The update() method in artist module of matplotlib library is used to update this artist’s properties from the dictionary props.

Below examples illustrate the matplotlib.artist.Artist.update() function in matplotlib:
Example 1:
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
np.random.seed( 10 * * 7 )
geeks = np.random.randn( 100 )
fig, ax = plt.subplots()
ax.acorr(geeks, usevlines = True ,
normed = True ,
maxlags = 80 , lw = 3 )
ax.grid( True )
prop = { 'xticks' : np.array([ - 10. , - 5. ,
0. , 5. , 10. ]),
'yticks' : np.array([ - 0.2 , 0.2 ,
0.6 , 1. , 1.4 ]),
'ylabel' : None , 'xlabel' : None }
Artist.update(ax, prop)
fig.suptitle('matplotlib.artist.Artist.update()\
function Example', fontweight = "bold" )
plt.show()
|
Output:
Example 2:
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
xx = np.random.rand( 16 , 30 )
fig, ax = plt.subplots()
m = ax.pcolor(xx)
m.set_zorder( - 20 )
prop = { 'autoscalex_on' : False }
Artist.update(ax, prop)
fig.suptitle('matplotlib.artist.Artist.update() \
function Example', fontweight = "bold" )
plt.show()
