折线图 根据数据格式显示不同线条

图示：

 

数据格式代码：

lineChartsData: {
                xData: ['家具', '电器', '数码', '食品', '服装', '医药'],
                yData: [
                    {
                        name: '店铺一',
                        data: [10, 50, 60, 24, 52, 35]
                    },
                    {
                        name: '店铺二',
                        data: [20, 80, 50, 34, 22, 45]
                    }
                ]
            }
