boxplot fontsize argument only works on x axis (and not on y axis) #15108
Description
Code Sample
import pandas as pd df = pd.DataFrame({"a": [0, 0, 0, 1, 1, 1], "b": [1, 2, 3, 4, 5, 6]}) df.boxplot("b", by="a", fontsize=20)Problem description
The fontsize is only applied to the x axis and not to the y axis tick labels (see figure).
Expected Output
IMO this argument should change the font size of both axes tick labels. Side note: I've tried to use the new plot API, but I couldn't get the output to match the one shown above using df.plot.box (I couldn't figure out how to set the variable to plot in the first place - probably this only works on Series and not on DataFrames).
Output of pd.show_versions()
