How to suppress matplotlib warning?

Question

I am getting an warning from matplotlib every time I import pandas:

/usr/local/lib/python2.7/site-packages/matplotlib/__init__.py:8         


        

Answer 1

You can suppress the warning UserWarning: axes.color_cycle is deprecated and replaced with axes.prop_cycle; please use the latter. by using prop_cycle at the appropriate place.

For example, in the place you had used color_cycle:

matplotlib.rcParams['axes.color_cycle'] = ['r', 'k', 'c']

Replace it with the following:

matplotlib.rcParams['axes.prop_cycle'] = mpl.cycler(color=["r", "k", "c"]) 

For a greater glimpse, here is an example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

mpl.rcParams['axes.prop_cycle'] = mpl.cycler(color=["r", "k", "c"]) 

x = np.linspace(0, 20, 100)

fig, axes = plt.subplots(nrows=2)

for i in range(10):
    axes[0].plot(x, i * (x - 10)**2)

for i in range(10):
    axes[1].plot(x, i * np.cos(x))

plt.show()
