Matplotlib是Python中的一个库，它是数字的-NumPy库的数学扩展。 Artist类包含用于呈现到FigureCanvas中的对象的Abstract基类。图中所有可见元素都是Artist的子类。
matplotlib.artist.Artist.set_path_effects()方法
matplotlib库的美工模块中的set_path_effects()方法用于设置路径效果。
用法：Artist.set_path_effects(self, path_effects)
参数：此方法接受以下参数。
- path_effects:此参数是AbstractPathEffect。
返回值：此方法不返回任何值。
以下示例说明了matplotlib中的matplotlib.artist.Artist.set_path_effects()函数：
范例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')
Artist.set_path_effects(t, [path_effects.PathPatchEffect(offset =(4, -4),
hatch ='xxxx',
facecolor ='lightgreen'),
path_effects.PathPatchEffect(edgecolor ='white',
linewidth = 1.1,
facecolor ='green')])
fig.suptitle('matplotlib.artist.Artist.set_path_effects()\
function Example', fontweight ="bold")
plt.show()输出：
范例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 Qaud",
(1., 1.),
(0., 0),
arrowprops = dict(arrowstyle ="->",
connectionstyle ="angle3",
lw = 2),
size = 20, ha ="center",
path_effects =[PathEffects.withStroke(linewidth = 3,
foreground ="w")])
Artist.set_path_effects(txt.arrow_patch, [
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():
Artist.set_path_effects(l, pe)
fig.suptitle('matplotlib.artist.Artist.set_path_effects()\
function Example', fontweight ="bold")
plt.show()输出：
