Newbie question about plotting multiple lines

There are a lot of ways to do this, I dont know them

    > all. Here are a few to get you started:

These are all good suggestions, and the right way 99% of the time. I
just want to point out that if you need to plot hundreds or thousands
of separate lines, calling plot over and over again is not the most
efficient strategy, since a new matplotlib.lines.Line2D object must be
created each time. For these cases it is best to use a line
collection (matplotlib.collections.LineCollection). You can find an
example of their use in the plotmap demo -, where line
collections are used to draw the geographic borders over a colormap.
