Matplotlib默认情况下无法正确显示负号,但可以使用以下方法来解决这个问题。首先,我们可以导入mpl模块并设置正常显示符号。具体代码如下:
```python
from pylab import mpl
mpl.rcParams["axes.unicode_minus"] = False
```
这段代码将会解决Matplotlib无法显示负号的问题。通过设置`mpl.rcParams["axes.unicode_minus"] = False`,我们告诉Matplotlib使用Unicode编码来显示负号。这样就可以正确显示负号了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
