Multiple bar diagram

Multiple bar diagram


    • If the data is classified by attributes and if two or more characters or groups are to be compared within each attribute we use multiple bar diagrams. If only two characters are to be compared within each attribute, then the resultant bar diagram used is known as double bar diagram.

    • The multiple bar diagram is simply the extension of simple bar diagram. For each attribute two or more bars representing separate characters or groups are to be placed side by side. Each bar within an attribute will be marked or coloured differently in order to distinguish them. Same type of marking or colouring should be done under each attribute. A footnote has to be given explaining the markings or colourings.

    Example

    Draw a multiple bar diagram for the following data which represented agricultural production for the priod from 2000-2004
    Year Food grains (tones) Vegetables (tones) Others (tones)
    2000 100 30 10
    2001 120 40 15
    2002 130 45 25
    2003 150 50 25
    2004
