ECharts漏斗图（多级）：如何展示数据流程和转化率

// 获取容器var container = document.getElementById('chartContainer1');// 创建ECharts实例var myChart = echarts.init(container);// 配置参数var option = {    title: {        text: '多级漏斗图',        subtext: '数据流程和转化率'    },    tooltip: {        trigger: 'item',        formatter: "{a} <br>{b} : {c}%"    },    toolbox: {        show: true,        feature: {            magicType: {                type: ['funnel', 'pyramid']            },            restore: {},            saveAsImage: {}        }    },    legend: {        data: ['阶段1', '阶段2', '阶段3']    },    calculable: true,    series: [        {            name: '漏斗图',            type: 'funnel',            left: '10%',            width: '80%',            label: {                normal: {                    formatter: '{b} : {c}%'                }            },            data: [                {value: 60, name: '阶段1'},                {value: 40, name: '阶段2'},                {value: 20, name: '阶段3'}            ]        }    ]};// 渲染图表myChart.setOption(option);
