The function that you found, kwant.wraparound.plot_2d_bands, is the only "intelligent" band structure plotting routine that exists in Kwant currently. > 2) If it is not, could I extract data shown from > kwant.wraparound.plot_2d_bands? There’s no way to extract local variables from a Python function call, but you can look at the source code of plot_2d_bands [1] and use it to your liking. For example, you could simply copy that function into a module of your own, and save the data that you find useful.
