Highcharts重复代码

Question

我使用Highcharts创建了2个饼图，但我复制了代码。

如何才能拥有一个基于代码的代码 - 在不同的json文件中调用。

var chart1 = {
                chart: {
                    renderTo: 'container1'

                },

                        return '<b>' + this.point.name + '</b>: ' + this.y.toFixed(2) + ' % / £' + this.point.mv;
