在matplotlib中错误的乳胶渲染

Question

使用python 2.7.12（在Ubuntu 16.04上）和matplotlib 1.5.2，以下代码呈现错误：

from matplotlib.pyplot import *
plot([1,2],[1,1])
xlabel(r"$\beta+1$")
title(r'$\alpha > \beta$')
show()

xlabel呈现为$\partial i\Delta$，标题呈现为$\rightharpoonup\Upsilon\partial$，如您所见：

我的乳胶安装功能正常。知道问题是什么吗？

您可以在User's Guide中阅读有关matplotlibrc文件的信息：

# [...] When text.usetex is False,
# font.family may also be one or more concrete font names.

因此，您应该使用具体的font.family属性，或者只需将text.usetex文件中的True参数更改为matplotlibrc。

#text.usetex     : False  # use latex for all text handling. The following fonts
                          # are supported through the usual rc parameter settings:
                          # new century schoolbook, bookman, times, palatino,
                          # zapf chancery, charter, serif, sans-serif, helvetica,
                          # avant garde, courier, monospace, computer modern roman,
                          # computer modern sans serif, computer modern typewriter
                          # If another font is desired which can loaded using the
                          # LaTeX \usepackage command, please inquire at the
