Dear Johnny, Yes, you can superimpose more plots on top of each other, by providing axes returned by one plot as an argument to the next one. If you want to do something with spin you probably should include spin-orbit coupling, yes. Best, Anton On Sun, Nov 22, 2015 at 10:22 AM, T.C. Wu <tcwu@connect.ust.hk> wrote:

Dear Kwant developers and users,

For the plot of the graphene wavefunction as illustrated in http://kwant-project.org/doc/1.0/tutorial/tutorial6, is it possible to show the distribution of the spin in the same plot? Should I include the spin orbital coupling? Thanks.

Best, Johnny
