Thanks for this reference. Would you mind pointing me to the equivalent source file for the primary axis painters? It would help me resolve the other issue I posted: Remove Axis Tick Labels :
I see that the vtkAxis class supports independent booleans LabelsVisible and TicksVisible, although in vtkContext2DScalarBarActor.cxx the two are toggled together. This means that there is not a way to independently toggle the visibility of the tick marks and the numerical labels, which is precisely what I am trying to do in the other issue. I just need to locate the source for the primary axis configuration to implement this change.
Thanks!
