使用 echart 实现一个折线图内线段的多种不同形式

通过不同形式的线段代表过去、当下、未来（预测）

效果图

代码如下

option = {
  title: {
    text: 'Stacked Line'
  },
  tooltip: {
    trigger: 'axis'
  },
  legend: {
    data: ['Email', 'Union Ads', 'Video Ads']
  },
  grid: {
    left: '3%',
    right: '4%',
    bottom: '3%',
    containLabel: true
  },
  toolbox: {
    feature: {
      saveAsImage: {}
    }
  },
  xAxis: {
    type: 'category',
    boundaryGap: false,
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun',"","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""]
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      name: 'Email',
      type: 'line',
      stack: 'Total',
      data: [872, 950, 1034, 1123, 925, 804, 932, 1109, 1083, 941, 1056, 857, 882, 1136, 938, 899, 862, 1149, 1135, 1108, 1005, 1001, 1049, 1124, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null
]
    },
    {
      name: 'Union Ads',
      type: 'line',
      stack: 'Total',
      data: [null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, 0, 1000, 1200, 1039, 861, 1016, 850, null, null, null, null, null, null, null, null
]
    },
    {
      name: 'Video Ads',
      type: 'line',
      stack: 'Total',
      data: [null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, 0, 1073, 842, 1087, 948, 1091, 1182, 998, 963],
      lineStyle:{
        type: 'dashed'
      }
    }
  ]
};
