VC画坐标轴源程序，很好看

int width=1000;
    int height=300;
int m_rowX=0;

//确定坐标图四周预留的空白大小
    const int mytop=10;
    const int mybottom=40;
    const int myleft=60;
    const int myright=10;
    const int x_distance=15;
//确定X，Y轴每单位显示宽度
    float m_x_num=60,m_y_num=10,m_potY1=5,m_potY2=100;
float intervalX=(width-myleft-myright)/(m_x_num);
float intervalY=(height-mybottom-mytop)/(m_y_num);

//确定显示刻度个数
float bottomY=0;
    float leftX=0;
const int count_x=m_x_num/2;
    const int count_y=m_y_num; 
    
    //确定每个显示刻度之间的宽度    
    float spaceX=(float)(width-myleft-myright)/count_x;    
    float spaceY=(float)(height-mybottom-mytop)/count_y;
    float m_x_x=spaceX+7;
       
//x轴
    pDC->MoveTo(int(myleft),int(height-(mybottom+(bottomY)*intervalY)));
    pDC->LineTo(int(width-myright),int(height-(mybottom+(bottomY)*intervalY)));
