Introduction to Graphs and Charts

trends. Most days that hamburger sales go up, cheeseburger sales also go up (with

Graphs
Graphical information may be displayed in many ways. The three basic types of
graphs you should know are: bar graphs, line graphs, and circle graphs (or pie
charts).
Bar Graphs
Bar graphs convert the information in a chart into separate bars or columns. Some
graphs list numbers along one edge, and places, dates, people, or things (individual
categories) along another edge. Always try to determine the relationship between
the columns in a graph or chart.
