Pie legends

Solution

  • You want to display value instead percentages? If yes then this is a little work that need to do because by default legend component don't know about another dimensions of you data. Try to start with this code:

    var option = {
  //...
  legend: {
    formatter: name => {
      var series = myChart.getOption().series[0];
      var value = series.data.filter(row => row.name === name)[0].value
      return name + '    ' + value;
    },
  }
}


      var myChart = echarts.init(document.getElementById('main'));
  var option = {
    tooltip: {
        trigger: 'item',
        formatter: '{a} <br/>{b}: {c} ({d}%)'
    },
    legend: {
        orient: 'vertical',
        left: 10,
        data: ['Category1', 'Category2', 'Category3', 'Category4', 'Category5'],
        formatter: (name) => {
	        var series = myChart.getOption().series[0];
      		var value = series.data.filter(row => row.name === name)[0].value;
      		return name + '    ' + value;
        },
    },
    series: [
        {
            name: 'Series',
            type: 'pie',
            label: { show: false },
            labelLine: { show: false },
            data: [
                {value: 335,  name: 'Category1'},
                {value: 310,  name: 'Category2'},
                {value: 234,  name: 'Category3'},
                {value: 135,  name: 'Category4'},
                {value: 1548, name: 'Category5'}
            ]
        }
    ]
};


myChart.setOption(option);
