Matplotlib.axis.axis.get_data_interval()

matplotlib库Axis模块中的Axis.get_data_interval()函数用于获取该轴数据限制的Interval实例。

语法:Axis.get_data_interval(self)

参数:该方法不接受任何参数。

返回值:该方法返回此轴数据限制的Interval实例。

下面的例子说明了matplotlib.axis.axis.get_data_interval()函数在matplotlib.axis中的作用:

示例1

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np 
   
fig = plt.figure()
   
x = np.linspace(0,4*np.pi,100)
y = 2*np.sin(x)
   
ax = fig.add_subplot()
ax.plot(x,y)
  
print("Value return by get_data_interval() :")
w = ax.xaxis.get_data_interval()
print(w)
   
ax.grid() 
   
fig.suptitle("""matplotlib.axis.Axis.get_data_interval()
function Example\n""", fontweight ="bold")  
     
plt.show()

输出:

Value return by get_data_interval() :
[ 0.         12.56637061]

示例2

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np 
   
np.random.seed(10**7)  
geeks = np.random.randn(40)  
        
fig, ax = plt.subplots()  
ax.acorr(geeks, usevlines = True,  
         normed = True,  
         maxlags = 20, lw = 3)  
       
ax.grid(True)
  
print("Value return by get_data_interval() :")
w = ax.xaxis.get_data_interval()
print(w)
   
fig.suptitle("""matplotlib.axis.Axis.get_data_interval()
function Example\n""", fontweight ="bold")  
     
plt.show()

输出:

Value return by get_data_interval() :
[-20.  20.]
