Plot matrix of weighted cells in grid with Matplotlib
I have a square matrix built from an array of random integers, defined below:
import numpy as np
dim_low, dim_high = 0, 20 #array of random integers' dimensions
matrix = np.random.random_integers(low = dim_low,high = dim_high, size=(dim_high,dim_high))
print(matrix) #the matrix of defined with repetitions of the array.
Resulted matrix in the picture:

What could I do to plot the matrix generated in a grid with Matplotlib, in a way that the values of each cell (the weights) are printed in the center of each cell, and there's a scale from 0 to 20 in x an y axis, as in the picture below (notice that 'x' and 'o' are text in the example, what I need is the weights, in integer form, not text form):

If you are capable of producing the image shown, what's the difference to putting your matrix elements in the text instead of some letters"o"? Which exact problem are you trying to solve?

Try using https://seaborn.pydata.org/generated/seaborn.heatmap.html. I won't take you through the different options because they're really well documented.
Goodluck!
BTW, you'll want to use a panda pivot table for comfortable compatibility.
