I am using the pymatgen Vasprun and BSPlotter classes to plot data from my vasprun.xml file after an HSE06 band structure calculation in VASP (using 0 weight kpoint method). I copied a non-hybrid functional calculation kpoint file (one with high symmetry points and labels, traditional band structure KPOINTS file) into the working directory after the run finished and have the kpoints_filename variable set in the get_band_structure call, but I can't get the kpoint labels on the plot. These labels are shown when I plot the non-hybrid functional band structure no problem. Any suggestions would be greatly appreciated!! Ive attached the script.
