Exercise 11: WAP to Draw 3D Bar Graph. (In this program, we will draw a 3D bar graph. Here, we will use line, setfillstyle and bar3d functions to draw horizontal and vertical axis and bars on screen.)

#include <graphics.h>
#include <conio.h>

void main() {
    int gd = DETECT, gm;
    initgraph(&gd, &gm, "c:\\Turboc3\\BGI");
	
    settextstyle(BOLD_FONT,HORIZ_DIR,2);
    outtextxy(275,0,"3D BAR GRAPH");
    setlinestyle(SOLID_LINE,0,2);
    /* Print X and Y Axis */
    line(90,410,90,50);
    line(90,410,590,410);
    line(85,60,90,50);
    line(95,60,90,50);
    line(585,405,590,410);
    line(585,415,590,410);
 
    outtextxy(65,60,"Y");
    outtextxy(570,420,"X");
    outtextxy(70,415,"O");
 
    /* Print 3D bars */
    setfillstyle(XHATCH_FILL, RED);
    bar3d(150,80,200,410, 15, 1);
    bar3d(225,100,275,410, 15, 1);
    bar3d(300,120,350,410, 15, 1);
    bar3d(375,170,425,410, 15, 1);
    bar3d(450,135,500,410, 15, 1);
 
    getch();
    closegraph();
