I'm making a strip chart widget (which I plan to make publicly

So...can I convince the automatic sizer to always show the full X
(time)
axis annotations and put all the variable sizing into the data
area? Or
do I have to manually set them somehow?
As far as I know, there's nothing to automatically resize the
padding around the the axes. (The manual way to do it is to call
`fig.subplots_adjust`). I wrote a helper script (attached below) to
adjust the layout so that there's a specified amount of padding
around the axes.
Unfortunately, this resizer doesn't function correctly when using
the GTK backend. It apparently works fine with TkAgg, MacOSX, and
Qt4Agg backends.
Fortunately I'm using TkAgg. I'm sorry (though not surprised) I'll
have to size it manually (especially since users of my application can
change the font size), but I very much appreciate the code.
Also, is there a way from my software (not a .matplotlibrc file) to
globally make the default background color white for axis annotation
areas? Right now the background is gray for annotations and while for
plot area and I'd prefer it was all white.
Just set plt.rc('figure', facecolor='w') in your code (assuming
you've imported matplotlib.pyplot as plt).
Perfect. Thanks!
<tight_layout.py>
Usage note: Since it sounds like you're not creating subplots, you
can just use the `tight_borders` function, instead of the
`tight_layout` function; the later requires two redraws while the
first requires only one.
Thank you very much for the advice and script!
I do plan to support strip charts stacked atop each other (all using
the same time range, with tick labels only along the bottom x axis),
which I suspect will need subplots (unless there is now a better way)
but so far all I have is multiple lines (including dynamic and static
-- e.g. to display limits) one one plot.
