echarts中怎样实现部分线段画虚线？-灵析社区

echarts中怎样实现部分线段画虚线？代码如下，目前可设置整体虚线，但不会设置某条线条为虚线。 let charts = { nodes: [ { name: '1', value: [0, 700] }, { name: '2', value: [200, 700] }, { name: '4', value: [300, 700] }, { name: '5', value: [400, 700] }, { name: '9', value: [600, 700] }, { name: '15', value: [900, 700] }, { name: '17', value: [960, 700] }, ], linesData: [ { name: '降水1（10天）', coords: [[20, 700], [190, 700]], type: "dotted" }, { name: '开挖1\n（5天）', coords: [[220, 700], [290, 700]] }, { name: '砂石垫层1\n（5天）', coords: [[320, 700], [390, 700]] }, { name: '混凝土基础1（10天）', coords: [[420, 700], [590, 700]] }, { name: '混钢筋混凝土安装1（15天）', coords: [[620, 700], [890, 700]] }, { name: '土方回填1\n（3天）', coords: [[920, 700], [950, 700]] }, ] } let option = { xAxis: { min: 0, max: 2200, show: false, type: "value", }, yAxis: { min: 0, max: 1000, show: false, type: "value", }, grid: { left: 50, right: 0, bottom: 0, top: 0 }, tooltip: { show: false, axisPointer: { type: "shadow", }, borderColor: "white", backgroundColor: "white", borderWidth: 1, padding: 5, textStyle: { fontSize: 14, color: '#333', }, }, series: [ { type: "graph", coordinateSystem: "cartesian2d", symbol: "circle", symbolSize: [40, 40], // edgeSymbol: ['', 'arrow'], // edgeSymbolSize: [1, 10], lineStyle: { normal: { width: 0, color: 'green', } }, itemStyle: { color: "rgb(194, 194, 194)", }, symbolOffset: [10, 0], force: { edgeLength: 100, repulsion: 150 }, label: { show: true, color: '#333', }, data: charts.nodes }, { type: "lines", polyline: false, coordinateSystem: "cartesian2d", symbol: ['', 'arrow'], symbolSize: 10, label: { show: true, position: "middle", fontSize: 16, color: '#333', formatter: function (args) { }, }, lineStyle: { color: '#65B7E3', width: 2, }, data: charts.linesData, }, ], };  { name: '混钢筋混凝土安装1（15天）', coords: [[620, 700], [890, 700]] }, 比如在上面这行代码中是否可设置参数实现虚线呢？ lineStyle中设置type: "dashed"可实现虚线，
