After using Multiwfn to plot TDOS/PDOS/OPDOS map as illustrated in Section 4.10 of Multiwfn manual, in the post-process menu you can use option "3 Export curve and line data to plain text file in current folder" to export curve data to .txt file, then you can import it into Origin. The meaning of each column in this file is clearly shown on screen after selecting that option.
I don't know where you want to set subscript and superscripts. If you hope to use subscript or superscript style for some texts in legends of DOS map, it is not supported in Multiwfn.
Best regards,
