[Matplotlib-users] Plotting Multiple Curves on Same Axes; Save as .jpg

[Rich Shepard]

   I've looked at all the docs I can find on the matplotlib web site without
finding the answers to two questions. Pointers to references are greatly
appreciated.

   1)  I want to plot a series of curves on the same set of axes. For
example, shoulder- and trapezoidal curves:

         _______          __________          _______
        |       \        /          \        /
        |        \      /            \      /
        |         \    /              \    /
        |          \  /                \  /
        |           \/                  \/
        |           /\                  /\
        |          /  \                /  \
        |         /    \              /    \
        |        /      \            /      \
        |_______/________\__________/________\_______

With labels and text, of course. Each curve represents values in a separate
row of the database table.

   How do I specify that subsequent curves are to be plotted on the same axes
as the first one?

   2)  When each plot is created I want to save it as a .jpg file so it can
be included in a ReportLab report. Do I specify the filename and extension
in the save() command, or is there a different way?
