The rectangular method of diagrammatic presentation is
difficult to use where the values of items vary widely. The method
of drawing a square diagram is very simple. One has to take the
square root of the values of various item that are to be shown in the
diagrams and then select a suitable scale to draw the squares.
Yield of rice in Kgs. per acre of five countries are
U.S.A Australia U.K
Yield of rice
in Kgs per 6400
Represent the above data by Square diagram.
4900 Solution: To draw the square diagram we calculate as follows:
Square root Side of the
square in cm
3.5 4 cm
USA 2.5 cm AUST UK 3 cm CANADA 3.5 cm INDIA Pie Diagram or Circular Diagram:
Another way of preparing a two-dimensional diagram is in
the form of circles. In such diagrams, both the total and the
component parts or sectors can be shown. The area of a circle is
proportional to the square of its radius.
While making comparisons, pie diagrams should be used on a
percentage basis and not on an absolute basis. In constructing a pie
diagram the first step is to prepare the data so that various
components values can be transposed into corresponding degrees
on the circle.
The second step is to draw a circle of appropriate size w...
