How to make a Bar Graph



You make a bar graph by first making designing a grid. Next, you number the left vertical side by either 1,2,3,4,5,6,7,8,9,10, or another number. Then you make bars vertically in the center of a graph. The bars should represent the variables and should climb to the amount on the left numbers. Last you label the variables on the bottom of the graph. Your bar graph should look like the image above.
