If there is a case where, there are several lines that have to be plotted on the same graph from a data source (array, Dataframe, CSV file, etc.), then it becomes time-consuming to separately plot the lines using matplotlib.pyplot.plot() function. So, in such cases, you can use a ...
为了解决这个问题，你需要计算每一列的百分比，然后把它标出来。

首先，没有必要分配y1和y2对象，因为以后永远不会使用它们。另外，legend=True是默认值。
