# What is Bar Graph?

A graph represents data by depicting it in rectangular bars of different heights where the length of each bar is proportional to the value they stand for.

Bar graphs are frequently used to represent business data that are independent of one another and – as such – don’t need to be in any specific order while being represented, such as financial results and growth metrics.

Their format is easy to read at a glance as it consists of two lines: horizontal and vertical (the x and y-axis) described with the title, labels, and scale range.

## There are two main types of Bar Graphs:

- Vertical
- Horizontal

However, there is also a subtype that can be used for more complex comparisons:

- Grouped Bar Graph
- Stacked Bar Graph

There are two or more bars of different colors in grouped bar graphs to represent a particular group of data. In stacked bar graphs, bars are on top of each other, and the height of the stack shows the combined result.
