Hi Nafise, Please don't send repeated messages to the mailing list. Kwant figures return regular matplotlib figures, so you can use matplotlib functionality to annotate those figures. Please refer to matplotlib documentation on how to do that. Best, Anton On Thu, 21 Jan 2021 at 19:11, Nafise Nouri <nafise.nour@gmail.com> wrote:
