Outline
Learning objectives
Get first head view of how data is represented through its
organisation in the form of bar charts.
Get understanding of typical data which can be represented through
bar charts. Also understand the concept of time series.
Get first head feel of the typical question types that are asked on the
basis of bar charts.
Difference bar charts converted include simple bar charts, composite
bar charts, deviation bar charts, stacked bar charts , percentage bar
chars representation on stacked bar charts etc.

1. Simple bar charts
The simple bar charts is the simplest bar charts which has once
continues variable charted along with one discrete variable. Figure
3.1 shows an example

3. Discreate variable Continuous variable
Years Sales (in ₹) trend of a single company
Years Sales (in units) trend of a single company
Years Profit trend of a single company
Years Profit per unit trend of a single company
Years No. of employees trend of a single company
Years Population trend of a single company
Company names Sales of each company for a particular year

2. Stacked bar charts
The length of a bar, on a bar charts, normally represent the
magnitude of a single continuous variable, however. In certain cases
it might be feasible and in the fact required to he breck up to
magnitude of the main continuous variable into its component parts.
When this short of representation is used the charts formed is called
a stacked bar charts.
Different shades , colour, etc. are used to distinguish the various
component and an index is given along with the charts to explain
these differences figure 3.2 gives an example.

4. 3. Composite bar charts
One of the primary limitation of the simple bar charts is that it can
only be used to display a single continuous variable. Similarly,
although a stack/component bar charts can display multiple
continuous variable it can only do so if all the continuous variable
add up to a single continuous variable in the other words, it can be
only display one continuous variable and constituent parts.
However, if two or more sets of continuous variable are to be shown
on the same bar charts figure 3.3 Wil make it clear



4. The use of bar charts to show deviations
Deviation bars are useful for graphic presentation of continuous
variable which can have both positive and negative values, i.e.,
surplus of deficit, net profit and loss, net of imports and exports. In
general continuous variable which have both positive and negative
value are the best represented on bar charts.
A base line is created and positive value (such as profit, surplus), etc.,
Are represented by bar below of bade above the base line. Figure 3.4
will be make it clear.

5. 5. Representation of percentage on a stacked
bar charts
Sometimes stacked bars can also be used to represent the break-up
of some continuous variable. Figure 3.5 will make it clear
Such a use of bar charts its break-up of the various sources of
revenue for the government of India over a two year period.
