Description

Axis ratio of plots are distorted when displayed in dock, while they are properly displayed in-line. I cannot recall when the issue started, I believe it was a few days ago.

Steps to Reproduce

1. import pandas and create data frame
2. plot the data in dock

import pandas as pd

cars = {'Brand': ['Honda Civic', 'Toyota Corolla', 'Ford Focus', 'Audi A4'],
        'Price': [22000, 25000, 27000, 35000]
        }

df = pd.DataFrame(cars, columns=['Brand', 'Price'])

df.plot.bar()

3. go to Hydrogen Settings, select 'View output int the dock by default'
4. re-plot data with output in dock
