It is not clear from the documentation about how to use the markline when Y-axis is of category type.

What is expected?

I tried using using bellow code but it produced a horizontal line

markLine: { data: [ {name: 'start', xAxis: 2000, yAxis: '0'}, {name: 'end', xAxis: 2000, yAxis: '1'}, ]

What is actually happening?

Vertical line from xAxis value 2000

You can simply do it like:

markLine: {
   data: [ { name: 'xxxx', xAxis: 2000 } ]
}

Notice that in this case you don’t need two value to specify start point and end point.

markLine data should be 2d, Try

markLine: {
            data: [   [
              {name: 'start', xAxis: 2000, yAxis: 0},
              {name: 'end', xAxis: 2000, yAxis: 1},
            ]   ]
          }

But in your case, there is no ‘0’ in yAxis categories. So the markLine wont appear.
