sumo-dosplot: superimposing multiple DOS plots

[Kardimum23]

I have two separate vasprun.xml files and wish to superimpose their DOS plots, but I am unsure how to go about doing so. Any help is highly appreciated.

Hi,
this functionality is not currently supported in Sumo.

Sumo DOS plots default to showing contributions from orbitals, so it is likely that a plot of several superimposed PDOS would be totally illegible. Overlaying TDOS plots would be more reasonable, but care should be taken with the energy reference levels.

Sumo does write out DOS data to plain-text files. You should find those files fairly straightforward to import into e.g. GNUPlot, Origin, Grace or a Python script if you would like to make a custom plot. I think some of our users do this routinely.

If/when we improve the Sumo Python API it might become easier to suggest a short script for such things. We'll keep it in mind!
