[Moose-dev] Dynamic Graphs and RTComposer

Hi all! I want to build a dynamic graph on a composer.. Is that possible? It throws up an error on 'b add:ds', ie. when I want to add the dataset. It throws a 'MessageNotUnderstood' error. Can't I pass the Dynamic Grapher a RTStackedDataSet? Thanks! buildDynamicGraph:anObjectArray onComposer:aComposer | b ds | b := RTDynamicGrapher new. b view: aComposer view. ds := RTStackedDataSet new. ds points: anObjectArray. ds y: #second. ds barShape width: 30. ds histogramWithBarTitle: #first rotation: 0. b add: ds. b axisX noLabel; noTick. b build. ^ b
