When we get matplotlib graphics, can we have full colour (RGB) plots taking red, green and blue data from three workspaces/spectra? By comparison the colour plots now have a single value per pixel which is then looked up in a colour scale. It would be a good way to present several linked values, such as amplitude, phase and relaxation rate of a signal, versus parameters like magnetic field or temperature.
