Matplotlib.axes.axes.get_axisbelow()

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。

函数:matplotlib.axes.axes.get_axisbelow

matplotlib库的Axes模块中的Axes.get_axisbelow()函数用于获取轴刻度和网格线是在大多数艺术家的上方还是下方。

语法:Axes.get_axisbelow(self)

参数:该方法不接受任何参数。

返回:该方法返回axisbelow。这是我们获得轴刻度和网格线是高于还是低于大多数艺术家的值。

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

示例1

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
  
# Random test data
np.random.seed(19680801)
all_data = [np.random.normal(0, std, size = 100) for std in range(1, 6)]
labels = ['x1', 'x2', 'x3', 'x4', 'x5']
  
fig, ax = plt.subplots()
  
bplot = ax.boxplot(all_data,
                     vert = True,  
                     patch_artist = True,  
                     labels = labels) 
colors = ['lightpink', 'lightblue', 'lightgreen', 
          "lightgrey", "yellow"]
  
for patch, color in zip(bplot['boxes'], colors):
    patch.set_facecolor(color)
  
ax.yaxis.grid(True, color ="green", lw = 2)
ax.set_axisbelow(True)
ax.set_xlabel('Samples')
ax.set_ylabel('Observed values')
x = ax.get_axisbelow()
ax.text(2, 15.7, "Result of get_axisbelow : " +str(x),
        style ='italic', fontsize = 12, color ="green")
  
ax.set_title('matplotlib.axes.Axes.get_axisbelow() \
Example\n\n', fontsize = 12, fontweight ='bold')
plt.show()

输出:

Matplotlib.axes.axes.get_axisbelow()
