In the example program, below, the sphere appears with the expected colormap but the colormap legend does not. Am I creating the legend B the right way? How should I connect B to V?

Can anyone suggest how to do this?

TIA!

from paraview import servermanager
servermanager.Connect()
V = servermanager.CreateRenderView()

C = servermanager.rendering.PVLookupTable()
C.ColorSpace = 1
C.RGBPoints = ( 0,1,0,0, 1,1,1,0 )

S = servermanager.sources.SphereSource()

SR = servermanager.CreateRepresentation( S, V )
SR.LookupTable = C
SR.ColorAttributeType = 0
SR.ColorArrayName = "Normals"

B = servermanager.vtkSMScalarBarActorProxy()
B.LookupTable = C
B.Position = [0.5, 0.2]

V.StillRender()
V.ResetCamera()
V.StillRender()
