How do I build a simple line graph/chart

I have built a very VERY simple agent-based market simulation, as a test, very loosely based on this article (if any one is interested) : http://www.gamasutra.com/blogs/LarsDouc ... Engine.php

How do I build a simple line graph/chart so that I can have a visual representation of the evolution of prices over time?

Use a 1 pixel width line stretched from each data point to the next. Set length and angle with a little math.

Or use the Canvas third party plugin to draw lines.

I'm interested to have a look at your simulation
