$(function () {
    $(‘#container‘).highcharts({

        xAxis: {
            categories: [‘Jan‘, ‘Feb‘, ‘Mar‘, ‘Apr‘, ‘May‘, ‘Jun‘, ‘Jul‘, ‘Aug‘, ‘Sep‘, ‘Oct‘, ‘Nov‘, ‘Dec‘]
        },
        
        tooltip: {
            shared: true, //是否共享提示，也就是X一样的所有点都显示出来
            useHTML: true, //是否使用HTML编辑提示信息
            headerFormat: ‘<small>{point.key}</small><table>‘,
            pointFormat: ‘<tr><td style="color: {series.color}">{series.name}: </td>‘ +
            ‘<td style="text-align: right"><b>{point.y}</b></td></tr>‘,
            footerFormat: ‘</table>‘,
            valueDecimals: 2 //数据值保留小数位数
        },
    
        series: [{
