How to have line labels on both sides of a Y-axis?

I don't think there is inbuilt support for that. Best I can think of right now is to use the regular endLabel for the end of the series and a markPoint with symbolSize 0 on top of the first datapoint as start label.

Example:

const dataset = [[150, 230, 224, 218, 135, 147, 260], [230, 160, 70, 135, 147, 140, 110], [135, 147, 260, 340, 290, 110, 90]];
const entity = ['Mangolia', 'Mitzerland','Torsica'];

const seriesList = [];
for (const index in dataset) {
  const row = dataset[index];
  seriesList.push({
    type: 'line',
    data: row,
    endLabel: {
      show: true,
      formatter: () => 'end label = ' + row[row.length - 1]
    },
    markPoint: {
      symbolSize: 0,
      label: {position: 'left'},
      data: [{coord: [0, row[0]], value: entity[index]}]
    }
  });
}

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: seriesList
};

Start label

markPoint: {
  symbolSize: 0,
  label: {
    position: 'left', 
    formatter: (params)=> `${params.value} = ${params.data.coord[1]}`
  },
  data: [{coord: [0, row[0]], value: entity[index]}]
}

End label

endLabel: {
  show: true,
  formatter: (params) => 'end label = ' + row[row.length - 1]
}

You can also use endLabel to show label at end.

Also, to show label at start you can use Markpoint with formatter to show series name and start value.
