Stacked Line Chart

Similar to the Stacked Bar Chart, Stacked Line Chart use the 'stack' in series to decide which series should be stacked together.

option = {
  xAxis: {
    data: ['A', 'B', 'C', 'D', 'E']
  },
  yAxis: {},
  series: [
    {
      data: [10, 22, 28, 43, 49],
      type: 'line',
      stack: 'x'
    },
    {
      data: [5, 4, 3, 5, 10],
      type: 'line',
      stack: 'x'
    }
  ]
};

However, without clarification, it is hard for us to judge whether it is a stacked line chart or normal line chart. Therefore, filling color for the area under the line is recommended to indicate for a stacked line chart.

option = {
  xAxis: {
    data: ['A', 'B', 'C', 'D', 'E']
  },
  yAxis: {},
  series: [
    {
      data: [10, 22, 28, 43, 49],
      type: 'line',
      stack: 'x',
      areaStyle: {}
    },
    {
      data: [5, 4, 3, 5, 10],
      type: 'line',
      stack: 'x',
      areaStyle: {}
    }
  ]
};
