How to create broken horizontal bar graphs in matplotlib?
To create broken horizontal bar graphs in matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a figure and a set of subplots.
- Plot a horizontal sequence of rectangles.
- Scale X and Y axes limit.
- Configure the grid lines.
- Annotate the broken bars.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
fig, ax = plt.subplots()
# Horizontal sequence of rectangles
ax.broken_barh([(110, 30), (150, 10)], (10, 9), facecolors='tab:blue')
ax.broken_barh([(10, 50), (100, 20), (130, 10)], (20, 9),
facecolors=('tab:orange', 'tab:green', 'tab:red'))
# Scale X and Y axes limits
ax.set_ylim(5, 35)
ax.set_xlim(0, 200)
# Configure the grid lines
ax.grid(True)
# Annotate the broken bars
ax.annotate('race interrupted', (61, 25),
xytext=(0.8, 0.9), textcoords='axes fraction',
arrowprops=dict(facecolor='black', shrink=0.05),
fontsize=16,
horizontalalignment='right', verticalalignment='top')
plt.show()Output
It will produce the following output
