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() |
Output:
