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

matplotlib库的axis模块中的axis.set_label_text()函数用于设置轴标签的文本值。

以下示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.set_label_text()函数:

示例 1:

Python3
# Implementation of matplotlib function 
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
   
fig, ax2 = plt.subplots(sharex = True)
fig.subplots_adjust(left=0.2, wspace=0.6)
box = dict(facecolor='green', pad=5, alpha=0.2)
   
ax2.plot(20*np.random.rand(10))
ax2.xaxis.set_label_text('X - Label', bbox=box)
ax2.set_xlim(0, 10)
   
fig.suptitle("Matplotlib.axis.Axis.set_label_text()\
Function Example", fontsize = 12, fontweight ='bold') 
  
plt.show()


Python3
# Implementation of matplotlib function 
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
    
fig, (ax1, ax2) = plt.subplots(2, 1, sharex = True)
fig.subplots_adjust(left=0.2, wspace=0.6)
box = dict(facecolor='green', pad=5, alpha=0.2)
    
np.random.seed(19680801)
ax1.plot(2*np.random.rand(10))
ax1.set_title('Label is not aligned')
ax1.yaxis.set_label_text('Default', bbox=box)
ax1.set_ylim(0, 20)
    
ax2.set_title('\nLabel is aligned')
ax2.plot(20*np.random.rand(10))
ax2.yaxis.set_label_text('Adjusted', bbox=box)
ax2.yaxis.set_label_position('right')
ax2.set_ylim(0, 20)
    
fig.suptitle("Matplotlib.axis.Axis.set_label_text()\
Function Example", fontsize = 12, fontweight ='bold') 
  
plt.show()


输出:
