问题 I need to sort the data of series from largest to smallest for every series. Sample fiddle series: [{ name: 'John', data: [{ y: 1}, {y: 2}, {y: 3}, {y: 4}, {y: 5 }] }, { name: 'Jane', data: [{ y: 5}, {y: 4}, {y: 3}, {y: 2}, {y: 1 }] }, { name: 'Joe', data: [{ y: 5}, {y: 2}, {y: 3}, {y: 4}, {y: 1 }] }] 回答1: You can use the sort function. It can be applied like that: series.forEach(function(name){ name.data.sort(function (a,b) { if(a.y < b.y) { return 1; } else if (a.y > b.y) { return -1; }
