I doubt if you can obtain this from QE or not. The plot is essentially the -Im\epsilon_Q{\omega}^{-1}. You can have a look at the Yambo tutail for computing this object from QE DFT calculations.</div>

Yambo is a FORTRAN/C code for Many-Body calculations in solid state and molecular physics. Yambo relies on the Kohn-Sham wavefunctions generated by two DFT public codes: abinit, and PWscf.The code was originally developed in the Condensed Matter Theoretical
Group of the Physics Department at the University of Rome "Tor Vergata" by Andrea Marini. ...</div>
