Percentage Bar Graph/Diagram

What is a Bar Graph/Bar Diagram?

A Bar graph is a type of data-handling method that is popularly used in statistics. A bar graph or bar chart is a visual presentation of a group of data that is made up of vertical or horizontal rectangular bars with lengths that are equal to the measure of the data....

Types of Bar Graph or Bar Diagram

...

1. Simple Bar Graph/Diagram

The different types of Bar Graphs are as follows:...

2. Multiple Bar Graph/Diagram

A diagram in which each class or category of data is represented by a group of rectangular bars of equal width is known as a Simple Bar Diagram. It is the simplest type of bar diagram. In this diagram, each bar represents one figure only. The number of bars will be equal to the number of figures. These diagrams show only one characteristic of the data, such as sales, production, or population figures for various years....

3. Sub-Divided Bar Graph/Diagram

The Multiple Bar Diagram is used to compare two or more variables such as revenue and expenditure, import and export for different years, marks obtained in different subjects in different grades, and so on. It is often referred to as a Compound Bar Diagram. The method for creating multiple bar diagrams is the same as for making a Simple Bar Diagram. However, to distinguish the bars from each other, different bars are differentiated by different shades or colours....

4. Percentage Bar Graph/Diagram

In these diagrams, the bar corresponding to each phenomenon is divided into several components. Each part or component occupies a proportional part of the bar to its share in the total. For example, the bar corresponding to the number of students enrolled in a course can be further sub-divided into boys and girls....

5. Broken-Scale Bar Graph/Diagram

A Percentage Bar Diagram is a sub-divided bar diagram that indicates the total percentage of each component rather than the magnitude. The absolute magnitudes of several components are presented using a subdivided diagram. These magnitudes can be converted into relative values by describing them as a percentage of the total....

6. Deviation Bar Graph/Diagram

This diagram is used when the value of one variable is extremely high or extremely low compared to others. Larger bars may be broken to make space for the smaller bars of the series. Every bar has its value written on the top of the bar....

Features of Bar Graph/Diagram

These diagrams are used to represent net changes in data such as net profit, net loss, net exports, net imports, etc....

Advantages of Bar Graph/Diagram

In this diagram, the magnitude of the characteristics is shown by the length or height of the bar. The width of a bar is arbitrarily set to make the constructed diagram more elegant and attractive. The length and height of the bars vary depending on the variable value. However, the width of the bar remains constant. The width of a bar is also determined by the number of bars that must be accommodated in the diagrams. The bars must be equidistant from one another. Bars can be drawn horizontally or vertically. They are, however, usually in vertical form. The side or vertical axis of a bar graph is called the y-axis and the bottom or horizontal axis of a bar graph is known as the x-axis. The y-axis represents data value, while the x-axis represents data type....

Disadvantages of a Bar Graph/Diagram

Due to their accessibility and suitability for visual data representation, bar diagrams are used across several industries. Following are some of the advantages of bar diagrams:...
