One-line summary [问题简述]

Dataset in Echarts 4 does not work properly with line series that have the stack prop.

Version & Environment [版本及环境]

  • ECharts version [ECharts 版本]: 4.0.2
  • Browser version [浏览器类型和版本]: chrome 65
  • OS Version [操作系统类型和版本]: arch linux

Expected behaviour [期望结果]

Like the option below, with 4 series 'a', 'b', 'c', 'd' that have the same stack prop, should add up by order, always be 'a' < 'b' < 'c' < 'd'.
But the result is strange, the order is wrong, and lines even cross each other.

ECharts option [ECharts配置项]

option = {
  legend: {},
  tooltip: {
    trigger: 'axis',
  },
  dataset: {
    source: [
      ['order', '1', '2', '3', '4', '5', '6'],
      ['a', 41.1, 30.4, 65.1, 53.3, 83.8, 98.7],
      ['b', 86.5, 92.1, 85.7, 83.1, 73.4, 55.1],
      ['c', 24.1, 67.2, 79.5, 86.4, 65.2, 82.5],
      ['d', 55.2, 67.1, 69.2, 72.4, 53.9, 39.1],
    ],
  },
  xAxis: { type: 'category' },
  yAxis: { gridIndex: 0 },
  series: [
    { type: 'line', stack: 'sameStack', smooth: true, seriesLayoutBy: 'row' },
    { type: 'line', stack: 'sameStack', smooth: true, seriesLayoutBy: 'row' },
    { type: 'line', stack: 'sameStack', smooth: true, seriesLayoutBy: 'row' },
    { type: 'line', stack: 'sameStack', smooth: true, seriesLayoutBy: 'row' },

  ],
};
