Create Waffle Chart Visualizations
Square pie charts (a.k.a. waffle charts) can be used to communicate parts of a whole for categorical quantities. To emulate the percentage view of a pie chart, a 10x10 grid should be used with each square representing 1% of the total. Modern uses of waffle charts do not necessarily adhere to this rule and can be created with a grid of any rectangular shape. Best practices suggest keeping the number of categories small, just as should be done when creating pie charts. Tools are provided to create waffle charts as well as stitch them together, and to use glyphs for making isotype pictograms.
It uses ggplot2 and returns a ggplot2 object.
The master
branch is the stable branch of waffle
.
The current in-development branch is 1.0.0
if you want to play with bleeding edge features (like the new waffle geom).
The following functions are implemented:
waffle
: make a waffle chart ggplot2 objectiron
: vertically stitch together multiple waffle plots, left-aligning edges (best if used with thewaffle
pad
parameter)fa_grep
: Search FontAwesome names for a pattern- `fa_list: List all FontAwesome names

With:
iron(

waffle(c(thing1 = 25, thing2 = 75), rows = 5)

Without (you can disable this via keep
parameter now):
iron(
waffle(c(thing1 = 0, thing2 = 100), rows = 5, keep = FALSE),
waffle(c(thing1 = 25, thing2 = 75), rows = 5, keep = FALSE)
)
