Python Matplotlib.axes.Axes.set_gid()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_gid()函數

matplotlib庫的axes模塊中的Axes.set_gid()函數用於設置藝術家的(組)ID。

用法: Axes.set_gid(self, gid)


參數:此方法僅接受一個參數。

  • gid:此參數是作為gid給出的字符串。

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_gid()函數:

範例1:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
   
  
y, x = np.mgrid[:5, 1:6] 
poly_coords = [ 
    (0.25, 2.75), (3.25, 2.75), 
    (2.25, 0.75), (0.25, 0.75) 
] 
  
fig, ax = plt.subplots() 
   
cells = ax.plot(x, y, x + y, color ='green') 
ax.add_patch( 
    plt.Polygon(poly_coords,  
                color ='forestgreen',  
                alpha = 0.5) 
    ) 
ax.margins(x = 0.1, y = 0.05) 
ax.set_aspect('equal') 
  
for i, t in enumerate(ax.patches):
    t.set_gid('patch_% d' % i) 
   
fig.suptitle('matplotlib.axes.Axes.set_gid() \ 
function Example\n\n', fontweight ="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
  
   
fig, ax = plt.subplots() 
  
circle = plt.Circle((0, 0), 5, fc ='blue') 
rect = plt.Rectangle((-5, 10), 10, 5, fc ='green') 
  
ax.add_patch(circle) 
ax.add_patch(rect) 
  
circle_tip = ax.annotate('This is a blue circle.', 
            xy =(0, 0), 
            xytext =(30, -30), 
            textcoords ='offset points', 
            color ='w', 
            ha ='left', 
            bbox = dict(boxstyle ='round, pad =.5',  
                        fc =(.1, .1, .1, .92), 
                        ec =(1., 1., 1.),  
                        lw = 1, 
                        zorder = 1), 
            ) 
  
rect_tip = ax.annotate('This is a green rectangle.', 
            xy =(-5, 10), 
            xytext =(30, 40), 
            textcoords ='offset points', 
            color ='w', 
            ha ='left', 
            bbox = dict(boxstyle ='round, pad =.5', 
                        fc =(.1, .1, .1, .92),  
                        ec =(1., 1., 1.),  
                        lw = 1, 
                        zorder = 1), 
            ) 
  
for i, t in enumerate(ax.patches):
    t.set_gid('patch_% d'% i) 
  
for i, t in enumerate(ax.texts):
    t.set_gid('tooltip_% d'% i) 
  
ax.set_xlim(-30, 30) 
ax.set_ylim(-30, 30) 
ax.set_aspect('equal') 
   
fig.suptitle('matplotlib.axes.Axes.set_gid() function \ 
Example\n\n', fontweight ="bold") 
  
plt.show()
