[MacRuby-devel] CorePlot success?

[Laurent Sansonetti]

Hi Russ,

After a quick look, I suspect a problem with NSDecimal, as both CPDecimalFromFloat and +plotRangeWithLocation:length: use it.  However I'm unable to reproduce a similar error just playing with NSDecimal directly in MacRuby.

$ ./miniruby -e "framework 'Foundation'; p NSDecimalString(42.decimalValue, nil)"
"42"

The goal of integrating CorePlot is to provide nice graphs of the results (without having to rely on a WebView + javascript graphing libraries).
