PyWaffle is an open source, MIT-licensed Python package for plotting waffle charts.
It provides a Figure constructor classWaffle, which could be passed to matplotlib.pyplot.figure and generates a matplotlib Figure object.

importmatplotlib.pyplotaspltfrompywaffleimportWafflefig=plt.figure(
FigureClass=Waffle, rows=5, columns=10, values=[48, 46, 6],
figsize=(5, 3)
)
plt.show()
The values are automatically scaled to 24, 23 and 3 to fit 5 * 10 chart size.
FigureClass and figsize are parameters of matplotlib.pyplot.figure, you may find the full parameter list on matplotlib.pyplot.figure function reference.
Other parameters, including rows, columns, and values in this example, are from Waffle, and see PyWaffle's API Reference for details.
data= {'Cat1': 10, 'Cat2': 7, 'Cat3': 9}
fig=plt.figure(
FigureClass=Waffle,
rows=5,
values=data,
legend={'loc': 'upper left', 'bbox_to_anchor': (1.05, 1)},
)
plt.show()
In this example, only rows is specified and columns is empty, absolute values in values are used as block numbers. Similarly, rows could also be optional if columns is specified.
If values is a dict, the keys will be used as labels in the legend.
data= {'Car': 58, 'Pickup': 21, 'Truck': 11, 'Motorcycle': 7}
fig=plt.figure(
FigureClass=Waffle,
rows=5,
values=data,
colors=["#C1D82F", "#00A4E4", "#FBB034", '#6A737B'],
title={'label': 'Vehicle Sales by Vehicle Type', 'loc': 'left'},
labels=[f"{k} ({v}%)"fork, vindata.items()],
legend={'loc': 'lower left', 'bbox_to_anchor': (0, -0.4), 'ncol': len(data), 'framealpha': 0},
starting_location='NW',
vertical=True,
block_arranging_style='snake'
)
fig.set_facecolor('#EEEEEE')
plt.show()
Parameter colors allows you to change the block color, and it accepts a list of colors that matplotlib can recognize, including hex, RGB in tuple, single character notation, etc. See Matplotlib Colors for details.
Parameter title and legend accept the same parameters as in Matplotlib, matplotlib.pyplot.title and matplotlib.pyplot.legend.
Parameter starting_location, vertical, and block_arranging_style controls Where to Start First Block, Plotting Direction, and Where to Start Each Category.
You may find more details under Examples section in PyWaffle Documentation.

PyWaffle supports Font Awesome icons in the chart. See Plot with Characters or Icons for details.
