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.
