函数名: bar
功 能: 画一个二维条形图
用 法: void far bar(int left, int top, int right, int bottom).
程序例:
#include
#include
#include
#include
int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode.
int midx, midy, i.
/* initialize graphics and local variables */
initgraph(&.gdriver, &.gmode, "").
/* read result of initialization */
errorcode = graphresult().
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode)).
printf("Press any key to halt:").
getch().
exit(1). /* terminate with an error code */
}
midx = getmaxx() / 2.
midy = getmaxy() / 2.
/* loop through the fill patterns */
for (i=SOLID_FILL. i
{
/* set the fill style */
setfillstyle(i, getmaxcolor()).
/* draw the bar */
bar(midx-50, midy-50, midx 50,
midy 50).
getch().
}
/* clean up */
closegraph().
return 0.
}

函数名: bar3d
功 能: 画一个三维条形图
用 法: void far bar3d(int left, int top, int right, int bottom,
int depth, int topflag).
程序例:
#include
#include
#include
#include
int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode.
int midx, midy, i.
/* initialize graphics, local variables */
initgraph(&.gdriver, &.gmode, "").
/* read result of initialization */
errorcode = graphresult().
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode)).
printf("Press any key to halt:").
getch().
exit(1). /* terminate with error code */
}
midx = getmaxx() / 2.
midy = getmaxy() / 2.
/* loop through the fill patterns */
for (i=EMPTY_FILL. i
{
/* set the fill style */
setfillstyle(i, getmaxcolor()).
/* draw the 3-d bar */
bar3d(midx-50, midy-50, midx 50, midy 50, 10, 1).
getch().
}
/* clean up */
closegraph().
return 0.
