I am plotting 1000 point on a windows using PutPixel (hdc, x, y, color) in a
loop. This method seems to be awfully slow when updating (redrawing).
The same slow speed if I use Lineto (hdc, x,y).
Is there anyithing I could do to make faster plotting?
I am using BCX with project file with smart callback option.
Running on 386-20MHz in standard mode.
