How to Plot a Line Graph

If you are interested in plotting a line graph, there are plenty of sites on the Internet that provide free line plotting calculators. Some offer basic line plotting features, while others offer a range of graphic format features. Most are pretty simple to learn and use. Teachers, parents and students might find that they are excellent teaching tools as well.

      Draw a vertical line through the center of your graph paper that starts at the bottom edge of the paper and ends at the top edge of the paper. Label this line as the "y-axis." Ensure that the y-axis is drawn directly over a vertical grid line on the graph paper.

    • 2

      Draw a horizontal line through the center of your graph paper that starts at the left edge of the paper and ends at the right edge of the paper. Label this line as the "x-axis." Ensure that the x-axis is drawn directly over a horizontal grid line on the graph paper.

    • 3

      Label the point where the x-axis and the y-axis intersect as point "P(0,0)." Label the point where the first vertical line on the graph paper to the right of the y-axis intersects the x-axis with a "1." Label the next intersection to the right as "2." Continue marking points on the x-axis in this manner until you reach 10.

    • 4

      Label the point where the first horizontal line on the graph paper above the x-axis intersects the y-axis with the number "1." Label the next intersection up as "2." Continue marking points on the y-axis in this manner until you reach 10.

      Plot the following list of seven paired (x,y) points on the graph paper. Draw each point at the intersection of a line drawn vertically up from the x-coordinate and the intersection of a line drawn horizontally through the y-coordinate of the (x,y) paired data point used.

      (0,0), (1,1), (5, 3), (3, 1), (5, 8), (6, 9), and (7,3)

      Verify that your line graph has been plotted correctly with an online line graph calculator. Use the one listed in the resources section as "National Center for Education Statistics; Kids' Zone; Create a Graph" to not only plot your line graph but format it to.
