Here's a legend function which allows you to specify loc='outer right'. The
part for 'outer left' doesn't work. It basically wrappes the
pylab.legendmethod, it rescales the plot and sets the location of the
legend to
coordinates outside of the current axes.
def legend(*args, **kwargs):
"""
Overwrites the pylab legend function.
It adds another location identfier 'outer right'
which locates the legend on the right side of the plot
The args and kwargs are forwarded to the pylab legend function
"""
if kwargs.has_key('loc'):
loc = kwargs['loc']
loc = loc.split()
if loc[0] == 'outer':
# make a legend with out the location
# remove the location setting from the kwargs
kwargs.pop('loc')
leg = pylab.legend(loc=(0,0), *args, **kwargs)
frame = leg.get_frame()
currentAxes = pylab.gca()
currentAxesPos = currentAxes.get_position()
# scale plot by the part which is taken by the legend
plotScaling = frame.get_width()/currentAxesPos[2]
if loc[1] == 'right':
# scale the plot
currentAxes.set_position((currentAxesPos[0],
currentAxesPos[1],
currentAxesPos[2] *
(1-plotScaling),
currentAxesPos[3]))
# set x and y coordinates of legend
leg._loc = (1 + leg.axespad, 1 - frame.get_height())
# doesn't work
#if loc[1] == 'left':
# # scale the plot
# currentAxes.set_position((currentAxesPos[0] +
frame.get_width(),
# currentAxesPos[1],
# currentAxesPos[2] *
(1-plotScaling),
# currentAxesPos[3]))
# # set x and y coordinates of legend
# leg._loc = (1 -.05 - leg.axespad - frame.get_width(), 1 -
frame.get_height())
pylab.draw_if_interactive()
return leg
return pylab.legend(*args, **kwargs)
Cheers! Bernhard
