when using seaborn heatmap, is there a way to auto-adjust the font size for it to fit exactly inside the squares? for example in: 

sns.heatmap(corrmat, vmin=corrmat.values.min(), vmax=1, square=True, cmap="YlGnBu", 
        linewidths=0.1, annot=True, annot_kws={"size":8})

here the size is set in "annot_kws".

You can also do:

sns.heatmap(corrmat, vmin=corrmat.values.min(), vmax=1, square=True, cmap="YlGnBu", linewidths=0.1, annot=True, annot_kws={"fontsize":8})
