You will probably want to add axes explicitly (not with subplot), e.g.
fig.add_axes([.1,.1,.71,.8])
specifies the coordinates of one corner and the width and height (in
proportions of the figure size). When doing this explicitly, you will
probably need to do some extra adjustments to fit the
I use a scatterplot with enough points to overlap into a line. Works
best with alpha=0.5 or thereabouts; I generally overplot with a dashed
B&W line to make the legend understandable.
Probability that there is a more elegant way: high.

My department is practicing presenting-science-for-the-general-public,

There's a gallery example doing that in general, making pie-charts out
of the markers:

When you mentioned it, so was I. From axes.py:

"""

You'd always have to specify the domain, so
plot(map(lambda x:x**2, range(1,10)))
shouldn't be much longer than the minimal command.

To zoom in on the relevant section of a colorbar -- I convinced myself
once that I'd need an auxiliary function to define a new cdict that
covers only the current section of the original cdict. (and then
define a new colorbar from the cdict, and maybe do a little norming of
the data).

But this example doesn't solve the problem I was thinking of: it shows
lots of colors in the colorbar that aren't used in the plot.

I got curious and looked for the grid command in matplotlib/axes.py.
Looks like an inherited-from-Matlab thing. In the cla (clear axis)
function of the Axes class:
self._gridOn = rcParams['axes.grid']
#...
self.grid(self._gridOn)
and grid() passes its argument on to

You can make the values the independent axis of the histogram.

Would it be workable for the default to be proportional to the size of the
array passed in? (suggested only because I do that myself, when deciding how
coarse an investigative plot I can get away with.)

ly ever use show() at all, but rather

If that doesn't work for you, the experts probably need a more precise
bug report to figure out what would.

And if you have mutually prime numbers of colors,
linestyles, widths, you can automatically generate
more distinct lines than I can distinguish... If there's any
wxcuse for treating them as a series, I replot
when I know how many I have, and space the
colors through a colorbar.

You can plot them all individually; e.g.
rec = ([1,2,.5], [0.5, 3, 1.1], [5, 7, .2])
for r in rec:

Any current transforms examples? The transforms docs suggest looking
in /units for transforms examples; the current matplotlib examples
has /units without transforms. (I want something a bit more detailed
than the offset.)
If the transforms are currently too much in flux, I'll do something
