Seaborn: How to increase the font size of the labels on the axes?

问题

Here's how I plot the heat map:

sns.heatmap(table, annot=True, fmt='g', annot_kws={'size':24})

The thing is, size set only the font size of the numbers inside the heatmap. Which parameter I should use in annot_kws to set the font size of the labels on the axes?

Thanks

You cannot change those directly in the call to heatmap, but you can instruct matplotlib to change the font size either in plt.rcParams directly, or using a context manager:

uniform_data = np.random.rand(10, 12)
plt.figure()
with plt.style.context({'axes.labelsize':24,
                        'xtick.labelsize':8,
                        'ytick.labelsize':16}):
    ax = sns.heatmap(uniform_data, annot=True, fmt='.1f', annot_kws={'size':6})
    ax.set_xlabel('x label')
