Plot with Characters or Icons#
Characters#
Blocks could be Unicode characters instead of rectangles by passing the desired character to characters.
Categories could have different character for each category, by passing a list or tuple of characters to parameter characters . The length must be the same as values.
fig = plt.figure(
FigureClass=Waffle,
rows=5,
values=[30, 16, 4],
colors=["#4C8CB5", "#B7CBD7", "#C0C0C0"],
characters='⬤',
font_size=24
)
To specify the font, pass the absolute path to a .ttf or .otf file to parameter font_file.
Icons#
Waffle Chart with icons is also known as Pictogram Chart.
PyWaffle supports plotting with icons through Font Awesome. See page Font Awesome Integration for how Font Awesome is integrated into PyWaffle.

Icon Size#
When using icons, the parameters for setting block size would be ignored, including interval_ratio_x, interval_ratio_y and block_aspect_ratio. Instead, use font_size to set the size of icons. For allowed sizes, see FontProperties.set_size.
fig = plt.figure(
FigureClass=Waffle,
rows=5,
values=[30, 16, 4],
colors=["#232066", "#983D3D", "#DCB732"],
icons='star',
font_size=24
)
Icons in Legend#
Each category could have a different icon, by passing a list or tuple of icon names to parameter icons. The length must be the same as values.
In Font Awesome Icons, there are different icon sets in different styles, including Solid, Regular and Brands. It can be specified through parameter icon_style. By default it searches icon from solid style.
With icon_legend=True, the symbol in legend would be the icon. Otherwise, it would be a color bar.
fig = plt.figure(
FigureClass=Waffle,
rows=5,
values=[30, 16, 4],
colors=["#FFA500", "#4384FF", "#C0C0C0"],
icons=['sun', 'cloud-showers-heavy', 'snowflake'],
font_size=20,
icon_style='solid',
icon_legend=True,
legend={
'labels': ['Sun', 'Shower', 'Snow'],
'loc': 'upper left',
'bbox_to_anchor': (1, 1)
}
)
Specify Icon Style for Each Category#
Font Awesome locates icons by both of icon name and style. Thus, icon style might not be the same for all icons, and you have to specify icon style for all icons separately. Therefore, icon_style also accepts a list or a tuple of styles in string.
fig = plt.figure(
FigureClass=Waffle,
rows=5,
values=[30, 16, 4],
colors=["#FFA500", "#4384FF", "#C0C0C0"],
icons=['sun', 'cloud-showers-heavy', 'font-awesome'],
icon_size=20,
icon_style=['regular', 'solid', 'brands'],
icon_legend=False,
legend={
'labels': ['Sun', 'Shower', 'Flag'],
'loc': 'upper left',
'bbox_to_anchor': (1, 1)
}
)
