How To Make A Line Graph 8 Steps With Pictures

The areas below the X-axis and to the left of the Y-axis represent negative numbers. If your data set doesn’t include negative numbers, you can omit those portions of the graph.

Label several of the lines along each axis with the scale measurements. You don’t need to label every line, but you should space the labeled line at regular intervals along the axis.

Repeat steps 1 and 2 for the next data set, using a different-color pen or a different style of line for each data set. Place an example of the second line color/style in the margin and label it, too. For example, you could use a red pen to graph high temperatures, then use a blue pen to graph low temperatures over the same period on the same graph. Continue repeating steps 1 and 2 for each remaining data set you want to include on the graph.
