_pg_defaultchart

Description

Initializes the chart environment.

#include <pgchart.h>

short __far _pg_defaultchart( _chartenv __far *env, short charttype,
short chartstyle );

Remarks

The _pg_defaultchart function initializes all necessary variables in the chart environment for the chart type by the variable charttype.

All title fields in the environment structure are blanked. Titles should be set in the proper fields after calling _pg_defaultchart.

The charttype variable can be set to one of the following manifest constants:

The chartstyle variable specifies the style of the chart with either the number “1” or the number “2.” Each of the five types of presentation-graphics charts can appear in two different chart styles, as described below:

In a pie chart, the pieces are “exploded” according to the explode array argument in the _pg_chartpie function. In the “percent” format, percentages are printed next to each slice. Bar and column charts have only one style when displaying a single series of data. The styles “side by side” and “stacked” are applicable only when more than one series appears on the same chart. The first style arranges the bars or columns for the different series side by side, showing relative heights or lengths. The stacked style emphasizes relative sizes between bars and columns.

Return Value

The _pg_defaultchart function returns 0 if there were no errors. A nonzero value indicates a failure.
