Summary0008543: Color bar from python
DescriptionMake is easy to create/access scalar bar/color bar from python.
Steps To Reproduce
Additional InformationConvesation:
Ken: How do you turn on the color bar from Python?

Berk: Not easy to do....

Ken: Can we move the responsibility of scalar bar management to the representation object? That way, either the GUI or a python script need only turn on a flag in the representation and the lookup table and range will be set up for you. It could also satisfy a request from the mailing list to keep the scalar bar up (or down) when changing variables to color by.

This is easy nowadays:

# create a new 'Sphere'
sphere1 = Sphere()

# get active view
renderView1 = GetActiveViewOrCreate('RenderView')

# show data in view
sphere1Display = Show(sphere1, renderView1)

# set scalar coloring
ColorBy(sphere1Display, ('POINTS', 'Normals'))

# show color bar/color legend
sphere1Display.SetScalarBarVisibility(renderView1, True)

# get color transfer function/color map for 'Normals'
normalsLUT = GetColorTransferFunction('Normals')

# get opacity transfer function/opacity map for 'Normals'
normalsPWF = GetOpacityTransferFunction('Normals')

Testing directions below miss a Render(). After using a Render, this worked correctly.

Tested local server, Linux, master.
