这是我的代码。它应该在每次循环 main 时绘制一个条形图。它最初正确显示条形图，但是当循环时，线条功能似乎不再起作用....有人可以帮我吗？此处提供的图形库：http ://www.mediafire.com/file/qtdy239vvr19qyi/CODE+BLOCKS+with+Graphic.h.rar 注意：我使用的是代码块 17.12

#include <graphics.h>

using namespace std;

void graph(string f){
   cleardevice();

settextstyle(BOLD_FONT,HORIZ_DIR,2);
 outtextxy(275,0, "BAR CHART");

setlinestyle(SOLID_LINE,0,2);
