1 Line Graphs

2 Line Graphs A line graph compares quantitative data for one or more categories over a period of time, for example:

3 Number of Cases of Lead Exposure
Time Period: Quantitative Data: Year Number of Cases of Lead Exposure 1987 1044 1988 789 1989 884 1990 653 1991 690 1992 807 1993 1900 1994 1995 1718 1996 1382 1997 1156 X Axis Time Period Y Axis Quantitative Data
