通過在dc.js中比較另外兩個維度中的數據來維度中的數據總和

我被卡住了，需要通過使用由其他兩個維度索引的數據找到一個維度的數據總和。通過在dc.js中比較另外兩個維度中的數據來維度中的數據總和

例子：

"mode_device","method","discount","time","first_time","paid","p_id","p_sku" 
"Desktop","EBS",,"1344887090","1344887090","1079","8786","PPLB03571285" 
"Desktop","MOBIKWIK-WALLET","89","1474371140","1474371140","591","99068","PPLB009DCBBFREE" 
"AndroidApp","COD","97","1474371149","1438844849","647","72321","PPLB034601" 
"Desktop","JUSPAY","60","1474371158","1474371158","398","92389","PPLB713SQ306" 
"AndroidApp","COD","190","1474371247","1448993680","1261","72685","PLB0029regenerist3" 
"Desktop","JUSPAY","90","1474371346","1474371346","599","86728","PPLB66719804817" 
"Desktop","DEBITCARD","60","1474371366","1465733603","398","92389","PPLB713SQ306" 
"AndroidApp","COD","0","1474371404","1474371404","577","106032","PPLB0335PA0990NM" 
"Desktop","COD","43","1474371404","1468956726","356","13221","PPLB039605"

在這裏，我們比較mode_device和method，我們必須從支付返回數據的總和。

例子： AndroidApp和COD可以重複幾次可以說數據有類似

"Android","COD","234" 
"Android","Ebs","234" 
"Ios","COD","234" 
"Ios","COD","234" 
"Android","COD","234"

我們必須使用dc.js圖表返回像

Android-COD:468 
Android-Ebs:234 
Ios-COD:468

。

我不清楚你的問題你想如何繪製這些數據 - 它會是一個條形圖，條形圖上標有兩個字段嗎？

但是，如果你想既mode_device和method聚集，你可以簡單地創建一個使用這兩個值在其主要維度：

var modeMethodDimension = cf.dimension(function(d) { return [d.mode_device, d.method].join('-'); }); 
var modeMethodGroup = modeMethodDimension.group(function(d) { return +d.paid; });

現在組應具有鍵值對像

[{key: 'Android-COD', value: 468}, {key: 'Android-Ebs', value: 234}, ...]

如果你把它放到dc.barChart這些鍵將是條的名稱。
