Highcharts多列平均值

Question

我是html / javascript开发的新手，并希望使用类似于此https://www.highcharts.com/demo/column-basic的高图表图表，但每个城市的年平均值显示在折线图中（即相同的图表重复12次） 。我已经使用SQL来生成平均值，因此不需要代码，但在创建图表时我似乎无法正确地获得格式。

任何建议都将受到赞赏。

谢谢

code

Highcharts.chart('content-daily-delivery-status', {

    chart: {
        type: 'column',
        width: width
