Python Matplotlib.axes.Axes.add_collection()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.add_collection()函數

matplotlib庫的axiss模塊中的Axes.add_collection()函數用於將Collection添加到軸的collection中;返回集合。

用法: Axes.add_collection(self, collection, autolim=True)


參數:此方法接受以下參數。

  • collection:該參數是collection()函數產生的集合。

返回值:此方法返回集合。

以下示例說明了matplotlib.axes.Axes.add_collection()matplotlib.axes中的函數:

範例1:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
from matplotlib.collections import EventCollection 
import numpy as np 
  
np.random.seed(19680801) 
xvalue = np.random.random([2, 10]) 
xvalue1 = xvalue[0,:] 
xvalue2 = xvalue[1,:] 
xvalue1.sort() 
xvalue2.sort() 
  
yvalue1 = xvalue1 ** 4
yvalue2 = 1 - xvalue2 ** 6
  
fig = plt.figure() 
ax = fig.add_subplot(1, 1, 1) 
ax.plot(xvalue1, yvalue1, color ='tab:blue') 
ax.plot(xvalue2, yvalue2, color ='tab:green') 
  
xresult1 = EventCollection(xvalue1, color ='tab:blue') 
xresult2 = EventCollection(xvalue2, color ='tab:green') 
yresult1 = EventCollection(yvalue1, color ='tab:blue', 
                           orientation ='vertical') 
yresult2 = EventCollection(yvalue2, color ='tab:green', 
                           orientation ='vertical') 
ax.add_collection(xresult1) 
ax.add_collection(xresult2) 
ax.add_collection(yresult1) 
ax.add_collection(yresult2) 
  
ax.set_xlim([0, 1]) 
ax.set_ylim([0, 1]) 
  
fig.suptitle('matplotlib.axes.Axes.add_collection() \ 
function Example\n\n', fontweight ="bold") 
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
from matplotlib.collections import LineCollection 
from matplotlib import colors as mcolors 
import numpy as np 
  
N = 50
x = np.arange(N) 
  
ys = [i/(x + 1) for i in x] 
  
fig, ax = plt.subplots() 
ax.set_xlim(0, 20) 
ax.set_ylim(0, 20) 
  
line_segments = LineCollection([np.column_stack([x, y]) for y in ys], 
                               linewidths =(0.5, 1, 1.5, 2), 
                               linestyles ='dashed',  
                               color ="# eeffdd") 
line_segments.set_array(x**2) 
ax.add_collection(line_segments) 
  
fig.suptitle('matplotlib.axes.Axes.add_collection()\ 
 function Example\n\n', fontweight ="bold") 
plt.show()

輸出:
