Hi All,

I am facing severe performance problem while refreshing the chart with more then 100 plus points, it says CPU usage is 100% and also control is not responding at all,

Below is my code for refreshing the chart while the scroll bar move then the cursor will be drawn on the particular location.
this.TrendControl.Cursor.Enabled = true;
this.TrendControl.Cursor.Start = this.TrendControl.FromDate.AddSeconds(e.NewValue).ToOADate();
this.TrendControl.Cursor.End = this.TrendControl.FromDate.AddSeconds(e.NewValue).ToOADate() + this.TrendControl.Cursor.Width;


Please tell me is there any other do the same without refreshing the chart? I want to avoid performance problem in my control.

Please any one help as soon as possible.

Thanks and Regards
