So I can do:
plot([1,2,3], [1,4,9], marker='+')
and it'll draw 3 points each with a + marker.
What I'd really like to do is
plot([1,2,3], [1,4,9], markerlist=['A', 'B', 'C'])
and have it draw the first point with a rendered
letter 'A', the second with a 'B', and the third with
1) Not sure how to draw a letter as my marker - are
markers limited to those in the marker list? Is that
2) And is it possible to have a different marker for each
point in a dataset, specified by a vector? I guess I
could draw a separate plot for each point, but that's
an enormous kludge.
