Set the axis range in a boxplot

I'm working on this kaggle dataset on the EDA.

I´m working with some boxplot in pandas with this code: 

coupon_list[["CATALOG_PRICE","VALIDEND_MONTH"]].boxplot(by='VALIDEND_MONTH')

The problem I'm havaing here is that the y axes has a large scale and it hard to read the plot. Is there any way to limit the sixze of this axis? something similar to ylim ?

enter image description here

EDIT:

The dataset have outliers, adding the argument: 

showfliers=False

Seems to solve the issue.

It's weird since by default the Y axis is autoscaled, see the example below. Maybe you have some outliers in your data. Could you share more code?

import pandas as pd
import numpy as np

np.random.seed = 4

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
ax = df.boxplot()

standard box plot

Here is the same plot with outliers

# Generating some outliers
df.loc[0] = df.loc[0] * 10
ax = df.boxplot()

outliers

Could you try the showfliers option to plot the box without outliers? In this example the Y scale is back to [0-100].

ax = df.boxplot(showfliers=False)

showfliers : bool, optional (True) Show the outliers beyond the caps. matplotlib.axes.Axes.boxplot
