Hello How can I set decade on log x axis to be equal length to decade on log y axis (physically)? If I make: ax.set_xscale("log") ax.set_yscale("log") ax.set_aspect(1) I get it all wrong, the units are equal, not decades!! I need the same effect as I get in Gnuplot - the square decades: set l

Re: [Matplotlib-users] using MPL and ipython "run" command

Try to put plt.draw() before plt.show(). My guess is that what show() does is to create figure windows, and in most cases it does not redraw the figure (Tk backend is always an exception). So, this may not be a bug. But I hope some who knows well about the backends clarify this. Regards, -JJ

John, I've seen this problem happen before with someone else; the person's X11 installation for some reason included the file libfreetype.6.3.dylib but not librfreetype.6.3.dylib. Did you install X11 before or after installing the Xcode development tools? Also, if you had to install X11 yourself,
