_pg_getchardef

 

Synopsis : #include <pgchart.h> 

              short _FAR _pg_getchardef( short ch, unsigned char FAR *def );


Description : The _pg_getchardef function retrieves the current bit-map definition for the character ch. The bit-map is placed in the array def. The current font must be an 8-by-8 bit-mapped font.

 

 

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

_pg_getpalette

 

Synopsis : #include <pgchart.h> 

              short _FAR _pg_getpalette( paletteentry _FAR *pal );

 


Description : The _pg_getpalette function retrieves the internal palette of the presentation graphics system. The palette controls the colors, line styles, fill patterns and plot characters used to display each series of data in a chart.


The argument pal is an array of palette structures that will contain the palette. Each element of the palette is a structure containing the following fields:

 fields  Meaning
 color  color used to display series
 style  line style used for line and scatter charts
 fill  fill pattern used to fill interior of bar and pie sections
 plotchar  character plotted on line and scatter charts

 

 

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

#include <graph.h>

#include <string.h> 

#include <conio.h>


#define NUM_VALUES     4


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


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


char bricks[8] = { 0xff, 0x80, 0x80, 0x80, 0xff, 0x08, 0x08, 0x08 };


main( )

{
    chartenv env;

    palettetype pal;


    _setvideomode( _VRES16COLOR );

    _pg_initchart( );

    _pg_defaultchart ( &eny, _PG_COLUMNCHART, _PG_PLAINBARS ); 

    strcpy( env.maintitle.title, "Column Chart" );

 

    /* get default palette and change ist entry */

    _pg_getpalette( &pal );

    pal[1].color = 12;

    memcpy( pal[1].fill, bricks, 8 );

 

    /* use new palette */

    _pg_setpalette( &pal );

    _pg_chart( &eny, categories, values, NUM_VALUES );

 

    /* reset palette to default */

_pg_getstyleset

 

Synopsis : #include <pgchart.h> 

              void _FAR _pg_getstyleset( unsigned short _FAR *style );

 


Description : The _pg_getstyleset function retrieves the internal style-set of the presentation graphics system. The style-set is a set of line styles used for drawing window borders and grid-lines. The argument style is an array that will contain the style-set.

 

 

Returns : The _pg_getstyleset function does not return a value.

    /* turn on yaxis grid, and use style 2 */

    env.yaxis.grid = 1;

    env.yaxis.gridstyle = 2;

 

    /* get default style-set and change entry 2 */

    _pg_getstyleset( &style );

    style[2] = 0x8888;

 

    /* use new style-set */

    _pg_setstyleset( &style );

    _pg_chart( &eny, categories, values, NUM_VALUES );

_pg_hlabelchart

 

Synopsis : #include <pgchart.h> 

              short _FAR _pg_hlabelchart( chartenv _FAR *env,

                                             short x, short y,

                                             short color,

                                             char _FAR *label );


Description : The _pg_hlabelchart function displays the text string label on the chart described by the env chart structure. The string is displayed horizontally 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_hlabelchart function returns zero if successful; otherwise, a non-zero value is returned.
