Dojox DataChart与Legend

Question

我想使用JSON文件与Legend制作Pie DataChart 我的js代码看起来像这样

    var store  = new dojo.data.ItemFileWriteStore(
    { url:dojo.moduleUrl("dojox.charting", "file.json") 
});
makeObjects = function(){
    var chart1 = new dojox.charting.DataChart("test11111111", {
        type: dojox.charting.plot2d.Pie, // <-- chart type. Can be used Pie
        scroll:false,
        stretchToFit:true
    });
    var c = dojo.connect(chart1, "onData", function(){
        dojo.disconnect(c);
        new dojox.charting.widget.Legend({chart:chart1}, "legendPie");
    });
chart1.setStore(store2, {legend:"*"}, "ss_series");
chart1.render();

JSON文件就像这样

{ "items": [
    { "ss_series":[10126, 9803, 15965, 17290, 15667, 17762], 
      "legend":["Rome", "Paris", "Madrid", "Berlin", "London", "Dublin"]}
]}

问题在于Legend还显示了馅饼的百分比而不是图例值 有人能帮我吗？ 感谢

Answer 1

如何将数据重新格式化为：

"ss_series": [{y: 10126, legend: "Rome"}, {y: 9803, legend: "Paris"} , ... ] 

这应该可以解决问题吗？
