Steps to Reproduce

好用的例子如下

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [150, 230, 224, 218, 135, 147, 260],
      type: 'bar',
      markLine: {
        data: [{
            name: '平均线',
            // 支持 'average', 'min', 'max'
            type: 'average'
        }]
      }
    }
  ]
};

不好用的例子如下

option = {
  dataset: {
    source: [
      ['score', 'amount', 'product'],
      [89.3, 58212, 'Matcha Latte'],
      [57.1, 78254, 'Milk Tea'],
      [74.4, 41032, 'Cheese Cocoa'],
      [50.1, 12755, 'Cheese Brownie'],
      [89.7, 20145, 'Matcha Cocoa'],
      [68.1, 79146, 'Tea'],
      [19.6, 91852, 'Orange Juice'],
      [10.6, 101852, 'Lemon Juice'],
      [32.7, 20112, 'Walnut Brownie']
    ]
  },
  xAxis: {type: 'category'},
  yAxis: {
    type: 'value'
  },
  series: [
    {
      type: 'bar',
      encode: {
        x: 'product',
        y: 'amount'
      },
      markLine: {
        data: [{
            name: '平均线',
            type: 'average'
        }]
      }
    }
  ]
};

[Bug] When using dataset, markline will report an error

duplicate of #21300 This "ordinalMeta" bug 🐛 seems related to column positions inside dataset.source. It is triggered when the number of columns is >=3 AND the X-axis column position is >=3 : Demo.
