Adding many series gives slow response time (vs. ActiveX)

I have noticed that adding quite a few series (eg. 80) to Teechart .NET makes functions very slow (eg. zooming, panning). When we use TeeChart for ActiveX the response time seems to be fine, but then we have problems using other functions used in .NET. Just wondering if anyone has any suggestions to get response time faster in .NET TeeChart.
Thanks

Hello,
Improving performance is one of the areas we're working on with TeeChart for .NET. The TeeChart processing routines between the ActiveX and C#.NET are virtually identical, the performance difference comes from within the .NET Framework itself. We are looking at optimisation options.
In the short term some improvements may be gained by using the TChart.AutoRepaint property to restrict repaints of the Chart to moments when it is required (ie. after all function updates have been performed).
