Python Forum

I'm starting to learn matplotlib, following the pyplot tutorial, but something weird—I think—is happening in the very first part.

When I do this,

import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()

plt.plot([1, 2, 3, 4]) creates the figure, but plt.ylabel('some numbers') creates another figure with the label but with no plot. Nothing about this is mentioned in the tutorial, and I have been reading about the plt functions to see if this is supposed to happen and/or how to fix it, but can't find anything. What can I do about this?

I just installed matplotlib 3.1.3 and I'm running Python 3.7.6 on Spyder 4.0.1

I see that, in this version of Spyder, I don't need to use plt.show(), because all figures are shown in the 'Plots' pane.

Thanks in advance.
