need help (2d chart, gdi+)

I have to draw a 2d chart. The problem is that I have 64000 x values!, so
the graph MUST be scrollable (left - right). I don't know how to draw that
(and on wich control - label? panel?), does anybody know how to do that, or
is there any free conroll that draws a chart like that?
thanks!!!

Draw it on a panel, which is made scrollable (by putting it inside another
small panel, which has AutoScroll true). Be sure to draw only values visible
on the screen, otherwise you'll get poor performance.

No good, if the panel is for example 100x100 all outside that panel coul'd
not be seen, and when I scroll left and right (I can scroll only if I put
another (invisable) conrol on that panel - on it's right end) everything
that is drawn erases...
