Highcharts

问题 I am currently using Angular 7+ with Highcharts API. I integrated Highcharts using the following Official Github Link. There is a callbackFunction in Highcharts which we can use to get the chart instance .

The code for sorting seriesData.forEach(function (name) { if (name.data != undefined) { name.data.sort(function (a, b) { if (a < b) { return -1; } else if (a > b) { return 1; } return 0; }); } }); Here is full my source code JSfiddle https://jsfiddle.net/viethien/hdy2frkv/9/ var seriesData = [{ "name": "(Component)", "data":

问题 I didn't see any solutions matching the exact scenario I was hitting in Highcharts so I'm posting my find here.
