Eric recently updated LineCollection to inherit from ScalarMappable
(in mpl 0.87.3) which means you can pass it a colormap instance.
Perhaps we should update the wiki example to reflect this. I'm not at
all opposed to making a helper function like scatter to plot
parametric lines with colormaps, but I don't think "plot" is the right
vehicle, since it returns a Line2d, not a LineCollection, and since it
is already heavily overloaded. parplot?

I think having a helper function is a good idea. Not only does it
help the newcomer, but it also allows the oldtimer to write shorter and
more readable code.
I find that "parplot" is not a great name for such a function, but I
cannot think of a better one. Maybe the list will have better ideas.

Talking to a friend we came up with a name like "pathcolor", or
"pathplot".

How about 'plots'? (i.e., a bunch of plot commands)
Perhaps this could also be the function that loops through multiple lines. For example in matlab you can do
plot (x, y)
plot (x', y')
to plot out a grid -- the columns (or is it the rows..) are looped through inside the plot command. Is this the sort of thing you have in mind for the new 'parplot' command?
