There is a parameter in the function corresponding to legend; by default it is True

df.plot(legend=False)

Following is the definition of the .plot() method

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)

In order to remove a legend that has once been drawn, use

plt.gca().get_legend().remove()

assuming that you have imported matplotlib.pyplot as plt or

ax.get_legend().remove()

if ax is the axes where the legend resides.

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

df.plot(legend=False)
