径向布局的D3不同最大值

Question

我必须像http://www.brightpointinc.com/download/radial-progress-source-code/这样实现D3布局。有人可以告诉我如何为每个圆圈指定不同的最大值？ 示例：我希望第一个圆圈在值200而不是100处完成，第二个圆圈在值400处完成。 我想出了如何全局更改最大值，但不知道如何为每个圆圈更改它......

JSFiddle：https://jsfiddle.net/2o14pnxh/1/

这是每个圆圈的最大值设置为200的代码（当值达到200时，第一个进度条将完成）：

function radialProgress(parent) {
    var _data=null,
        _duration= 1000,
        _selection,
        _margin = {top:0, right:0, bottom:30, left:0},
        __width = 300,
        __height = 300,
        _diameter = 150,
        _label="",
        _fontSize=10;


var _mouseClick;

var _value= 0,
    _minValue = 0,
    _maxValue = 200;

var  _currentArc= 0, _currentArc2= 0, _currentValue=0;

var _arc = d3.svg.arc()
    .startAngle(0 * (Math.PI/180)); //just radians

var _arc2 = d3.svg.arc()
    .startAngle(0 * (Math.PI/180))
    .endAngle(0); //just radians


_selection=d3.select(parent);


function component() {

    _selection.each(function (data) {

        // Select the svg element, if it exists.
        var svg = d3.select(this).selectAll("svg").data([data]);

        var enter = svg.enter().append("svg").attr("class","radial-svg").append("g");

        measure();

        svg.attr("width", __width)
            .attr("height", __height);


        var background = enter.append("g").attr("class","component")
            .attr("cursor","pointer")
            .on("click",onMouseClick);


        _arc.endAngle(360 * (Math.PI/180))

        background.append("rect")
            .attr("class","background")
            .attr("width", _width)
            .attr("height", _height);

        background.append("path")
            .attr("transform", "translate(" + _width/2 + "," + _width/2 + ")")
            .attr("d", _arc);

            .attr("class", "label")
            .attr("transform", "translate(" + _width/2 + "," + (_width + _fontSize) + ")")
            .text(_label);
       var g = svg.select("g")
            .attr("transform", "translate(" + _margin.left + "," + _margin.top + ")");


        _arc.endAngle(_currentArc);
        enter.append("g").attr("class", "arcs");
        var path = svg.select(".arcs").selectAll(".arc").data(data);
        path.enter().append("path")
            .attr("class","arc")
            .attr("transform", "translate(" + _width/2 + "," + _width/2 + ")")
            .attr("d", _arc);

        //Another path in case we exceed 100%
        var path2 = svg.select(".arcs").selectAll(".arc2").data(data);
        path2.enter().append("path")
            .attr("class","arc2")
            .attr("transform", "translate(" + _width/2 + "," + _width/2 + ")")
            .attr("d", _arc2);


        enter.append("g").attr("class", "labels");
        var label = svg.select(".labels").selectAll(".label").data(data);
        label.enter().append("text")
            .attr("class","label")
            .attr("y",_width/2+_fontSize/3)
            .attr("x",_width/2)
            .attr("cursor","pointer")
            .attr("width",_width)
            // .attr("x",(3*_fontSize/2))
            .text(function (d) { return Math.round((_value-_minValue)/(_maxValue-_minValue)*100) + "%" })
            .style("font-size",_fontSize+"px")
            .on("click",onMouseClick);
