how to display a title on a calendar heatmap using calplot?

I am trying to save a calplot image but I can't seem to display the title. Following the documentation, I need to use the property: suptitle.

import calplot
import pylab
import numpy as np; np.random.seed(sum(map(ord, 'calplot')))
import pandas as pd
all_days = pd.date_range('1/1/2019', periods=730, freq='D')
days = np.random.choice(all_days, 500)
events = pd.Series(np.random.randn(len(days)), index=days)
calplot.calplot(
    events, 
    figsize=(20,4),
    suptitle='lorem ipsum',
    cmap='Spectral_r',
    )
pylab.savefig('foo.png')

Above is the minimal code found in the documentation. I am using pylab to save the image on my drive Calplot image

I can barely notice the title. How can I show the title? I am using Windows and Continuum Anaconda as stack

Solution

  • Increase the font size

    fontsize=20


import calplot
import pylab
import numpy as np; np.random.seed(sum(map(ord, 'calplot')))
import pandas as pd
all_days = pd.date_range('1/1/2019', periods=730, freq='D')
days = np.random.choice(all_days, 500)
events = pd.Series(np.random.randn(len(days)), index=days)

fig = calplot.calplot(
    events, 
    figsize=(20,4),
    cmap='Spectral_r',
    )
fig.suptitle('lorem ipsum', fontsize=20)
pylab.savefig('foo.png')

    Updated with fig defined
