Hi,
Are the edges of the rectangles returned by plt.bar() supposed to conform to the 'lines.solid_joinstyle' rcParam? If not, is there another method for specifying that joinstyle?
I have not been able to change the joinstyle using this method in versions 1.0.0 (linux, gtkagg and tkagg) or 1.0.1 (os x, tkagg). I can send a minimal example script if requested.
