Matplotlib是Python中的一個庫，它是數字的-NumPy庫的數學擴展。 Artist類包含用於呈現到FigureCanvas中的對象的Abstract基類。圖中所有可見元素都是Artist的子類。
matplotlib.artist.Artist.set_path_effects()方法
matplotlib庫的美工模塊中的set_path_effects()方法用於設置路徑效果。
用法：Artist.set_path_effects(self, path_effects)
參數：此方法接受以下參數。
- path_effects:此參數是AbstractPathEffect。
返回值：此方法不返回任何值。
以下示例說明了matplotlib中的matplotlib.artist.Artist.set_path_effects()函數：
範例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()輸出：
範例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()輸出：
