 0;
sp[0].Y = 1;
//Point 2
sp[1].X = 2;
sp[1].Y = double.PositiveInfinity; //This values crashes FITView
lightningChartUltimate1.BeginUpdate();
lightningChartUltimate1.ViewXY.PointLineSeries[0].Clear();
lightningChartUltimate1.ViewXY.PointLineSeries[0].Points = sp;
lightningChartUltimate1.ViewXY.FitView(); // No problem if I uncomment this line
lightningChartUltimate1.EndUpdate(); // <--- Application gets stuck here
