I have written code that opens 16 figures at once. Currently they all open as separate graphs. I\'d like them to open all on the same page. Not the same graph. I want 16
To answer your main question, you want to use the subplot command. I think changing plt.figure(i) to plt.subplot(4,4,i+1) should work.
plt.figure(i)
plt.subplot(4,4,i+1)
