Bar Graphs The simplest and and most straightforward way to compare various categories is the classic bar graph. The universally-recognized graph features a series of bars of varying lengths. One axis of a bar graph features the categories being compared, while the other axis represents the value of each.

Bar charts are one of the most common data visualizations. You can use them to quickly compare data across categories, highlight differences, show trends and outliers, and reveal historical highs and lows at a glance. Bar charts are especially effective when you have data that can be split into multiple categories.

A multi-level category chart can display both the main category and subcategory labels at the same time. When you have values for items that belong to different categories and want to distinguish the values between categories visually, this chart can do you a favor.

A grouped bar chart (aka clustered bar chart, multi-series bar chart) extends the bar chart, plotting numeric values for levels of two categorical variables instead of one. Bars are grouped by position for levels of one categorical variable, with color indicating the secondary category level within each group.

When you should use a bar chart From a bar chart, we can see which groups are highest or most common, and how other groups compare against the others. Since this is a fairly common task, bar charts are a fairly ubiquitous chart type. The primary variable of a bar chart is its categorical variable.
