You either need to close the figure in the loop, or reuse the same
figure and cla it, eg
for i in range(1000):
fig = plt.figure()
# plot something
plt.close(fig)
or explicitly reuse the same fig by giving a figure number and clearing it:
for i in range(1000):
fig = plt.figure(1)
# plot something
fig.cla()
