Drawing a graph by script

[Björnke von Gierke]

The easiest way would be to buy malte's new chart engine (available on  
the rev site).

If you're more interested in the learning experience, i suggest  
setting the points of a graphic. if you have an empty line in the  
points of a graphic, the two points above and below it won't be  
connected, so you can even make the grid and the actual graph from the  
same graphic. It's very easy to scale this to several heights: Just  
use a very large rect as orignal, then shrink to your desired size.

On the other hand, if you set the markers, you'll get graph markers  
for free, so to say. But then you can't use the same graphic for  
everything at once.
