Won't use a font although it can be found by the FontManager #3590
Description
Hi,
I was asked to file an Issue here on github, although I'm not sure if the problem is not in front of my PC... .
from pylab import *
from math import sin
rc('text', usetex = False)
la = matplotlib.font_manager.FontManager()
lu = matplotlib.font_manager.FontProperties(family = 'Heuristica')
print la.findfont(lu)
x = np.arange(0,5,0.1)
y = map(sin,x)
title('This is an unnecessary title', family = 'Heuristica')
plot(x,y)
show()As a result I get (besides a graph using an unwanted font):
C:\Windows\Fonts\Heuristica-Regular.otf C:\Python27\lib\site-packages\matplotlib\font_manager.py:1279: UserWarning: findfont: Font family ['Heuristica'] not found. Falling back to Bitstream Vera Sans (prop.get_family(), self.defaultFamily[fontext]))
If I add Heuristica on first spot of the serif-font-Types this will also not work, (i. e. font.serif : Heuristica, Bitstream Vera Serif)
I am using matplotlib 1.4.0 and Python 2.7.6, I asked this question on StackOverflow first

When you add new fonts to your system, you need to delete your fontList.cache file in order for matplotlib to find them.
The reason it works on lines 4/5 in your example is because you are creating a FontManager from scratch (which goes out to the filesystem and hunts down all the fonts). Internally, when matplotlib later does its own font lookup, it is using a FontManager that has been loaded from a cache on disk in the fontList.cache file.
Long term, we have plans to switch to using the font lookup mechanisms of the OS to get around this problem, (see MEP14), but in the meantime, you'll need to remove the fontList.cache file everytime you want matplotlib to discover new fonts.

Perfect! That trick did it. the fontList.cache is located at Home/.matplotlib

Blah, should have known that...

maybe also /tmp/xdgcache/matplotlib directory in 1.4.2 version

The matplotlib font cache can be found here:
Win7: %userprofile%\.matplotlib\
Ubuntu: ~/.cache/matplotlib
Update soundfield transform figures to illustrate rE
ATK: Update Intro-to-the-ATK & imaging figures

This is closed so apologies for raising it again. This is not working for me, matplotlib version: 1.5.1.
