Question

How is a line graph different from a bar graph?

Answer 1

A line graph is used to compare changes over the same period of time, it's when you join points by drawing straight lines.

A bar graph compares things between two different groups, it's when you draw columns that correspond to the numbers to compare results.

Answer 2

Line graphs can also be used to compare changes over the same period of time for more than one group. Bar graphs are used to compare things between different groups or to track changes over time.
