figure of imshow() is too small

Question

I\'m trying to visualize a numpy array using imshow() since it\'s similar to imagesc() in Matlab.

imshow(random.rand(8, 90), interpolation=\'nearest\')
         


        

Answer 1

Update 2020

as requested by @baxxx, here is an update because random.rand is deprecated meanwhile.

This works with matplotlip 3.2.1:

from matplotlib import pyplot as plt
import random
import numpy as np

random = np.random.random ([8,90])

plt.figure(figsize = (20,2))
plt.imshow(random, interpolation='nearest')

This plots:

To change the random number, you can experiment with np.random.normal(0,1,(8,90)) (here mean = 0, standard deviation = 1).
