Hello everyone,
I've just changed my computer from a old core 2 duo on windows Xp to a
intel Xeon with 12 Gb Ram. I've installed matplotlib but I plot a graph
it's about 10 times slower than windows Xp to pan the axis or move the
graph. Even if I'm plotting something very simple like that:

Actually I want to try to plot something like this picture:

Is it possible to have automaticaly more than 3 colors when Iplot a graph?
When I plot it put the first in blue the second in green the third in red

I don't manage to put the color of my plot in the argument' list function.
Example:

even if I put function(" 'r' ") it doesn't work.
Any idea?

I have a basic problem (I think)
I try to fit some data with this function

But it return an error:
fit = chebyshev.fit(T,R,3)

one in few weeks ( put different voltages on different devices then
measure many voltages
