I’m developing a Web application and want to display a figure and its legend in different locations on the page. Which means I need to save the legend as a separate png file. Is this possible in Matplotlib in a more or less straightforward way?

This could work:
import pylab fig = pylab.figure() figlegend = pylab.figure(figsize=(3,2)) ax = fig.add_subplot(111) lines = ax.plot(range(10), pylab.randn(10), range(10), pylab.randn(10)) figlegend.legend(lines, ('one', 'two'), 'center') fig.show() figlegend.show() figlegend.savefig('legend.png')
