Description
I'm using IPython interactive, including a from pylab import *
A plot I was trying to make was breaking my renderer. I simplified the problem to the following line:
plot(array([179.5, 175.]),'o')
The data points get plotted, but the ytick labels don't finish rendering. The error messages (copied at the end of this message) get written to the terminal, and get re-written each time I try to do anything, until the figure is cleared. The choice of marker doesn't affect the behavior. There is some flexibility in choice of data values, but if I increase the first element to 179.6, I get no error.
Additional weirdness: This is only a problem when rcParams['font.size'] is set to 12. The problem goes away if I choose a smaller or larger font.
As I normally don't use 12pt font, I've never noticed this problem before, but I've verified that it also happens with my installation using python2.7 (which appears to be using the same version of matplotlib anyhow). Does anyone have an idea what might be going on?
Thanks!
Here are some details of my setup:
python3.4
IPython v3.4.4
Matplotlib v1.5.1
Using matplotlib backend: MacOSX
numpy v1.11.0
OS X (10.10.5)
Installed with MacPorts
Here is the error message I get:
