You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at. when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?
