Hi,
We regret very much for the delay in responding.
You are getting performance issue because Chart is trying to draw all of your points, much of the work that it does here is not going to show on the graph due to the fact that most points are overlapping.A good solution to this issue is to lower the number of data points that you are adding to the chart.In most cases you will have thousands of data points in a chart that is only few hundred pixels wide, which means that there are multiple points per pixel.
There are few things that you should pay attention to when a high performance chart is required. For example you will notice a great performance gain when:
A line chart type is used instead of spline.
Shadows are disabled, specially soft shadows on column chart type.
Setting the DropSeriesPoints property to true.
Gradient and semitransparent colors are not used.
Please see the sample which reduces the CPU usage and maximizes the Chart speed.

Jaya
