Bug report
Bug summary
When creating multiple plots (e.g. in a loop), the allocated memory for the process increases in each iteration even though the figure is cleared each time.
Code for reproduction
import gc
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
for i in range(5000):
fig.clf()
plt.cla()
ax.plot([0,1,2,3,4,5], [0,1,2,3,4,5])
plt.close('all')
plt.close(fig)
gc.collect()Expected outcome
The allocated memory should not increase in each iteration.
