jspdf不能正确采集DIV内容highcharts下载的pdf格式

Question

我想下载HTML中的PDF fprmat的内容，但在我的情况下，我使用highcharts但是当我下载的PDF它不是能捕捉到图表的内容，更能够捕捉到纯文本contents.I已经使用这些额外的插件像addimage，标准字体等，即使它不能print.is有任何其他插件，我需要使用呢，还是需要使用插件的任何highcharts，这里是下面的代码

    $(function () {
    
        var specialElementHandlers = {
            '#editor': function (element,renderer) {
                return true;
            }
        };
     $('#cmd').click(function () {
            var doc = new jsPDF();
            doc.fromHTML(
                $('#container').html(), 15, 15, 
                { 'width': 170, 'elementHandlers': specialElementHandlers }, 
                function(){ doc.save('sample-file.pdf'); }
            );
    
        });  
    });
    Highcharts.chart('container', {
    
        title: {
            text: 'Solar Employment Growth by Sector, 2010-2016'
        },
    
        subtitle: {
            text: 'Source: thesolarfoundation.com'
        },
    
        yAxis: {
            title: {
                text: 'Number of Employees'
            }
        },
        legend: {
            layout: 'vertical',
            align: 'right',
            verticalAlign: 'middle'
        },
    
        plotOptions: {
            series: {
                label: {
                    connectorAllowed: false
                },
                pointStart: 2010
            }
        },
