I am using MS Chart Control 3.5 and four series.  Each series has 500 points and I"m using the DataBindXY method to bind data from array.

If I draw two waveforms in MSChart, the postback controls on the webapplication are fast and response.  If I add a third, it slows down a bit.  If I add a fourth series, the applications response tremenedously drops. 
The chart is inside an updatepanel.  I've narrowed it down to the fact that it is caused by the series and also by points.  I can alleviate the situation when I set a lower axis minimum and maximum to reduce the range of the graph.  This will then plot maybe the first 75 points out of 500.  Then the problem goes away.


anyone know why MSChart severely lags the web application?  I've stepped through the drawchart function and it does not hang there.  I suppose it is caused by an internal object function of the MSChart object.
