How to graph When graphing, you must remember the following: Title Label the x and y axis For line graphs: the dependent variable is on the y-axis and independent variable goes on the x-axis For bar graphs: the names of items go on the x-axis, and the amounts and units of measure go on the y-axis. Use even numerical spacing Even graphical spacing Be accurate and neat Use rulers, protractors, and colors as necessary
