Matplotlib.pyplot.disconnect() in Python

0 0 1 minute read

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.

matplotlib.pyplot.disconnect() Function

The disconnect() function in pyplot module of matplotlib library is used to disconnect the callback with id cid.

Syntax: matplotlib.pyplot.disconnect(cid)

Parameters: This method accept the following parameters that are described below:

cid: This parameter is used to disconnect the callback.

Below examples illustrate the matplotlib.pyplot.disconnect() function in matplotlib.pyplot:

Example #1:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
  
fig, ax = plt.subplots() 
ax.plot(np.random.rand(10)) 
  
def onclick(event): 
    print('% s click: button =% d, x =% d, y =% d,\ 
    xdata =% f, ydata =% f' %
          ('double' if event.dblclick else 'single', 
           event.button, 
           event.x, 
           event.y,  
           event.xdata,  
           event.ydata)) 
  
cid = fig.canvas.mpl_connect('button_press_event', 
                             onclick) 
fig.canvas.mpl_disconnect(cid) 
  
plt.suptitle('matplotlib.pyplot.disconnect()\ 
function Example', fontweight ="bold") 
  
plt.show() 

Output:

Example #2:

# Implementation of matplotlib function 
from matplotlib.backend_bases import MouseButton 
import matplotlib.pyplot as plt 
import numpy as np 
  
t = np.arange(0.0, 1.0, 0.01) 
s = np.sin(2 * np.pi * t) 
fig, ax = plt.subplots() 
ax.plot(t, s) 
  
  
def gfg1(event): 
      
    # get the x and y pixel coords 
    x, y = event.x, event.y 
    if event.inaxes: 
          
        # the axes instance 
        ax = event.inaxes 
        print('Coordinates : % f  and\ 
        % f' % (event.xdata, event.ydata)) 
  
  
def gfg2(event): 
      
    if event.button is MouseButton.LEFT: 
        print('Successfully disconnected') 
        plt.disconnect(binding_id) 
  
  
binding_id = plt.connect('motion_notify_event', 
                         gfg1) 
  
plt.connect('button_press_event', gfg2) 
  
plt.suptitle('matplotlib.pyplot.disconnect()\ 
function Example', fontweight ="bold") 
plt.show()
