The presentation graphics variable "scaletitle" does not display
labels on axes with nonvalue data. Scaletitle is part of the chart
variable "env". As documented on Page 80 of the "Microsoft QuickC
Graphics Library Reference," scaletitle works correctly only with
value data.

To modify the scaletitle variable, you must copy a string into the
environment as depicted in the following source line:

   strcpy(env.xaxis.scaletitle.title,"Supply vs. Demand");

Scaletitle is of type "titletype", which has the following structure
definition:

typedef struct
{
  char    title[_PG_TITLELEN];     /* Title text */
  short   titlecolor;              /* Palette color for the title */
  short   justify;                 /* _PG_LEFT, _PG_CENTERAL
                                      or _PG_RIGHT */
} titletype;

To unconditionally display axis titles, the variable "axistitle"
should be used instead. The chart functions display these axis titles
whether the axis is of numeric value type or string category type.
