AttributeError: 'AxesSubplot' object has no attribute 'get_axis_bgcolor'

When trying to run the sample code from the documentation

import numpy as np; np.random.seed(sum(map(ord, 'calmap')))
import pandas as pd
import calmap

all_days = pd.date_range('1/15/2014', periods=700, freq='D')
days = np.random.choice(all_days, 500)
events = pd.Series(np.random.randn(len(days)), index=days)

calmap.yearplot(events, year=2015)

I get the following error:

I just saw that it is the same issue as #19 and there already exists a PR for it #22
However, I propose to keep the issue for better search engine visibility
