display matrix values and colormap

Question

I need to display values of my matrix using matshow. However, with the code I have now I just get two matrices - one with values and other colored. How do I impose them? Thanks

Answer 1

In Jupyter notebooks this is also possible with DataFrames and Seaborn:

import numpy as np
import seaborn as sns
import pandas as pd

min_val, max_val = 0, 15
intersection_matrix = np.random.randint(0, 10, size=(max_val, max_val))
cm = sns.light_palette("blue", as_cmap=True)
x=pd.DataFrame(intersection_matrix)
x=x.style.background_gradient(cmap=cm)
display(x)
