Python Matplotlib.axes.Axes.set_path_effects()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素:Axis,Tick,Line2D,Text,Polygon等,並設置坐標係。 Axes實例通過callbacks屬性支持回調。

matplotlib.axes.Axes.set_path_effects()函數

matplotlib庫的axiss模塊中的Axes.set_path_effects()函數用於設置路徑效果。

用法: Axes.set_path_effects(self, path_effects)


參數:此方法僅接受一個參數。

  • 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.axes中的matplotlib.axes.Axes.set_path_effects()函數:

範例1:

# Implementation of matplotlib function 
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')]) 
   
fig.suptitle('matplotlib.axes.Axes.set_path_effects() function\ 
Example\n', fontweight ="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
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) 
   
fig.suptitle('matplotlib.axes.Axes.set_path_effects() \ 
function Example\n', fontweight ="bold") 
  
plt.show()

輸出:
