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.get_label() Function
The Axes.get_label() function in axes module of matplotlib library is used to get the label used for this artist in the legend.
Syntax: Axes.get_label(self)
Parameters: This method does not accepts any parameter.
Returns: This method return the label used for this artist in the legend.
Below examples illustrate the matplotlib.axes.Axes.get_label() function in matplotlib.axes:
Example 1:
# Implementation of matplotlib function import matplotlib.pyplot as plt fig, ax = plt.subplots() x = [ 0 , 1 ] y = [ 1 , 1 ] line, = ax.plot(x, y) ax.legend(( "Line_1" , )) ax.text( 0.2 , 1.02 , "Value Return by get_label()\ : " + str (line.get_label())) fig.suptitle('matplotlib.axes.Axes.get_label() function\ Example\n\n', fontweight = "bold" ) plt.show() |
Output:
Example 2:
# Implementation of matplotlib function import matplotlib.pyplot as plt def make_patch_spines_invisible(ax): ax.set_frame_on( True ) ax.patch.set_visible( False ) for sp in ax.spines.values(): sp.set_visible( False ) fig, host = plt.subplots() fig.subplots_adjust(right = 0.75 ) par1 = host.twinx() par2 = host.twinx() # Offset the right spine of par2. # The ticks and label have already been # placed on the right by twinx above. par2.spines[ "right" ].set_position(( "axes" , 1.2 )) # Having been created by twinx, par2 has # its frame off, so the line of its # detached spine is invisible. First, # activate the frame but make the patch # and spines invisible. make_patch_spines_invisible(par2) # Second, show the right spine. par2.spines[ "right" ].set_visible( True ) p1, = host.plot([ 0 , 1 , 2 ], [ 0 , 1 , 2 ], "b-" , label = "Y-label 1" ) p2, = par1.plot([ 0 , 1 , 2 ], [ 0 , 30 , 20 ], "r-" , label = "Y-label 2" ) p3, = par2.plot([ 0 , 1 , 2 ], [ 500 , 300 , 150 ], "g-" , label = "Y-label 3" ) host.set_xlim( 0.25 , 1.75 ) host.set_ylim( 0.25 , 1.75 ) par1.set_ylim( 0 , 40 ) par2.set_ylim( 10 , 500 ) host.set_xlabel( "X-label" ) host.set_ylabel( "Y-label 1" ) par1.set_ylabel( "Y-label 2" ) par2.set_ylabel( "Y-label 3" ) host.yaxis.label.set_color(p1.get_color()) par1.yaxis.label.set_color(p2.get_color()) par2.yaxis.label.set_color(p3.get_color()) tkw = dict (size = 4 , width = 1.5 ) host.tick_params(axis = 'y' , colors = p1.get_color(), * * tkw) par1.tick_params(axis = 'y' , colors = p2.get_color(), * * tkw) par2.tick_params(axis = 'y' , colors = p3.get_color(), * * tkw) host.tick_params(axis = 'x' , * * tkw) lines = [p1, p2, p3] host.legend(lines, [l.get_label() for l in lines]) fig.suptitle('matplotlib.axes.Axes.get_label()\ function Example\n\n', fontweight = "bold" ) plt.show() |
