Use a loop to plot n charts Python

Ok, so the easiest method to create several plots is this: import matplotlib.pyplot as plt x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]] y=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]] for i in range(len(x)): plt.figure() plt.plot(x[i],y[i]) # Show/save figure as desired. # Can show all four figures at once by calling here, outside the loop.
