Python Matplotlib.figure.Figure.add_artist()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。 Figure模塊提供了頂層Artist,即Figure,其中包含所有繪圖元素。此模塊用於控製所有圖元的子圖和頂層容器的默認間距。

matplotlib.figure.Figure.add_artist()函數

matplotlib庫的add_artist()方法人物模型模塊用於向該人物添加任何Artist。

用法: add_artist(self, artist, clip=False)


參數:這接受以下描述的以下參數:

  • artist:此參數是要添加到圖形中的美術師。
  • clip:此參數用於確定是否應使用圖形補丁剪切添加的藝術家。

返回值:此方法返回添加的Artist

以下示例說明了matplotlib.figure中的matplotlib.figure.Figure.add_artist()函數:

範例1:

# Implementation of matplotlib function 
import numpy as np 
np.random.seed(19680801) 
import matplotlib.pyplot as plt 
   
      
fig, ax = plt.subplots() 
  
volume = np.random.rayleigh(27, size = 40) 
amount = np.random.poisson(10, size = 40) 
ranking = np.random.normal(size = 40) 
price = np.random.uniform(1, 10, size = 40) 
   
scatter = ax.scatter(volume * 2, 
                     amount * 3,  
                     c = ranking * 3, 
                     s = 0.3*(price * 3)**2, 
                     vmin =-4, 
                     vmax = 4, 
                     cmap ="Spectral") 
  
legend1 = ax.legend(*scatter.legend_elements(num = 5), 
                    loc ="upper left", title ="Ranking") 
  
fig.add_artist(legend1) 
   
kw = dict(prop ="sizes", 
          num = 5, 
          color = scatter.cmap(0.7), 
          fmt =" {x:.2f}", 
          func = lambda s:np.sqrt(s/.3)/3) 
  
legend2 = ax.legend(*scatter.legend_elements(**kw), 
                    loc ="lower right", title ="Size") 
   
fig.suptitle('matplotlib.figure.Figure.add_artist() \ 
function Example\n\n', fontweight ="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.patches import Ellipse 
   
NUM = 200
   
ells = [Ellipse(xy = np.random.rand(2) * 10, 
                width = np.random.rand(), height = np.random.rand(), 
                angle = np.random.rand() * 360) 
        for i in range(NUM)] 
   
fig, ax = plt.subplots(subplot_kw ={'aspect':'equal'}) 
for e in ells:
    fig.add_artist(e) 
    e.set_clip_box(ax.bbox) 
    e.set_alpha(np.random.rand()) 
    e.set_facecolor(np.random.rand(4)) 
   
ax.set_xlim(3, 7) 
ax.set_ylim(3, 7) 
   
fig.suptitle('matplotlib.figure.Figure.add_artist()\ 
 function Example\n\n', fontweight ="bold") 
  
plt.show()

輸出:
