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.

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

这也是一个Matplotlib库中的设置，它用于解决在Matplotlib中生成图形时负号显示为方块的问题。当这个设置为True时，Matplotlib会将负号显示为Unicode中的负号（U+2212），但是在一些系统中不支持该字符，因此会出现方块。将这个设置为False时，Matplotlib会将负号显示为正常的ASCII字符“-”，解决了负号显示问题。

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.
