MSChart

Hello experts,
Presently I am working on VB2008 project. I need to plot collected data on Ms Chart.
Data is huge. Arrays generated from this data are having minimum size of 2999000.
There are such 32 arrays to be plotted on Ms chart.
I could plot these data successfully but the problem is delay. Plotting takes minimum 20-25 seconds every time.
I am using DatabindXY(xarray,Yarrays) method.

Could you please suggest me any other way to plot it faster.

Many thanks.

Regards

Sunita
