折线图tooltip中在生图echarts category配置项内容和展示

当需要折线图上某一个点的数据（如100 是由50 20 30组成）的组成方式，就可以使用这种方法，通过获取当前的X Y坐标，把当前的数据添加到饼图

      option = {
    title: {
        text: '折线图tooltip中在生图'
    },
    tooltip: {
        padding: 3,
        backgroundColor: '#222',
        borderColor: '#777',
        borderWidth: 1,
        formatter: function(obj) {
            var value = obj.value;
            var yindex = obj.dataIndex;
            var xindex = obj.seriesIndex;
            setTimeout(function() {
                stockPieManagement("ebox");
                pieChartsFn(yindex, xindex);
            }, 100)
            return '<div style="width:200px;height:200px;" id="ebox" class="ebox"></div>'

        }
