Definition of a Bar graph. A bar graph is a chart that uses bars to show comparisons between categories of data. The bars can be either horizontal or vertical. Bar graphs with vertical bars are sometimes called vertical bar graphs. A bar graph will have two axes. One axis will describe the types of categories being compared, and the other will have numerical values that represent the values of the data.
A bar graph can be plotted both vertically, which is sometimes referred to as a column bar graph, or horizontally. Bar charts also resemble histograms, which can display a record of continuous data, but the main difference is the type of data that is represented in the two. Learn more about Data Graphs
