How can i draw a diagram like the one in Excel with (X,Y) values ??

[Beginner]

If im to draw something like that ? What approach would i use ?

Ofcourse the 4 columns are hidden and done by internall calculation. I want to select their values and draw them. How may i do that ?

You could either use the Graphics class, or a third party component. If you really want it Excel-style, I'd recommend ComponentOne's C1Chart.
