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.broken_barh() Function

The Axes.broken_barh() function in axes module of matplotlib library is used to plot a horizontal sequence of rectangles.

Syntax:

Axes.broken_barh(self, xranges, yrange, *, data=None, **kwargs)

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

  • y: This parameter is the sequence of y coordinates of the bar.
  • xranges: This parameter is the sequence of tuples (xmin, xwidth).It is the x-positions and extends of the rectangles.
  • yrange: This parameter is the sequence of tuples (ymin, yheight).It is the y-positions and extends for all the rectangles.

Returns: This returns the following:

  • BrokenBarHCollection:This returns the container with all the broken_barh.

Below examples illustrate the matplotlib.axes.Axes.broken_barh() function in matplotlib.axes:

Example #1:




# Implementation of matplotlib function
import matplotlib.pyplot as plt
  
fig, ax = plt.subplots()
ax.broken_barh([(110, 30), (150, 10)],
               (10, 9), 
               facecolors ='tab:green')
  
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.grid(True)
  
ax.set_title('matplotlib.axes.Axes.\
broken_barh Example')
plt.show()

Output:

Example #2:




# Implementation of matplotlib function
import matplotlib.pyplot as plt
  
fig, ax = plt.subplots()
ax.broken_barh([(110, 30), (150, 10)], 
               (10, 9), 
               facecolors ='tab:green')
  
ax.broken_barh([(100, 20),
                (130, 10)], 
               (20, 9), 
               facecolors =('tab:green'))
  
ax.set_ylim(5, 35)
ax.set_xlim(50, 200)
ax.set_xlabel('Learning Rate')
ax.set_yticks([15, 25])
ax.set_yticklabels(['Geeks1', 'Geeks2'])
ax.grid(True)
  
ax.annotate('Broken', (125, 25),
            xytext =(0.8, 0.9), 
            textcoords ='axes fraction',
            arrowprops = dict(facecolor ='black',
                              shrink = 0.05),
            fontsize = 16,
            horizontalalignment ='right'
            verticalalignment ='top')
  
ax.set_title('matplotlib.axes.Axes.broken_barh Example')
  
plt.show()
