dojo/dojox蜘蛛圖的JSON格式

Question

我拼命地嘗試使用json數據來填充我的dojo蜘蛛圖。

首先：我需要先將我的商店（從ItemFileReadStore檢索到）先傳遞給dojox.charting.DataSeries，然後才能將其用於我的蜘蛛圖？

那麼，json需要怎樣的樣子？

這是我剛試過的方式：

var data = {"identifier":"id","items":[ 
        {"id": "1", "data": {"GDP": 2,"area": 6,"population": 2000,"inflation": 15,"growth": 12}}, 
        {"id": "2", "data": {"GDP": 6,"area": 15,"population": 500,"inflation": 5,"growth": 6}}, 
        {"id": "3", "data": {"GDP": 10,"area": 10,"population": 800,"inflation": 2,"growth": 18}} 
        ] 
      }; 
var fileStore = new dojo.data.ItemFileWriteStore({data: data}); 
var store1 = new dojox.charting.DataSeries(fileStore, {query: {id:"1"}}, "data"); 
var store2 = new dojox.charting.DataSeries(fileStore, {query: {id:"2"}}, "data"); 
var store3 = new dojox.charting.DataSeries(fileStore, {query: {id:"3"}}, "data"); 
chart1.addSeries("USA", store1, { fill: "green" }); 
chart1.addSeries("Japan", store2, { fill: "yellow" }); 
chart1.addSeries("Korean", store3, { fill: "orange" }); 
chart1.render(); 

任何想法？

Answer 1

好的，我不能做dojo itemFileReadStore ...不知道爲什麼它不工作。

我通過數據做道場xhr.get請求和引用所接收的數據來解決該問題[I]：

chart.addSeries("<name>", data[0], { fill: "<color>" });
