Javascript勾画曲线图(二)

Javascript勾画曲线图(二)

3.自己用到的一个common.js
//取精度
function getPoint(num, l) {
    return (Math.round(num*Math.pow(10, l))/Math.pow(10, l));
}

//浮点除法
function accDiv(arg1,arg2){
    var t1=0,t2=0,r1,r2;
    try{t1=arg1.toString().split(".")[1].length}catch(e){}
    try{t2=arg2.toString().split(".")[1].length}catch(e){}
    with(Math){
        r1=Number(arg1.toString().replace(".",""))
        r2=Number(arg2.toString().replace(".",""))
        return (r1/r2)*pow(10,t2-t1);
    }
}

//浮点乘法
function accMul(arg1,arg2)
{
    var m=0,s1=arg1.toString(),s2=arg2.toString();
    try{m+=s1.split(".")[1].length}catch(e){}
    try{m+=s2.split(".")[1].length}catch(e){}
    return Number(s1.replace(".",""))*Number(s2.replace(".",""))/Math.pow(10,m)
}

//浮点加法
function accAdd(arg1,arg2){
    var r1,r2,m;
    try{r1=arg1.toString().split(".")[1].length}catch(e){r1=0}
    try{r2=arg2.toString().split(".")[1].length}catch(e){r2=0}
    m=Math.pow(10,Math.max(r1,r2))
    return (arg1*m+arg2*m)/m
}

4.没有改动的CSS文件vmlcurve.css
v\:* { behavior: url(#default#VML);} o\:* { behavior: url(#default#VML);}
body {
margin:0px;
padding:0px;
font-size:12px;
text-align:left
}

font-weight:bold;
font-size:12px;
}

.pRed {

}

/*横坐标轴样式*/
.pMonth {
