plt.rcParams['axes.unicode_minus']= False

This line of code is used to remove the minus sign from the axis labels and tick marks in a matplotlib plot. By default, matplotlib uses a Unicode minus sign (U+2212) instead of a regular minus sign (-) for negative numbers on the axis. The above code changes this behavior and uses a regular minus sign instead. This can make the plots easier to read and understand for some viewers.

plt.rcParams['axes.unicode_minus'] = False

这行代码的作用是解决在 matplotlib 中使用负号时出现的乱码问题。默认情况下，matplotlib 会将负号替换为一个特殊的 Unicode 字符，但有些字体不支持这个字符，就会出现乱码。通过将 `plt.rcParams['axes.unicode_minus']` 设置为 `False`，就可以使用正常的 ASCII 负号代替 Unicode 负号，避免出现乱码。

plt.rcParams['axes.unicode_minus']=False

This line of code is used in Python's Matplotlib library to disable the rendering of the negative sign as a hyphen (-) in plots and graphs. By default, Matplotlib uses a hyphen to represent negative numbers, but this can be confusing in some cases, especially when working with math or financial data. The `plt.rcParams['axes.unicode_minus']=False` command changes the default behavior so that negative signs are displayed as actual minus signs (−), which is more visually consistent and easier to read.
