Difference between pd.df.plot.box() and pd.df.boxplot()

Question

Why pandas has two funcitons for Boxplot : pandas.DataFrame.plot.box() and pandas.DataFrame.boxplot() ?

df = pd.DataFrame(np.random.rand(10, 5), columns=['A', 'B', 'C', 'D', 'E'])
df.plot.box()

df.boxplot()

Answer 1

Both return a 'matplotlib.axes._subplots.AxesSubplot' object. Obviously, they are calling upon different parts of the pandas library to execute.

One of the consequences of this is that the pandas.DataFrame.plot.box() method uses the FramePlotMethods class where "grid = None" and pandas.DataFrame.boxplot() has "grid = True" by default. You'll notice this in the background lines in your two charts.

Additionally, .boxplot() can't be used on a Series, whereas .plot's can.
