Dear Mathgroup, I am a new mathetica user and learning to plot my band diagram, i.e., energy E vs wave vector k. Assumed that E(k, y) and y is a series of integers. I use the following function: Plot[k^2+y, {k, -Pi, Pi}, {y, -3, 3}] and would like to plot "a series of" bands in a 2D plot, however, it did not work. Anybody can help me out? Thanks, Regards, Po-Wen
