FontManager.__init__ goes through all the files in the cache to determine if they still exist and refreshes the cache if it finds one missing. Your patc

[matplotlib-devel] patch: step function plotting

Hi, I have created a patch against latest svn that adds a function step to the axes class to plot step-functions ;-) It's really simple but nice ... Any interest in adding this? Manuel <>Index: axes.py === --- axes.py (revision

Manuel, We do plots like this all the time. One thing we've found that's nice to have is a keyword that controls when the increase in y happens. We use a step style keyword that can be 'pre' (go up then right), 'post' (go right then up), and 'mid' (right 0.5, up, right 0.5). Regarding your

Hmm... I'm not readily able to reproduce this here. What are you setting in matplotlibrc (or in your plot?) Also, if you delete the font cache (which is now ~/.matplotlib/fontManager.cache), does that help? (Might be a useful data point -- not suggesting it as a solution.) Cheers, Mike Rob

Mike, Rob, One of the changes I made was to cause the afmdict to be generated automatically at the start rather than on demand. The problem you are having seems related to afm fonts, so I suspect this is it. What is your rcParams['pdf.use14corefonts'] setting? Please try reversing it, and se

Rob, Mike, What this implies to me is that either there is a problem with the code that is generating afmdict (and I did not change that code, I just caused it to be invoked when the fontManager instance is created.), or there is a problem with some .afm files on Rob's machine. I really don't

mpl hates my guts today. I'm developing an application for work and need to plot some spectra on a logscale. I can recreate my problem with embedding_in_qt4, by replacing MyDynamicMplCanvas.compute_initial_figure with this: def compute_initial_figure(self): self.axes.plot([0, 1, 2,
