Question

我有以下代码。在给定的一天，它显示平均等待时间和最长等待时间（以秒为单位）。情节线目前给出了这两个值的平均值。我想要的是，平均值只考虑平均时间，因此对于用户选择的特定时期，该行将显示该时段的平均值

var seriesOptionsChatChart = [],
seriesCounterChatChart = 0,
namesChatChart = ['ChatChartAVG','ChatChartMAX'];

function createChartChatChart() {

    Highcharts.stockChart('chart27', {

        rangeSelector: {

更改if(serie.name !== 'Navigator') {以专注于我想要的系列

Highcharts addPlotLine用于一组值
