How to Choose Which Type of Graph to Use?
When to Use . . .. . . a Line graph.
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be sued to compare changes over the same period of time for more than one group.
. . . a Pie Chart.
Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.
. . . a Bar Graph.
Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.
Let me know what you think!
