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_path_effects() method
The get_path_effects() method in artist module of matplotlib library is used to get the property of set_path_effects.
Syntax: Artist.get_path_effects(self)
Parameters: This method does not accepts any parameter.
Returns: This method return the property of set_path_effects.
Below examples illustrate the matplotlib.artist.Artist.get_path_effects() function in matplotlib:
Example 1:
# Implementation of matplotlib function from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.patheffects as path_effects
fig, ax = plt.subplots()
t = ax.text( 0.02 , 0.5 ,
'GeeksForGeeks' ,
fontsize = 40 ,
weight = 1000 ,
va = 'center' )
t.set_path_effects([path_effects.PathPatchEffect(offset = ( 4 , - 4 ),
hatch = 'xxxx' ,
facecolor = 'gray' ),
path_effects.PathPatchEffect(edgecolor = 'white' ,
linewidth = 1.1 ,
facecolor = 'black' )])
print ( "Value Return by get_path_effects() : \n" )
for i in Artist.get_path_effects(t):
print (i)
fig.suptitle('matplotlib.artist.Artist.get_path_effects()\ function Example', fontweight = "bold" )
plt.show() |
Output:
Value Return by get_path_effects() : <matplotlib.patheffects.PathPatchEffect object at 0x0AAAB890> <matplotlib.patheffects.PathPatchEffect object at 0x0AAABA70>
Example 2:
# Implementation of matplotlib function from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import matplotlib.patheffects as PathEffects
import numpy as np
fig, ax1 = plt.subplots()
ax1.imshow([[ 1 , 2 ], [ 2 , 3 ]])
txt = ax1.annotate( "Fourth" ,
( 1. , 1. ),
( 0. , 0 ),
arrowprops = dict (arrowstyle = "->" ,
connectionstyle = "angle3" ,
lw = 2 ),
size = 20 ,
ha = "center" ,
path_effects = [PathEffects.withStroke(linewidth = 3 ,
foreground = "w" )])
txt.arrow_patch.set_path_effects([ PathEffects.Stroke(linewidth = 5 , foreground = "w" ),
PathEffects.Normal()])
ax1.grid( True , linestyle = "-" )
pe = [PathEffects.withStroke(linewidth = 3 ,
foreground = "w" )]
for l in ax1.get_xgridlines() + ax1.get_ygridlines():
l.set_path_effects(pe)
print ( "Value Return by get_path_effects() : \n" )
for l in ax1.get_xgridlines() + ax1.get_ygridlines():
for i in Artist.get_path_effects(l):
print (i)
fig.suptitle('matplotlib.artist.Artist.get_path_effects()\ function Example', fontweight = "bold" )
plt.show() |
Output:
Value Return by get_path_effects() : <matplotlib.patheffects.withStroke object at 0x0A66DBD0> < <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0> <matplotlib.patheffects.withStroke object at 0x0A66DBD0>
