Setting default colormap settings for *components* of an array

ParaView Support

I’m curious to know whether it’s possible to set default colormap values for components of an array. For example, given the can.ex2 example file, I’d like to have a linear colormap for Magnitude component of DISPL and diverging colormaps for the X, Y, and Z components of DISPL.

However, when I apply the save button in the Color Map Editor:

It only seems to apply the setting to the top-level DISPL array in my ParaView-UserSettings.json file:

"array_lookup_tables": 
{
    "DISPL" : 
    {
        "PVLookupTable" : 
        {
            "RGBPoints" : 
            [
                2.4611168269148833,
                0.86499999999999999,
                0.86499999999999999,
                0.86499999999999999,
                19.983999167132659,
                0.70588235294099999,
                0.015686274509800001,
                0.149019607843
            ]
        }
    },
}

In our specific application, we have a top-level array for stress and then components such as xx, yy, zz, max_principal, von_mises, triaxiality, invariant_1st, etc. Some of these measures are restricted to the positives and so we’d like to prescribe default colormaps per-component.

Unfortunately, it’s not possible to specify different default color maps for components. In fact, it’s not possible to have different color maps for components at all - the color map is specified for the total array only.

Thanks @cory.quammen, is this something that would be a reasonable feature request?
