I met a technical problem: when the filling of the TeeChart control to the data point to 100000 when the control response speed will be very slow, if continue to increase in number there will be operating lag phenomenon. Encounter this kind of situation how to deal with, TeeChart has optimized data processing? My version of TeeChart is TeeChartNET3VSNET2005

Hi Carl,
I recommend you to do as explained in the
Real-time Charting and
Boosting graphics-rendering performance in Windows Forms articles
here. First one is based on TeeChart VCL but almost the same applies to TeeChart .NET. Second one uses
TeeChart.Direct2D.dll.
I also recommend you to look a the following examples in the features demo:
- All Features\Welcome !\Functions\Extended\Reducing number of points
- All Features\Welcome !\Functions\Extended\Reducing number of points\DownSampling Additions
- All Features\Welcome !\Speed\Realtime charting
- All Features\Welcome !\Speed\Fast Line Speed DrawAll
