Hi Alistair!
Yes, this is something we thought about some times ago.
After updating Roassal, try this:
-=-=-=-=-=-=-=-=-=-=-=-=
v := RTView new.
b := [ :someClasses |
g := RTGrapher new.
g view: v.
ds := RTData new.
ds points: someClasses.
ds y: [ :cls | cls numberOfMethods ].
ds x: [ :cls | cls numberOfLinesOfCode ].
g add: ds.
g addDecorator: (RTRangeSelector new callback: [:es |
| classesToZoomIn |
classesToZoomIn := es collect: #model.
v cleanAll.
b value: classesToZoomIn
]).
g build.
].
b value: RTShape withAllSubclasses.
v
-=-=-=-=-=-=-=-=-=-=-=-=
Let me know how it goes.
Cheers,
Alexandre
