如何處理複雜數據結構的列表

Question

在高圖表中我有一個數組如下， 但是，如果我嘗試通過返回數組的最高值來設置圖表的極值，它將顯示NaN錯誤。

function aoDashboardData() { 
var data = [ 

    {  type: "",

我試圖獲得最大價值的代碼是：

MinAssortmentValue = Math.min.apply(Math, chartlength); 

這裏是更新的jsfiddle鏈接：http://jsfiddle.net/sarav4gs/jbmk9tb1/3/

誰能幫我解決這個問題？提前致謝！！

......引用我的這個評論 - How to process a list of complex data structures - 草圖方法可能看起來像這樣，儘管我仍然不確定要比較和/或提取的圖表項目的對象屬性是什麼...

var 
    chart = $('#ao-projectssummry-chart').highcharts(), 

    minMaxValues = chart.series.reduce(function (collector, item, idx/*, list*/) { 
     var 
      dataMin = item.dataMin, 
      dataMax = item.dataMax, 
      minValue = Math.min(collector.minValue, dataMin), 
      maxValue = Math.max(collector.maxValue, dataMax); 

     if (minValue == dataMin) { 
      collector.minValue = dataMin; 
      collector.minValueItemIndex = idx; 
     } 
     if (maxValue == dataMax) { 
      collector.maxValue = dataMax; 
      collector.maxValueItemIndex = idx; 
     } 
     return collector; 

    }, { 
     minValue: Number.POSITIVE_INFINITY, 
     maxValue: Number.NEGATIVE_INFINITY, 
     minValueItemIndex: -1, 
     maxValueItemIndex: -1 
    }), 

    minAssortmentValue = minMaxValues.minValue, 
    maxAssortmentValue = minMaxValues.maxValue; 

console.log("minMaxValues : ", minMaxValues); 
console.log("minAssortmentValue, maxAssortmentValue : ", minAssortmentValue, maxAssortmentValue); 

剪斷粘貼到你所提供的小提琴確實會導致以下輸出的控制檯只提供代碼：

minMaxValues : Object { 
    minValue: 1458000000000, 
    maxValue: 1485820800000, 
    minValueItemIndex: 9, 
    maxValueItemIndex: 14 
} 
minAssortmentValue, maxAssortmentValue : 1458000000000 1485820800000
