title: how to increase the size of Jupyter notebook plot
body: <p>Using the calmap package I create a heatmap calendar but I would like to know how to increase the font or the size of the plot.</p>
  
  <pre><code>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)
  </code></pre>
