Re: [Matplotlib-users] Plotting from datafile

[Sayan C. <say...@gm...>]

Thank you very much!!...'plt.cla()' worked!!

One slight hiccup. Could you please tell me how to fix up the Y grid? I
mean I want every plot to have scale from 0 to 15 (say), not that some will
have -5 to 10 and some will have 5 to 20.Is it possible?...it's
absolutely necessary for the concerned simulation.
