在高图表中，我有一个数组如下，但是，如果我尝试通过返回数组的最大值来设置图表的极端值，则会显示 NaN 错误。

我试图获得最大值的代码是：
MinAssortmentValue = Math.min.apply(Math, chartlength);
这是更新的jsFiddle链接： http://jsfiddle.net/sarav4gs/jbmk9tb1/3/
任何人都可以帮我修复它吗？提前感谢！！
...参考我的这个评论 - 如何处理复杂数据结构的列表 - 草图方法可能看起来像那样，即使我仍然不知道您要比较和/或提取的图表项目的对象属性是什么......
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);
将刚刚提供的代码粘贴到您提供的小提琴的控制台中确实会导致以下输出：
minMaxValues : Object {
minValue: 1458000000000,
maxValue: 1485820800000,
minValueItemIndex: 9,
maxValueItemIndex: 14
}
minAssortmentValue, maxAssortmentValue : 1458000000000 1485820800000
