Synopsis:
    #include <pgchart.h>
    short _FAR _pg_vlabelchart( chartenv _FAR *env,
                                short x, short y,
                                short color,
                                char _FAR *label );

Description:
    The _pg_vlabelchart function displays the text string label on the chart
    described by the env chart structure.  The string is displayed
    vertically starting at the point (x,y), relative to the upper left
    corner of the chart.  The color specifies the palette color used to
    display the string.

Returns:
    The _pg_vlabelchart function returns zero if successful; otherwise, a
    non-zero value is returned.

Example:
    #include <graph.h>
    #include <pgchart.h>
    #include <string.h>
    #include <conio.h>

    #if defined ( __386__ )
        #define _FAR
    #else
        #define _FAR    __far
    #endif

    #define NUM_VALUES 4

    char _FAR *categories[ NUM_VALUES ] = {
        "Jan", "Feb", "Mar", "Apr"
    };

    float values[ NUM_VALUES ] = {
        20, 45, 30, 25
    };

    main()
    {
        chartenv env;

        _setvideomode( _VRES16COLOR );
        _pg_initchart();
        _pg_defaultchart( &env,
                          _PG_COLUMNCHART, _PG_PLAINBARS );
        strcpy( env.maintitle.title, "Column Chart" );
        _pg_chart( &env, categories, values, NUM_VALUES );
        _pg_hlabelchart( &env, 64, 32, 1, "Horizontal label" );
        _pg_vlabelchart( &env, 48, 32, 1, "Vertical label" );
        getch();
        _setvideomode( _DEFAULTMODE );
    }
