How to draw a lot of data quicly?

Hello,

I am trying to visualize my data by creating a waterfall view of my
FFT's but I am uncertain on what controls to use. My initial tests
with Bitmap or GDI+ are painfully slow, but I do not want to rely on
DirectDraw.

Also, a waterfall-view is a lot of data and for each new line a lot of
data have to be moved or copied. How do I go about to store and
manipulate this efficiently? A cyclic buffer?

Any general tips would be very welcome!

Regards,
Jonas
