Django+highcharts画饼状图问题

  • django
  • javascript

view代码如下

listz.append({"name": str(key.name),"value":int(total)})
return render(request, "cartogram6.html", {'Z': listz})

highcharts用的是官网的模板，是这样的

<!DOCTYPE HTML>
<html>
    <head>
        <meta charset="utf-8"><link rel="icon" href="https://jscdn.com.cn/highcharts/images/favicon.ico">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <style>
            /* css 代码  */
        </style>
        <script src="https://img.highcharts.com.cn/highcharts/highcharts.js"></script>
        <script src="https://img.highcharts.com.cn/highcharts/modules/exporting.js"></script>
        <script src="https://img.hcharts.cn/highcharts-plugins/highcharts-zh_CN.js"></script>
    </head>
    <body>
        <div id="container" style="min-width:400px;height:400px"></div>
        <script>
            // JS 代码

            Highcharts.chart('container', {
        chart: {
                plotBackgroundColor: null,
                plotBorderWidth: null,
                plotShadow: false,
                type: 'pie'
        },
        title: {
                text: '出库到各个客户的商品数量占比'
        },
        tooltip: {
                pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        },
        plotOptions: {
                pie: {
                        allowPointSelect: true,
                        cursor: 'pointer',
                        dataLabels: {
                                enabled: true,
                                format: '<b>{point.name}</b>: {point.percentage:.1f} %',
                                style: {
                                        color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
                                }
                        }
                }
        },

        series: [{
                name: 'Brands',
                colorByPoint: true,
                data:{{ Z|safe }}

        }]
});
        </script>
    </body>
</html>
