Auto adjust font size in seaborn heatmap

Question

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=         


        

Answer 1

To adjust the font size of seaborn heatmap, there are different methods

import seaborn as sns # for data visualization
flight = sns.load_dataset('flights') # load flights datset from GitHub seaborn repository

# reshape flights dataeset in proper format to create seaborn heatmap
flights_df = flight.pivot('month', 'year', 'passengers') 

sns.heatmap(flights_df) # create seaborn heatmap

sns.set(font_scale=2) # font size 2

Output >>>

the sns.set(font_scale=2) # font size 2 set size for all seaborn graph labels that's reason follow another method if you like

import seaborn as sns # for data visualization
import matplotlib.pyplot as plt # for data visualization

flight = sns.load_dataset('flights') # load flights datset from GitHub seaborn repository

# reshape flights dataeset in proper format to create seaborn heatmap
flights_df = flight.pivot('month', 'year', 'passengers') 

sns.heatmap(flights_df) # create seaborn heatmap


plt.title('Heatmap of Flighr Dataset', fontsize = 20) # title with fontsize 20
plt.xlabel('Years', fontsize = 15) # x-axis label with fontsize 15
plt.ylabel('Monthes', fontsize = 15) # y-axis label with fontsize 15

plt.show()

Output >>>
