Microsoft QuickC Version 2.00 does not support three-dimensional
charts with the Presentation Graphics package. The on-line help
incorrectly states that the pie-chart Style 2 is a three-dimensional
chart. The Feature Comparison data sheet available from the Microsoft
Sales line, (800) 426-9400, prior to May 1989, also incorrectly states
that the Presentation Graphics package supports three-dimensional
charts.

The reference to three-dimensional charts can be found on Page 149 of
the "Microsoft Graphics Library Reference" manual. It can also be
found by invoking on-line help on _pg_defaultchart and bringing up the
description.

When the following program is compiled, linked, and run, it is easy to
see that both of the pie-chart styles are identical:

#include <conio.h>
#include <stdlib.h>
#include <graph.h>
#include <string.h>
#include <pgchart.h>

#define COUNTRIES 5
float far value[COUNTRIES] =    { 42.5,    14.3,    35.2,   21.3,  32.6    };
char far *category[COUNTRIES] = { "USSR",  "France","USA",  "UK",  "Other" };
short far explode[COUNTRIES] =  { 1,       1,       1,      0,     0       };

main()
{
   chartenv env;
   _setvideomode( _VRES16COLOR );               /* VGA graphics mode       */

   _pg_initchart();                             /* Initialize chart system */

   _pg_defaultchart( &env, _PG_PIECHART, 1 );   /* pie chart style 1       */
   strcpy( env.maintitle.title, "Widget Production" );
   _pg_chartpie( &env, category, value, explode, COUNTRIES );
   getch();

   _pg_defaultchart( &env, _PG_PIECHART, 2 );   /* pie chart style 2       */
   strcpy( env.maintitle.title, "Widget Production" );
   _pg_chartpie( &env, category, value, explode, COUNTRIES );
   getch();

   _setvideomode( _DEFAULTMODE );
}
