Here is a C program to draw 3D bar chart on screen using graphics.h header file. In this program, we will draw a 3D bar graph on screen. Here, we will use line, setfillstyle and bar3d functions of graphics.h header file to draw horizontal and vertical axis and bars on screen.
It draws a line from (x1, y1) to (x2, y2).
It sets the current fill pattern and fill color.
bar3d function draws a 3D cuboid and fill front facing surface with current fill pattern and color.
Function Argument | Description |
---|---|
xTopLeft | X coordinate of top left corner. |
yTopLeft | Y coordinate of top left corner. |
xBottomRight | X coordinate of bottom right corner. |
yBottomRight | Y coordinate of bottom right corner. |
depth | It specifies the depth of bar in pixels. |
topFlag | It specifies whether a 3D top to put on the bar or not(any non-zero value specifies a 3d top other wise no 3d top). |
C program to draw 3D bar graph using graphics
#include <graphics.h> int main() { int gd = DETECT, gm; initgraph(&gd, &gm, "C:\\TC\\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); closegraph(); return 0; }Output
