Chart stucks when adding infinite values

[djl]

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:

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 

Now I make sure not to add infinte values, but I think this could be done also in function FitView!

Regards
Dirk

Don't feed any infinite values for the chart. Infinite values go to GPU and it interpolates pixels billions of pixels and it appears as a freeze or as very long delay.
