2. Line graphs Line graphs can be useful for showing the results of an experiment. You usually use a line graph when you have to show two sets of measurements. Line graphs can be useful for showing the results of an experiment. You usually use a line graph when you have to show two sets of measurements. Here are the results of an experiment to find out how long a spring is when it has different forces on it.

5. Working out the scale First, look at your table of results and work out the largest number that has to go on each axis. First, look at your table of results and work out the largest number that has to go on each axis. Now count the squares on your graph paper. If there are not enough, try again, counting in 2s, or 5s, or 10s, until you find a scale that fits on the paper. Now count the squares on your graph paper. If there are not enough, try again, counting in 2s, or 5s, or 10s, until you find a scale that fits on the paper. The first column of a table usually goes on the bottom (horizontal, x ) axis. The first column of a table usually goes on the bottom (horizontal, x ) axis. Now plot the results from the spring experiment on graph paper. Now plot the results from the spring experiment on graph paper.

6. Two sets of results Sometimes you might want to put two sets of results on your graph so that you can compare them. Sometimes you might want to put two sets of results on your graph so that you can compare them. You can draw the two lines in different colours, or use different symbols for the points and put a key on your graph. You can draw the two lines in different colours, or use different symbols for the points and put a key on your graph. Now plot a graph showing the temperatures inside the cars. Don’t forget to put a title on your graph. Now plot a graph showing the temperatures inside the cars. Don’t forget to put a title on your graph.
