在python中使用pandas库并使用

on a dataframe, how do I display the plot without a legend?
在数据框上，如何显示没有图例的图？
采纳答案by Nipun Batra
There is a parameter in the function corresponding to legend; by default it is True
图例对应的函数中有一个参数；默认情况下它是 True
df.plot(legend=False)
Following is the definition of the .plot()method
下面是.plot()方法的定义
Definition: df.plot(frame=None, x=None, y=None, subplots=False, sharex=True, sharey=False, use_index=True, figsize=None, grid=None, legend=True, rot=None, ax=None, style=None, title=None, xlim=None, ylim=None, logx=False, logy=False, xticks=None, yticks=None, kind='line', sort_columns=False, fontsize=None, secondary_y=False, **kwds)
定义：df.plot(frame=None, x=None, y=None, subplots=False, sharex=True, sharey=False, use_index=True, figsize=None, grid=None, legend=True, rot=None, ax=None, style=None, title=None, xlim=None, ylim=None, logx=False, logy=False, xticks=None, yticks=None, kind='line', sort_columns=False, fontsize=None, secondary_y=False, **kwds)
回答by ImportanceOfBeingErnest
In order to remove a legend that has once been drawn, use
为了删除曾经绘制的图例，请使用
plt.gca().get_legend().remove()
assuming that you have imported matplotlib.pyplot as pltor
假设你已经import编辑matplotlib.pyplot as plt或
ax.get_legend().remove()
if axis the axes where the legend resides.
ifax是图例所在的轴。
Alternatively, see Nipun Batras answer if there is some choice to turn the legend off from the beginning in which case one can simply use
或者，如果有一些选择从一开始就关闭图例，请参阅 Nipun Batras 回答，在这种情况下，可以简单地使用
df.plot(legend=False)
