Matplotlib默认使用的是英文字体,不支持中文。解决方法有两种:
1. 修改默认字体
在Matplotlib中,可以通过修改默认字体来支持中文显示。具体操作如下:
```python
import matplotlib.pyplot as plt
plt.rcParams['font.family'] = 'SimHei' # 设置中文显示
plt.plot([1,2,3],[4,5,6])
plt.show()
```
SimHei是Windows系统中自带的中文字体,也可以替换成其他支持中文的字体名称。
2. 使用中文字体
如果不想修改默认字体,可以使用支持中文的字体来显示中文,具体操作如下:
```python
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
font = FontProperties(fname=r"C:\Windows\Fonts\simhei.ttf", size=14) # 设置字体
plt.plot([1,2,3],[4,5,6])
plt.title('中文标题', fontproperties=font) # 使用中文字体显示标题
plt.xlabel('横轴', fontproperties=font) # 使用中文字体显示横轴标签
plt.ylabel('纵轴', fontproperties=font) # 使用中文字体显示纵轴标签
plt.show()
```
需要先下载支持中文的字体文件,然后通过FontProperties来加载字体文件并设置字体大小。然后在图表中通过fontproperties参数来指定要使用的字体。
