In Matlab I can visualize a matrix data quite easily with
data = rand(10,10); % Createas a 10 x 10 random matrix
imagesc(data);
colorbar;
Now I want to do the same thing in python. I already know how to plot a 2d matrix (numpy array):
from matplotlib.pyplot import imshow
import numpy as np
data = np.random.random((10,10))
imshow(np.asarray(img))
but I don't know how to add a colorbar to it. Any ideas?
import numpy as np
import matplotlib.pyplot as plt
plt.imshow(np.random.random((50,50)))
plt.colorbar()
plt.show()
Another possibility is to use plt.matshow()
import numpy as np
import matplotlib.pyplot as plt
plt.matshow(np.random.random((50,50)));
plt.colorbar()
plt.show()
