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](https://discourse.paraview.org/t/remove-axis-tick-labels/17355) :

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!
