Daryl,
ok, much clearer now - what you want is for your text to not be
cut-off the way it is in the 8x8 80dpi plot? In other words,
there's not enough space left in the figure for the axis labels
to be completely displayed.
At the moment, I don't think there's a simple way of doing it,
and the quick way I find myself doing is by adjusting the subplot
parameters using:
plt.subplots_adjust(left=..., bottom=...)
I'm almost certain that one *can* write a function to do this
pro grammatically (without having to hand tweak anything), by
looking at say, the .get_window_extent() but I haven't found the
time to scratch that itch, yet.
If someone wants to beat me to it, here's the sort of thing that
you can do:
def show_labels_by_shrinking(ax):
" adjust subplot parameters to fit the yaxis label"
f = ax.figure
textwidth = ax.yaxis.get_label().get_window_extent().width
labelwidth = max([lab.get_window_extent().width for lab in
ax.get_yticklabels()])
plt.subplots_adjust(left=(textwidth+labelwidth+3*ax.yaxis.labelpad)/f.get_window_extent().width)
# the 3 *ax.yaxis.labelpad is just a fudge factor for now, need
# to look into the sourcecode to figure out what the
# appropriate placement is normally, to know how to adjust
# properly
ax.set_ylabel('foo')
show_labels_by_shrinking(ax)
ax.set_ylabel("a\nmulti\nline\nexample")
show_labels_by_shrinking(ax)
best,
