Table is a great way to keep your data organized. But it's not so easy to draw any conclusions by thking a quick glance. A line graph depicts the relationship between the dependent and independent variables. Each variable is plotted along one of the two axes in the graph. The x-axis is the horizontal axis, which usually plots the independent variable. Since your independent variable is time, then you'd plot time in days along the x-axis. The other axis is called the y-axis. This is the vertcal axis that usually plots the dependent variable. So your dependent variable is plant height. You're actually going to have two lines on the graph: one to show the growth of the sunflower plant, and one to show the growth of the daisy. Let's make the sunflower line orange and the daisy line blue. You'll need to add a key to the bottom to show which line describes the growth of which plant.
