Creating curve chart showing stock market fluctuations with different colors using chart control

Question

Dear All,

I am working with chart control to show stock market fluctuations using asp:chart control.

I am taking one of the value as median to show fluctuations.

Any value greater than median value has to be shown in green(e.g.) whereas any value lesser than median value has to be shown in red(e.g.).

I succeeded in representing the greater values and lesser values in different colors.

I found an exception that the color doesnt fills properly when the value floats from lesser value to greater value or vice versa. (I cant manipulate my data to add in between points)

Please give me a solution to overcome this problem. I tried to attach the image here, but didnt find the image uploader to upload it from my file system.

Thanks
