Bar Graphs are the representation of data using horizontal or vertical bars, where the length of the bars generally represent the measure of the data. The length of the bars represent the numerical value of the data. It is used in statistical representation of data, data handling and interpretation. 


The bars drawn should be of equal width. In one of the axes (usually x-axis), the variable quantity is written and depicted. In the other axis (usually y-axis), the measure of the variable quantity is written. The lengths of the bars are used to denote the measure of the quantities. Usually, bar graphs are used to compare quantities of given information. 


Features of a Bar Graph:

  1. A bar graph generally contains two axes (x-axis and y-axis), scales of the axis, bars and a title of the graph.

  2. Bar graphs help to compare different sets of data. 

  3. Some bar graphs also have legends, which are used to represent different sets of data in one graph. 

  4. In a bar graph, the data is spread over two axes, categories on one axis and the values in the other axis. 

  5. Bar graphs can show major changes over time.

  6. The bars of the graph should have a common base.

  7. The distance between any two bars should always be equal.

  8. Each bar should be of the same width. 

  9. The height of the bar should conform with the corresponding value. 


Types of Bar graphs

When presenting data visually, we have a lot to consider in bar graphs.


The different types of Bar Graphs are:

  • Vertical Bar Graphs

  • Horizontal Bar Graphs

  • Grouped Bar Graphs

  • Stacked Bar Graphs


Let us discuss the types of bar graphs in detail.

  1. Vertical Bar Graphs- This is the most common type of bar graph used. In this, the grouped data is represented vertically, with the help of bars, where the bars denote the data. One disadvantage of vertical bar graphs is that they don’t leave lots of space at the bottom, so long labels, if required, cannot be put in.

  2. Horizontal Bar Graphs- The grouped data is represented horizontally, with the help of bars, where they denote data. Here, the data is represented along the x-axis. 

  3. Grouped Bar Graphs - The grouped bar graphs are also known as clustered bar graphs. Here, data of more than one object which shares the same category are represented. An aggregate of instances are combined in one bar graph and displayed. In a grouped bar graph, a specific colour is used to denote a single instance in the graph. 

  4. Stacked Bar Graphs- In this type of bar graph, each part is represented using colours, which makes it easier to identify. The stacked bar chart is labelled to differentiate the segments of the graph. 

FAQs on RD Sharma Class 6 Maths Solutions Chapter 23 - Data Handling III (Bar Graphs)

1. What is a bar graph?

A bar graph is the statistical representation of data using bars. Bar Graphs are one of the easiest ways to explain sophisticated statistical information. Bar graphs are ideal for comparing discrete values of two or more objects of the same category. When a graph has a well defined zero point, we can easily understand the difference of the position of the positive and negative values. For the x-axis, the values to the right of the zero point are the positive values, and to the left of the zero point are the negative values. For the y-axis, the values above the zero point are the positive values, while values below the zero point are the negative values.

2. What are the advantages and disadvantages of bar graphs?

The advantages of bar graphs are:

  • Bar graphs help in assembling and interpreting a large set of data in simple, visual form.

  • Frequency distribution tables can easily be established in a pictorial form using bar graphs. 

  • Readers can get an idea of the data at a glance. 

  • Bar Graphs are more easily readable and easy to interpret, amongst other pictorial charts. 


The disadvantages of using bar graphs are:

  • Sometimes, the data is so large that interpreting it using a bar graph becomes problematic. 

  • Improper usage of legends and keys can give out wrong information.

  • Wrong scale information can change the value of the entire graph. 

3. What are the uses of bar graphs?

Since bar graphs are so easy to use and read, they are used for a number of purposes. They are used to trace changes between categories, or over a period of time. Bar Graphs are the most suitable when the change over a period of time is big. 


Bar Graphs are usually scaled and drawn in such a way that big data also fits on a small graph. Bar graphs help readers to understand large data easily and quickly.

4. How to draw a Bar Graph?

The steps to draw a Bar Graph are:

  • Deciding on the title of the Bar Graph. 

  • Drawing both the axes and labelling them.

  • Noting down the data for both the axes.

  • Writing down the scale for both the axes.

  • Drawing the Bar Graph with respect to the categories. 

These are just a few steps. For more elaboration, visit the Vedantu app or website. The study materials there shall guide the student to understand the topic and gain insights on it.
