[MacRuby-devel] CorePlot success?

[Russ McBride]

Thanks for the suggestions, Laurent.  

I re-generated the BridgeSupport version with a 64-bit-specific version, then ran a diff on the old version and new version and the content appears the same.  The file is in /Library/Frameworks/CorePlot.framework/Resources/BridgeSupport/CorePlot.bridgesupport

And I replaced my MacRuby install with the latest nightly.

Now I get this:

>> framework 'cocoa'
=> true
>> framework 'coreplot'
=> true
>> a = 4.2
=> 4.2
>> z = CPDecimalFromFloat(a)
TypeError: invalid bitfield type: b

>> z = CPDecimalFromFloat(a)
Segmentation fault

...


>> xLow = 0.0
=> 0.0
>> xLow = NSNumber.numberWithFloat(xLow.to_f).decimalValue
=> #<NSDecimal:0x2005bfae0>
>> fDays = 398.0
=> 398.0
>> fDays = NSNumber.numberWithFloat(fDays.to_f).decimalValue
=> #<NSDecimal:0x2005fbf00>
>> xrange = CPPlotRange.plotRangeWithLocation(xLow, length:fDays)
TypeError: invalid bitfield type: b
	
>> xrange = CPPlotRange.plotRangeWithLocation(xLow, length:fDays)
Segmentation fault



This still works, though:

>> theme = CPTheme.themeNamed(KCPDarkGradientTheme)
=> #<CPDarkGradientTheme:0x2005c4560>


On a different topic, I've had great fun writing tools with MacRuby + Selenium to probe some of our web apps here at UC Berkeley for performance numbers.  The goal of integrating CorePlot is to provide nice graphs of the results (without having to rely on a WebView + javascript graphing libraries).

Cheers,
Russ
