Hi Russ, I suspect this CorePlot framework does not include a BridgeSupport file. This could explain why MacRuby cannot use the CPDecimalFromFloat() C function or the kCPDarkGradientTheme C constant (note that it must be called KCPDarkGradientTheme from MacRuby, as constants must always start with a uppercase letter). You can try to generate a BridgeSupport file using gen_bridge_metadata(1). Check out the end of the man page for examples. The generated file should be installed within the framework.

Hmm ... I think I've got some linking/import issues, although the framework is found.

So good, so far, but...

Can you provide a code snippet (irb) reproducing the exact problem you are experiencing?

Has anyone gotten CorePlot working in a MacRuby app?
http://code.google.com/p/core-plot/
I'm working on re-writing the DatePlot app in MacRuby and have had limited success, but I'm currently stuck with problems surrounding:
CPPlotRange.plotRangeWithLocation
and CPDecimalFromFloat
Cheers, russ
