This topic, and the following three topics, describe the Presentation Graphics Routines (PG routines). This topic introduces the use of the PG routines with two program examples. The first is elementary, the second a little more elaborate. The topic also describes briefly the types of business chart that the routines can produce. Finally, the concept of absolute and relative data is discussed, together with the method used by the routines to shade business charts.

• 3.2 Example 2
• 3.3 The nine chart types
• 3.4 Absolute and relative data
• 3.5 How charts are shaded
