[<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
_pg_hlabelchart() Write horizontal chart label
#include <pgchart.h>
short _pg_hlabelchart(env, x, y, color, label);
chartenv _far *env; Chart environment
short x; X coordinate (pixels)
short y; Y coordinate (pixels)
short color; Color index for text
char _far *label; Label to write
_pg_hlabelchart() writes a horizontal label, as stored in the string
label on the screen starting at pixel (x, y) relative to the upper
left of the chart window. It is valuable for placing labels anywhere
you need them on a chart. In the following example, we label the two
lines in a multiseries line chart.
Returns: 0 for success; nonzero otherwise.
Portability: MS-DOS only, true MDPA, CGA, EGA, MCGA, or VGA video
compatibles
-------------------------------- Example ---------------------------------
This program puts a variety of Presentation Graphics charts on the
screen.
