Hi Steve,
Is it possible you are using an older paraview? The python code for
xycharts is relatively new. Instead of CreateRenderView() you should have
CreateXYPlotView(). You shouldn't be calling
DataRepresentation3.add_attribute('XArrayName','arc_length')
but just:
DataRepresentation3.XArrayName = 'arc_length'
With the script you posted, DataRepresentation3 won't have the 'XArrayName'
attribute because you called Show when the active view was a render view,
not an XYPlotView.
