今天使用matplotlib.pyplot绘制折线图时，出现**图表中文字不显示**的问题。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1pEXzAxMg_size_16_color_FFFFFF_t_70_pic_center]

同时会报错：**RuntimeWarning: Glyph 20540 missing from current font.  
font.set\_text(s, 0.0, flags=flags)**

## 解决方案 ##

需添加一行显示中文标签的代码：

plt.rcParams['font.sans-serif'] = ['SimHei']

字体选择：

<table> 
 <thead> 
  <tr> 
   <th>字体</th> 
   <th>对应名称</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>黑体</td> 
   <td>SimHei</td> 
  </tr> 
  <tr> 
   <td>微软雅黑</td> 
   <td>Microsoft YaHei</td> 
  </tr> 
  <tr> 
   <td>微软正黑体</td> 
   <td>Microsoft JhengHei</td> 
  </tr>
