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.
