Bar Graphs

Back Back to Charts

Bar graphs are similar to column graphs, except the bars run horizontally rather than vertically. These charts compare groups at a single point in time. For example, a bar graphs would accurately depict the number of African Americans, Asian Americans, Native Americans, and Hispanic Americans in the 1982 Congress.

Visually-effective bar charts should be spaced as follows:

  • 1/2 bar width between single bars and
  • one bar width between grouped bars.
