[Tutor] plotting in python

[stm atoc]

For previous script that I have written, I had trouble having one plot
for all data at the same time and I could see two line for Conc[0] and
Conc[1] separately. Now, even I modified Conc = a[1:, N+1:] to  Conc =
a[0:, N+1:], still one plot is created...which is pretty good and no
error!

Thank you so much,
Sue
