I'm building an application for a graduate math class. I need to calculate values at each point on a graph and assign a color to that pixel. My problem is that I can't find a way to control the color of a single pixel. There doesn't seem to be a method of the graphics object I'm using that supports that. I've also tried configuring the methods that are there DrawLine, DrawRectangle, DrawEllipse and adjusting settings for the degenerate case of a point. However, the smallest I can get is a 1 pixel by 2 pixel line segment (2 pixels), if I push it smaller, it doesn't output anything at all (0 pixels). How can I control and paint just 1 pixel for my project?

Bitmap.SetPixel is probably your best bet. For this you will likely need to draw to a bitmap and then copy the bitmap to the final destination.

That's doable, in fact it's probably better practice isn't it? Then I can load the bitmap in the onPaint event.
So I'll be manipulating a bitmap directly instead of manipulating a graphics object (like I do when using DrawLine, etc.)? I'll probably be back with bitmap implementation questions later then.
Thanks!
