How to make the value of color bar show that of defined in table?

Hi Marco,
I use build_lut function to define a colormap bar. How can I make the value beside the color bar show the value defined in lookup table?
Thank you very much!
Here is the definition of lut:

      lut = build_lut([(0,(150,0,0)),
                      (0.35,(255,0,0)),
                      (0.5,(255,150,0)),
                      (0.6,(255,200,0)),
                      (0.75,(255,250,0)),
                      (1,(100,255,0)),
                      (1.5,(0,200,0)),
                      (2,(0,150,0)),
                      (3,(0,200,200)),
                      (4,(0,150,255)),
                      (5,(0,85,255)),
                      (6,(0,0,255)),],
                      vmin=0,vmax=7,below_color=(150,0,0),above_color=(0,0,255),nan_color=(0,0,255),below_alpha=0.68,above_alpha=0.68,nan_alpha=0.18,interpolate=False)

Hi, At the moment this is not possible in the 2D version of the scalarbar,
It should be doable in the 3D version - check this example.

OK. Thanks.
