Louis,
This is standard num* array behavior: arrays are mutable, and MPL is
not making copies of them when you plot, which is a good thing.
by the way, slices of arrays are references too, which is different
than python lists, so it can be surprising, but also useful
# 1st Plot .................
x[0]= 1.0
y[0]= 1.0
x[1]=-1.0
y[1]=-1.0
a.plot(x,y)
# 2nd Plot .................
now you need copies. You can make brand new ones, or use the copy()
method:
x = x.copy()
y = y.copy()
you could also pass a copy into the plot method:
a.plot(x.copy(), y.copy())
which is perhaps the behavior you were expecting.

Thanks, Chris. I sort of figured this out, but you put it clearer and I
like the copy suggestion. I'll use it. It sure drove me nuts for a
while. :-)
