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:
# Implementation of matplotlib function 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) # use of get_agg_filter() method 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:
# Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt from matplotlib.artist import Artist np.random.seed(10**7) neveropen = np.random.randn(40) fig, axs = plt.subplots() axs.acorr(neveropen, usevlines=True, normed=True, maxlags=30, lw=2) axs.grid(True) # use of get_agg_filter() method 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:
