Hello
I'm not a professional, but I'm not a beginner either
I have been working with matplotlib since 2013 (see for example issue # 1957)
my system:
Win10(64), IDE PyCharm, python 3.8.2 (64), numpy 1.19.2, matplotlib 3.2.2 and 3.3.0
I mainly use:
matplotlib.pyplot as plt
fig, ax=plt.subplot(...)
ax.plot(...)
ax.fill_between(...)
plt.show()
my plot data:
4 rows each 525600 points (365day * 24hour * 60 min)
the problem:
with mpl 3.2.2 the creation of the plot example 1 takes 4 seconds
but
with mpl 3.3.0 the creation of the plot example 1 takes 31 seconds
and
with mpl 3.2.2 the creation of the plot example 2 takes 13 seconds
but
with mpl 3.3.0 the creation of the plot example 2 takes 82 seconds
example 1
example 2
the question:
Why is this enormous extension of the creation time?
What has changed from mpl 3.2.2 to 3.3.0?
Thank you
