mac安装matplotlib,解决报错,并设置显示中文

安装matplotlib, 

pip install matplotlib==2.2.2

1. 终端输入: 

echo  backend: TkAgg > ~/.matplotlib/matplotlibrc

解决以下报错:

Python is not installed as a framework. The Mac OS X backend will not be abl.....

2. 设置中文字体:

下载中文字体雅黑字体,安装mac安装字体参考,将字体复制到.../matplotlib/mpl-data/fonts/ttf

3.重新加载字体库

from matplotlib.font_manager import _rebuild

_rebuild()

4. 查看新加入matplotlib的字体,我这里显示的是   Microsoft YaHei

import matplotlib.font_manager

a = sorted([f.name for f in matplotlib.font_manager.fontManager.ttflist])

for i in a:
    print(i)

5. 测试一下:

        from matplotlib import pyplot as plt

        data_dict = {
            "name_data": ["延边", "杭州", "深圳", "上海", "未知"], "val_data": [54, 54, 90, 279, 594]}

        plt.rcParams['font.sans-serif'] = ['Microsoft YaHei']  # 用来正常显示中文标签
        plt.rcParams['axes.unicode_minus'] = False

        plt.figure(figsize=(20, 8), dpi=100)
        plt.plot(data_dict["name_data"], data_dict["val_data"])
        plt.savefig("./test.png")
        plt.close()

完美
