Matplotlib.axes.Axes.can_zoom() in Python

0 0 1 minute read

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.can_zoom() Function

The Axes.can_zoom() Function in axes module of matplotlib library is used to check whether the axes supports any zoom box button functionality or not.

Syntax: Axes.can_zoom(self)

Parameters: This method does not accept any parameters.

Return value: This method returns boolean value True if supports any zoom box button functionality.

Below examples illustrate the matplotlib.axes.Axes.can_zoom() function in matplotlib.axes:
Example 1:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import numpy as np 
  
     
fig, ax = plt.subplots() 
ax.plot([1, 2, 3]) 
  
w = ax.can_zoom() 
  
ax.text(0.45, 2.75, "Value return by function:", 
        fontweight ="bold") 
ax.text(0.9, 2.6, w, fontweight ="bold") 
  
fig.suptitle('matplotlib.axes.Axes.can_zoom() function \ 
Example\n\n', fontweight ="bold") 
  
plt.show() 

Output:

Example 2:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib.widgets import Slider, Button, RadioButtons 
     
fig, ax1 = plt.subplots() 
plt.subplots_adjust(bottom = 0.25) 
t = np.arange(0.0, 1.0, 0.001) 
a0 = 5
f0 = 3
delta_f = 5.0
s = a0 * np.sin(2 * np.pi * f0 * t) 
     
ax1.plot(t, s, lw = 2, color = 'green') 
ax1.set_ymargin(0.5) 
  
w = ax1.can_zoom() 
  
ax1.text(0.25, 7.5, "Value return by function:", 
         fontweight ="bold") 
ax1.text(0.47, 5.6, w, fontweight ="bold") 
  
fig.suptitle('matplotlib.axes.Axes.can_zoom() function \ 
Example\n\n', fontweight ="bold") 
  
plt.show()
