vtkScalarBarActor using trame's VtkLocalView

I found a workaround. It turns out it doesn’t interpolate the colors added to the transfer function. The workaround is to put more colors manually in the transfer function according to the original interpolation:

    for val in np.linspace(0, 1, 100):
        color = colorTransferFunction.GetColor(val)
        colorTransferFunction.AddRGBPoint(val, *color)
