Dear all

I want to draw a contour plot of the first Brillouin zone and band structure along the path of high symmetry points by using Kwant. In Kwant, I know that "kwant.wraparound.plot_2d_bands" function shows the Brillouin zone in 3D. I read a kwant official documentary to find the information that I want, but I couldn't find the solution. 

My questions are as follows;
1) are there functions in kwant to draw 2D contour plot of the Brillouin zone and the band structure along the path of high symmetry points? 
2) If it is not, could I extract data shown from kwant.wraparound.plot_2d_bands?

Thank you for reading my email.   

Sincerely,
Daehan Park.
