What is a segmented bar graph?

A segmented bar graph is similar to regular bar graph except the bars are made of different segments that are represented visually through colored sections. A segmented bar graph is sometimes known as a stacked bar graph, and it offers greater detail about data sets.

Segmented bar graphs are usually used to show the makeup of data, such as the genders or races of a group of students. Each bar in a segmented bar graphs is typically the same length because the focus is on the makeup and values within the bar rather than the whole. If the data is showing a comparison between two different sets of values within the same category, a regular bar graph or line graph is more effective.
