A component bar or sub divided bar chart is used to represent data in which total magnitude is divided into different components For Drawing/Constructing it:
We make simple bars representing each component over one another. The total of all components represent the total length of each bar. In order to distinguish the various components of each bar we use different color/Pattern. In this video i have used a data set of students studying in commerce college in different years for constructing it I took year of study at horizontal axis and number of students at vertical axis.
We may also represent component bar chart by percentages. percentage component bar charts and pie charts are best alternate to each other.
