Line . . . Line . . . Line

The rain in Spain stays mainly on the plain.  The temperature in New York apparently is rising from this line graph.


This line graph is showing the temperature over a certain period of TIME.  In line graphs, you will always find TIME on the horizontal axis.  If you ever are dealing with data over a period of TIME, line graphs are a very logical way to display your data.  Bar graphs are for "One Moment in Time" and to compare different categories.  Line graphs are for a single category over a period of TIME (did you catch that subtle hint).
