axes scale factor not showing

Community matplotlib-users

Hi,

When matplotlib uses an axis multiplier, as in x-axis in the script
below, the scale factor is not positioned properly on the figure as is
shown in the attached picture. The 'x1e+30' in the bottom right corner
is clipped unless I enlarge the window.

--------------------
import Numeric, gtk
import matplotlib
matplotlib.use('GTK')
import matplotlib.figure, matplotlib.axes, matplotlib.backends.backend_gtk

# data
values = Numeric.array([-1e30, -1e30, 0,1,2,3,4,5,6,7,8,9], 'd')

# figure
figsize=(6,3)
figure = matplotlib.figure.Figure(figsize=figsize)
canvas = matplotlib.backends.backend_gtk.FigureCanvasGTK(figure)

axes = matplotlib.axes.Subplot(figure, 111)
figure.add_axes(axes)

axes.hist(values, bins=10)
axes.set_title('X-scale multiplier is hidden', fontsize=10)

# window to display
window = gtk.Window()
window.connect('destroy', gtk.main_quit)

window.add(canvas)
window.show_all()
gtk.main()
--------------------

I can use the axes position to work I guess but that seems rather
unsatisfactory as I'll have to figure out when it's being displayed or
not, font sizing and spacing blah blah blah.
Is there an easier way around this (or a fix?)? I'm using v0.90.0

Thanks
Tim

There is no current way to automate this easily -- Michael has done
some experimental work for autosizing the axes to make room for the
text on the svn trunk, but it is not complete. There is a parameter
that you can set in your matplotlibrc figure.subplot.bottom to make
the bottom of the axes higher by default, or you can manually change
this with

fig.subplots_adjust(bottom=0.2)

Hi John,

or you can manually change this with

fig.subplots_adjust(bottom=0.2)

Aha! I had been using rc('figure.subplot', bottom=0.2), but I was looking for a better way. Thanks!
