Matplotlib 3.0 Cookbook

How to do it...

Here are the steps to plot the required graphs. We will plot three figures, one after the other. The first figure will have three plots, the second figure one plot, and the third figure two plots:

1. Define the first figure object and define the axes objects on which we will plot the seaborn plots:

fig, (ax1, ax2, ax3) = plt.subplots(1,3, figsize=(15,5))

2. Plot a heatmap with a predefined colormap:

sns.heatmap(sales, annot=True, fmt='.0f', linewidths=.5,             cmap="YlGnBu", ax=ax1)ax1.set_title('Using pre-defined Colorbar')

3. Plot a heatmap with a colormap centered at a specific value:

sns.heatmap(sales, annot=True, fmt='.0f',linewidths=.5, robust=True,            cmap="YlGnBu", center=sales.loc[3, 'Cookies'],  yticklabels=False, ax=ax2) ...
