            tooltip: {
                formatter: function() {
                    return ''+
                        this.x +': '+ this.y +' mm';
                }

            plotOptions: {
                column: {
                    pointPadding: 0.2,
                    borderWidth: 0
                }
            },
                series: {{ data }} // i change
        });
    });

});

Answer 1

替换

series: {% data %}

与

series: {{ data }}

{{ variable }} 当你想使用从 python 脚本传递到模板的变量时使用。
