plot help


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
