TITLE

[Feature] echarts how multiple bar charts show only a single markLine

BODY

What problem does this feature solve?

line diagram, business needs to configure the maximum and minimum values, and then draw on echarts, through the official document the most suitable is the markLine configuration of line, now encounter the following problems:

1. Because it is a multi-line chart, if the markLine is only set in the first item of the series, and the first line is turned off because there is a legend, the markLine will not be displayed
2. If each item of the series is drawn, there will be a performance waste and the markLine will be overlapped

Of course I know this design is reasonable, but I think this business need is also reasonable, is there an alternative here for echarts?

What does the proposed API look like?

I want a global markLine to be able to be configured like title and tooltip

suggestion: 1) precalculate min and max for all series, 2) add a line with no name and no data 3) add min/max marklines to this extra line

建议：1）预先计算所有系列的最小值和最大值，2）添加一条没有名称和数据的行 3）为这个额外的行添加最小值/最大标记线

@helgasoft I know you can do this, but you need to set up the stack, which feels weird, so I mentioned feature issues

@helgasoft I did this the other way around, with stack there was a bar misalignment, I used line, which always felt weird

series: [
  {
    type: 'bar',
    data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  },
  {
    type: 'bar',
    data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  },
  {
    type: 'bar',
    data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  },
  {
    type: 'line',
    markLine: {
      silent: true,
      data: [
        {
          name: 'Max',
          yAxis: 9
        },
        {
          name: 'Min',
          yAxis: 2
        }
      ]
    }
  }
];
