[Mono-list] mono charting

Hi colin, hi all,

You're right, the output looks ugly :-)
As an additionl information to anybody willing to debug/better 
System.Drawing and libgdiplus, the expected result is:
http://zedgraph.org/wiki/index.php?title=Image:Piedemo.png

I think zedGraph doesn't have to mono-compatible, it is pure managed 
.Net, so mono should be able to run it 100%.
Could this library be a good basis to debug and make drawing parts of 
mono better? I don't know anything about regression tests, unit tests, 
but could we use the samples from zedgraph.org, compare them regularly 
with what zedgraph outputs under mono, in order to test compatibility 
between MS and Mono frameworks?

I'm going to investigate more, maybe will I be able to find more 
precisely what drawing functions don't work as expected in mono.

Regards,

Matth
