Hi Youfei,
Thanks for using Syncfusion software.
We have analyzed this.
This can be overcome by setting the below options in chart
[CS] this.chartControl1.ImprovePerformance = true; this.chartControl1.CalcRegions = false; this.chartControl1.NeedPerformance = true;
series1.EnableStyles = false; |
We have made a sample to illustrate this. Find it from the below location
Windows_forms.zip
In this sample , we have added 1000 series and each series has 100 points. Then the series.clear() method is calculated.
This works fine and takes few seconds to clear.
Please let us know if you have any concern.
Thanks,
Jayavigneshwaran
