Is there a 2D plotting (charting) library running under GNUStep?

[Marek Peca]

Hello,

I would like to integrate simple 2D line plots into my application. I did 
it few years ago under Athena, so I managed some basic tasks like axis 
autoscaling etc. However, I have heard a lot about quality plotting 
packages under early NeXTStep, so if there is anything ready to use, I 
would better use the much more advanced code by other people, than to 
write my silly hacks (although at least the bare drawing is easy with 
NSBezierPath, there is lot of work with labels, tics etc.).

I have found some OS X and Cocoa user discussions around this topic, 
including references to nxyplot and XYPlotView, and HippoDraw and SciPlot 
as well.

Are there GNUStep compatible ports of any of these old gems?

It seems that HippoDraw has converted to Qt. I know about Gnuplot, but I 
think, that it is almost impossible to be used as a library. Any other 
working classes?


Thank you for your *pointers,
