Matplotlib.pyplot.get_figlabels() in Python

Last Updated : 10 May, 2020

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. There are various plots which can be used in Pyplot are Line Plot, Contour, Histogram, Scatter, 3D Plot, etc.

matplotlib.pyplot.get_figlabels() method

The get_figlabels() method in pyplot module of matplotlib library is used to get the list of existing figure labels.

Syntax: matplotlib.pyplot.get_figlabels()

Parameters: This method does not accept any parameters.

Returns: This method returns the list of existing figure labels.

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

Example 1:

import matplotlib.pyplot as plt 
import numpy as np 
     
  
t = np.arange(0.01, 5.0, 0.01) 
s = np.exp(-t) 
     
plt.plot(t, s) 
plt.ylim(1, 0) 
plt.ylabel('Display Y-axis Label', fontweight ='bold') 
plt.grid(True) 
  
w = plt.get_figlabels() 
  
plt.text(1.5, 0.58, 
         "List of existing figure labels : \n"
         + str(w), 
         fontsize = 12) 
     
plt.title('matplotlib.pyplot.get_figlabels() function\ 
 Example', fontweight ="bold")  
  
plt.show() 

Output:

Example 2:

import matplotlib.pyplot as plt 
import matplotlib as mpl 
import matplotlib.patches as patches 
import numpy as np 
   
      
mpl.rcParams['figure.dpi'] = 80
mpl.rcParams['savefig.dpi'] = 80 
  
def redraw(event): 
      
    if  np.size(plt.get_figlabels()): 
        ax.clear() 
        drawRectangles(ax) 
        fig.canvas.draw() 
    else: 
        pass
   
   
def drawRectangles(ax): 
      
    td2dis = ax.transData 
    coords = td2dis.transform([0.2, 0.5]) 
    tr = mpl.transforms.Affine2D().rotate_deg_around(coords[0], 
                                                     coords[1], 10) 
    t = td2dis + tr 
    rec0 = patches.Rectangle((0.5, 0.5), 
                             0.25, 0.2,  
                             color = 'green',  
                             alpha = 0.4) 
    ax.add_patch(rec0) 
    rect1 = patches.Rectangle((0.5, 0.5), 
                              0.25, 0.2, 
                              color = 'green', 
                              alpha = 0.7, 
                              transform = t) 
    ax.add_patch(rect1); 
    plt.title('matplotlib.pyplot.get_figlabels() function Example', fontweight ="bold") 
    plt.grid() 
   
   
figSize = (8, 6) 
fig = plt.figure("Patch rotate", figsize = figSize) 
   
ax = fig.add_subplot(111) 
ax.set_xlim(0, 1);ax.set_ylim(0, 1); 
  
fig.canvas.mpl_connect('resize_event', redraw) 
drawRectangles(ax)  
  
plt.show()
