The main difference between the subdivided bar diagram and
percentage bar diagram is that in the former the bars are of different
heights since their totals may be different whereas in the latter the
bars are of equal height since each bar represents 100 percent. In
the case of data having subdivision, percentage bar diagram will
be more appealing than subdivided bar diagram.

In onedimensional diagrams, only length 9 is taken into
account. But in twodimensional diagrams the area represent the
data and so the length and breadth have both to be taken into
account. Such diagrams are also called area diagrams or surface
diagrams. The important types of area diagrams are:
1. Rectangles
2. Squares 3. Piediagrams
Rectangles:
Rectangles are used to represent the relative magnitude of
two or more values. The area of the rectangles are kept in
proportion to the values. Rectangles are placed side by side for
comparison. When two sets of figures are to be represented by
rectangles, either of the two methods may be adopted.
We may represent the figures as they are given or may
convert them to percentages and then subdivide the length into
various components. Thus the percentage subdivided rectangular
diagram is more popular than subdivided rectangular since it
enables comparison to be made on a percentage basis.
