Hi! I have worked on a new class RTData, intended to replace RTDataSet and RTStackedDataSet. The discussion with Doru made me realize that having two classes does not make sense at all. You can now do: -=-=-=-=-=-=-=-=-= b := RTGrapher new. ds := RTData new. ds points: #(3 2 5 1 3). b add: ds. b -=-=-=-=-=-=-=-=-= b := RTGrapher new. ds := RTData new. ds points: RTShape withAllSubclasses. ds y: #numberOfMethods. ds x: #numberOfLinesOfCode. b add: ds. b -=-=-=-=-=-=-=-=-= b := RTGrapher new. ds := RTData new. ds points: RTShape withAllSubclasses. ds y: #numberOfMethods. b add: ds. b -=-=-=-=-=-=-=-=-= I have marked RTDataSet and RTStackedDataSet as obsolete.
