What is a Segmented Bar Graph?

A segmented bar graph, also referred to as a stacked bar chart, is a graphical representation of categorical data. It displays information by dividing a bar into segments, each representing a particular category. The length or height of each segment corresponds to the quantity of that category within the total data set.

Segmented Bar Graph vs. Other Charts

Segmented Bar Graph vs. Mosaic Plot

While both are used for visualizing categorical data, there's a difference between a segmented bar graph and a mosaic plot. A segmented bar graph portrays multiple data categories in individual bars, with the size of segments representing values. On the other hand, a mosaic plot uses area to represent proportions, effectively combining a segmented bar graph and a two-way frequency table.

Segmented Bar Graph vs. Stacked Bar Chart

The terms segmented bar graph and stacked bar chart are often used interchangeably. Both display data in segments within a bar, representing different categories. However, the difference lies in their presentation. In a stacked bar chart, segments are placed on top of each other, forming a single bar. In a segmented bar graph, segments can be horizontally aligned side by side, although they're often vertically stacked, leading to the confusion.

How to Create a Segmented Bar Graph?

Creating a segmented bar graph can be accomplished in various software tools, with Excel and Google Sheets being two of the most common.

Creating a Segmented Bar Graph in Excel

To create a segmented bar graph in Excel, input your data in rows or columns on the worksheet. From there, select the data and choose the "Stacked Bar" or "

Stacked Column" chart from the "Insert" tab. This will generate a segmented bar graph, which can be further customized.

Creating a Segmented Bar Graph in Google Sheets

Similarly, to create a segmented bar graph in Google Sheets, enter your data in rows or columns. Once your data is selected, go to "Insert," then "Chart," and finally select the "Stacked Bar Chart" or "Stacked Column Chart" option. You can adjust the colors and labels as needed.

Why Use a Segmented Bar Graph?

Segmented bar graphs are valuable tools in data visualization. They allow for quick comparison of different data categories, showing their individual contributions to the total data set. They're excellent for comparing parts to a whole and tracking changes over time. Furthermore, they can help determine if there's an association between categorical variables in a data set.


In conclusion, segmented bar graphs are essential tools for data visualization. They help communicate complex data in an easily digestible format. By understanding and mastering the use of these charts, you can effectively present your data and derive valuable insights.

Segmented Bar Graph FAQs

Here are a few frequently asked questions (FAQs) about segmented bar graphs:

  1. What are the advantages of using a segmented bar graph? Segmented bar graphs provide a clear visualization of how each category contributes to the overall total. They're great for comparing parts to a whole, and they're easy to read and interpret.

  2. How do I tell if there's an association in a segmented bar graph? If the proportions of categories within the segments change significantly across the bars, there may be an association between the variables.

  3. How does a segmented bar graph differ from a grouped bar chart? A segmented bar graph divides a single bar into segments representing different categories, while a grouped bar chart displays each category as a separate bar.
