不是这个啊！要用曲线函数啊#include#include#include#include#include#includemain(){int gd=DETECT,gm=0;initgraph(&gd,&gm,""); /* 自动检测显示卡，并选用最大分辨率 *//*setfillstyle(SOLID_FILL,2); /* 填充模式为实填充，颜色为棕色 *//*bar(100,100,150,400); /* 绘制二维条形图，TC 2.0 规定屏幕左上角为(1,1)，右下角为(80,25) */line(40,99,40,400);line(40,400,600,400);setfillstyle(SOLID_FILL,1); /* 填充模式为网格线，颜色为绿色 */bar3d(50,250,100,400,20,20);setfillstyle(SLASH_FILL,2);bar3d(150,130,200,400,20,2);setfillstyle(INTERLEAVE_FILL,3);bar3d(250,300,300,400,20,2);setfillstyle(HATCH_FILL,4);bar3d(350,150,400,400,20,2);setfillstyle(XHATCH_FILL,5);bar3d(450,200,500,400,20,2); /* 绘制有三维顶盖的三维条形图 */getch();closegraph(); /* 关闭图形模式,返回字符模式*/}
