The low-level graphics functions described in Chapter 9, “Communicating with Graphics,” draw points, lines, and shapes. Although it is possible to use these functions to generate charts and graphs, an additional set of high-level graphics functions is better suited to this task.
“Presentation graphics” is a set of high-level functions that displays presentation-quality graphics. These functions transform numeric data into pie charts, bar and column charts, line graphs, and scatter diagrams.
This chapter describes how to use presentation graphics.
