I don't know what dumb thing I'm going but I can't seem to plot
2 horizontal lines on the same plot!!!
Why does this snippet give a *BLANK* plot when I run it?
(Either line separately seems to be ok!?!?)
import pylab
x1 = pylab.arange(-10, 10, 0.01)
x2 = pylab.arange( 0, 10, 0.01)
f1 = [0 for

meaning you run a series of commands in order and it usually does the
right thing, rather than passing the results of one function into
another (in general).
Did you not get an exception when you ran your example?

Thank you very
