Matplotlib.axes.axes.get_yminorticklabels()

Matplotlib是Python中的一个库，它是NumPy库的数值-数学扩展。Axes包含了大多数图形元素:Axis、Tick、Line2D、Text、Polygon等，并设置坐标系。Axes的实例通过callbacks属性支持回调。

matplotlib.axes.Axes.get_yminorticklabels() Function:

matplotlib库的Axes模块中的Axes.get_yminorticklabels()函数用于返回次要的y刻度标签。

语法:Axes.get_yminorticklabels(self)

参数:该方法不接受任何参数。

返回值:该方法返回List of Text实例。

下面的例子演示了matplotlib.axes.axes.get_yminorticklabels()函数在matplotlib.axes中的作用:

示例1

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
  
  
fig, ax = plt.subplots()
ax.plot(range(12, 24), range(12))
ax.set_yticks((2, 5, 7, 10))
ax.set_yticklabels(("Label-1", "Label-2",
                    "Label-3", "Label-4"))
   
w = ax.get_yminorticklabels()
ax.text(15, 8, "yminorticklabels values : " + str(list(w)), 
        fontweight ="bold")
  
fig.suptitle('matplotlib.axes.Axes.get_yminorticklabels()\
 function Example\n\n', fontweight ="bold")
plt.show()

输出:

示例2

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.mlab as mlab
import matplotlib.gridspec as gridspec
  
  
fs = 1000
t = np.linspace(0, 0.3, 301)
A = np.array([2, 8]).reshape(-1, 1)
f = np.array([150, 140]).reshape(-1, 1)
xn = (A * np.sin(2 * np.pi * f * t)).sum(axis = 0)
xn += 5 * np.random.randn(*t.shape)
   
fig, ax = plt.subplots()
   
yticks = [-40, -15, 10]
   
ax.psd(xn, NFFT = 301, Fs = fs,
       window = mlab.window_none, 
       pad_to = 1024,
       scale_by_freq = True)
  
ax.set_yticks(yticks)
ax.set_yticklabels(("Low-1", "High", "Low-2"))
ax.grid(True)
   
w = ax.get_yminorticklabels()
ax.text(150, 6, "yminorticklabels values : " + str(list(w)),
        fontweight ="bold")
  
fig.suptitle('matplotlib.axes.Axes.get_yminorticklabels() \
function Example\n\n', fontweight ="bold")
plt.show()

输出:
