sns heatmap yticklabel rotate code example

Example 1: seaborn heatmap x labels horizontal

# This sets the yticks "upright" with 0, as opposed to sideways with 90.
plt.yticks(rotation=0)

Example 2: seaborn heatmap xlabel rotation

plt.figure(figsize=(10,10))
g = sns.heatmap(
    by_sport, 
    square=True, # make cells square
    cbar_kws={'fraction' : 0.01}, # shrink colour bar
    cmap='OrRd', # use orange/red colour map
    linewidth=1 # space between cells
)
