3. Graphic presentation of fiscal reports is an effective way to show information. Line graphs and curve charts are particularly adaptable to:

a. Show the analyses of the elements of cost over a period of time. b. Designate the trend of costs over a period of time. c. Demonstrate the difference in quantitative units for two or more different types of data which are to be shown on the same charts. d. Compare and show elements of cost for a given unit of service at any particular time.
