Python中的 Matplotlib.axis.Axis.get_majorticklocs()函数

Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。

matplotlib.axis.Axis.get_majorticklocs()函数

matplotlib 库的轴模块中的Axis.get_majorticklocs()函数用于获取数据坐标中主要刻度位置的数组。

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_majorticklocs()函数:

示例 1:

Python3
# Implementation of matplotlib function 
from matplotlib.axis import Axis  
from matplotlib.artist import Artist 
from mpl_toolkits.mplot3d import axes3d   
import matplotlib.pyplot as plt   
          
fig, ax = plt.subplots()   
          
def tellme(s):   
    ax.set_title(s, fontsize = 16)   
    fig.canvas.draw()  
    renderer = fig.canvas.renderer  
    Artist.draw(ax, renderer)  
        
tellme("Matplotlib.axis.Axis.get_majorticklocs()\n\
Function Example")
ax.grid()  
  
print("Value of get_majorticklocs() :")
for i in ax.xaxis.get_majorticklocs():
    print(i)
      
plt.show()


Python3
# Implementation of matplotlib function 
from matplotlib.axis import Axis  
from matplotlib.artist import Artist 
from mpl_toolkits.mplot3d import axes3d   
import matplotlib.pyplot as plt   
         
      
fig = plt.figure()   
ax = fig.add_subplot(111, projection ='3d')   
         
X, Y, Z = axes3d.get_test_data(0.1)   
ax.plot_wireframe(X, Y, Z, rstride = 5,    
                  cstride = 5)   
         
  
ax.view_init(30, 50)  
fig.canvas.draw()  
renderer = fig.canvas.renderer  
Artist.draw(ax, renderer)   
  
fig.suptitle('Matplotlib.axis.Axis.get_majorticklocs()\n\
Function Example')  
ax.grid()
  
print("Value of get_majorticklocs() :")
for i in ax.xaxis.get_majorticklocs():
    print(i)
      
plt.show()


输出:

Value of get_majorticklocs() :
0.0
0.2
0.4
0.6000000000000001
0.8
1.0

print("Value of get_majorticklocs() :")
for i in ax.xaxis.get_majorticklocs():
    print(i)
      
plt.show()

输出:

Value of get_majorticklocs() :
-40.0
-30.0
-20.0
-10.0
0.0
10.0
20.0
30.0
40.0
