Question

What is a sub divided bar diagram?
Draw a sub divided bar diagram from the following data?

Stream	Number of students
	2009	2010	2011
Arts	50	70	75
Science	200	250	300
Commerce	100	120	130

Answer 1

Hint: We first explain the process of creating the chart for a sub-divided bar diagram. The components get represented in a single bar. The representation can also be represented as total stacked.

Complete step by step solution:
A sub-divided bar diagram is used to present the data having 2 or more common components. Subdivided or component bar chart is used to represent data in which the total magnitude is divided into different components.
The two main components for our given problem are year and stream.
We represent the years along X-axis and the streams along Y-axis.
The streams for a single year will be represented in a single bar divided by respective percentages.
The blue coloured parts represent the arts section, brown coloured parts represent the science section and green coloured parts represent the commerce section.

Note:
We always represent the components according to the fractional value or the percentage value. The full stacked representation is also where the total value is the same for all the main components.
