Multiple Bars
A multiple bar display is a variant of the mosaicplot that is very closely related to
the fluctuation diagram. Starting from tiles of the same size, the tiles are shrunk to
represent the cell's size. However, unlike fluctuation diagrams, the tiles in multiple
bar displays are shrunk in one dimension only. his makes them look like barcharts.
he structure in the mosaicplot determines the exact layout; switching the order of
the variables (except for the last variable) will shit the smaller barcharts around, but
willnot change theirsizeorappearance. Switchingthelast variable will realign single
bars. In Fig.
.
, the structure underlying the plot is gender, vehicles
′
, age, i.e., the
barcharts display the number of accident victims by age group.here is one barchart
for each combination of vehicle type and gender. Overall, more men than women are
reportedtohaveaccidents. heagedistributions vary alotbetween vehicle types,but
are fairly similar between the two genders, with the exception of motorcycles. A lot
more men than women are involved in motorcycle accidents.
Same-Bin-Size Displays
As the name suggests, the same-bin-size variant of a mosaicplot contains equally
sized bins. his makes the same-bin-size display a mosaicplot with a special form
of weight variable: W
