how to understand Seaborn's heatmap annotation format?

Question

I am looking for a way to show \"0.0045\" as \"0.45%\" on seaboarn\'s heatmap by specifying the fmt keyword:

sns.heatmap(data, annot=Tr         


        

Answer 1

You can use .2% as the fmt to have your annotations displayed as percentages with 2 decimal places. Following is a minimum complete example. I have divided by 100 to have numbers in the range you are interested in

import numpy as np; np.random.seed(0)
import seaborn as sns; sns.set()
uniform_data = np.random.rand(6, 6)/100
ax = sns.heatmap(uniform_data,annot=True, fmt=".2%")
