Line Graphs Intro Line graphs show the change in something by drawing a line to connect dots that show values. Line graphs are very good at showing changes over time. For example if you wanted to graph the number of times you through different balls through a hoop and showed your score out of ten it would look something like this 1.First you must have something you want to graph in this example, we graphed the score out of ten we got by throwing different balls through a hoop. You need to have variables in your graph, or it won’t be very good. One thing you could graph is the temperature on different days to find out the weather pattern of your area. Up and along the side their needs to be some sort of numbers that represent something so you can have your lines go up and down to show the difference. These numbers are usually time, people, or scores. Then you need to have something along the bottom this is what you are going to compare. 2.Now that you have something you want to graph you can perform your tests or gather your information for your graph. Make each variable a word along the bottom the variables in our example chart are the different balls. Each variable should be made a dot on the line of the appropriate number for example if you were graphing the temperatures of different days and on one day the temperature was 98 degrees you would put a dot on the 98 line. Each dot should be exactly one line over from the next. 3.Now your almost done all you have to do is connect the dots in order from left to right. Make sure your graph has a title and your variables all have names. Also make sure your variables have a title like in our example chart we used different balls thrown through a hoop so we would give them the title of Balls thrown and make sure your numbers have a title also explaining what they are. That’s it your done.
