Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Artist class contains Abstract base class for objects that render into a FigureCanvas. All visible elements in a figure are subclasses of Artist.
Matplotlib.artist.Artist.get_agg_filter() Method
The get_agg_filter() method in artist module of matplotlib library is used to get the filter function to be used for agg filter.
Syntax: Artist.get_agg_filter(self)
Parameters: This method does not accepts any parameter.
Returns: This method return filter function to be used for agg filter.
Below examples illustrate the matplotlib.artist.Artist.get_agg_filter() function in matplotlib:
Example 1:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.artist import Artist
xx = np.random.rand( 16 , 30 )
fig, axs = plt.subplots()
m = axs.pcolor(xx)
m.set_zorder( - 20 )
val = Artist.get_agg_filter(axs)
axs.set_title( "Value Return by get_agg_filter(): "
+ str (val))
fig.suptitle('matplotlib.artist.Artist.get_agg_filter() \
function Example', fontweight = "bold" )
plt.show()
|
Output:
Example 2:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.artist import Artist
np.random.seed( 10 * * 7 )
geeks = np.random.randn( 40 )
fig, axs = plt.subplots()
axs.acorr(geeks, usevlines = True , normed = True ,
maxlags = 30 , lw = 2 )
axs.grid( True )
val = Artist.get_agg_filter(axs)
axs.set_title( "Value Return by get_agg_filter(): "
+ str (val))
fig.suptitle('matplotlib.artist.Artist.get_agg_filter() \
function Example', fontweight = "bold" )
plt.show()
