我试图用标签使用gettext的_（“标签”）构造来显示matplotlib图。试着创建一个最小的例子，我想出了下面的python代码。它贯穿于NULLTranslations（）这样的罚款：matplotlib在gtk窗口中使用i18n（gettext）支持
蟒蛇mpl_i18n_test.py
但是当我切换到日本，我什么也没得到，但小方块中的情节 - 尽管在命令行中，译文看起来不错：
LANG = ja_JP.utf8蟒蛇mpl_i18n_test.py
这里是文件mpl_i18n_test.py 注意，这需要安装蒙娜丽莎-沦字体和各种Python模块：PyGTK的，numpy的，matplotlib ，gettext和polib
所以我的问题：是否有一些技巧让matplotlib和gettext一起玩呢？我在这里错过了很明显的东西吗谢谢。
