How we can plot different optical properties (from PBE and other functional,say HSE) in a single file

[kcbhamu]

I am having a PBE directory with PBE calculations and another directory with HSE calculations. I want to plot optical properties for both cases in the same file. Let's say, absorption spectra of PBE and HSE are in the same file.
Is it possible?

We don't currently have the capability to overlay multiple plots, except for phonon band structures.
I think your best bet for now will be to use the absorption.dat files from Sumo with another plotting program.
