【问题描述】：
我将 matplotlibrc 参数文件中的字体样式设置为已安装的 Helvetica（无衬线），并将 text.usetex 设置为“true”，但轴字体使用衬线字体。我的 matplotlibrc 参数文件如下：

如何获取坐标轴字体以使用 Helvetica sans？
更新
我尝试使用代码：
plt.rcParams['font.family'] = 'Helvetica'
但这是我得到的错误：
/usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1236: UserWarning: findfont: Font family ['Helvetica'] not found. Falling back to Bitstream Vera Sans
(prop.get_family(), self.defaultFamily[fontext]))
/usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1246: UserWarning: findfont: Could not match :family=Bitstream Vera Sans:style=normal:variant=normal:weight=normal:stretch=normal:size=medium. Returning /usr/share/matplotlib/mpl-data/fonts/ttf/cmb10.ttf

【问题讨论】：
-
我在 matplotlibrc 文件中注意到的一件事：
font.sans-serif : Helvetica, Arial, Bitstream Vera Sans,.......应该只是一种字体类型，即font.sans-serif : Helvetica -
另外，
true和false不应该大写吗？ -
如果字体不可用，我相信字体会在剩余字体中循环。
-
您是否正在使用任何其他可能会覆盖您的默认 matplotlibrc 设置的包（例如
seaborn，或您自己正在导入的一些代码等）？ -
@JoeKington 不，我没有使用任何其他软件包。
