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 Colin JN Breame wrote: Your sample seems to work if you set the legend to not-visible. However, the output doesn't look quite right...(take a look at the attachment)I guess this means that zedgraph isn't really mono-compatible (or mono isn't zedgraph ready?)...which is a shame 'cos it looks really good.
