how to add formatter tooltip in echart for multiple values for pie diagram

Question

I am using echart pie diagram but I want to show multiple records in tooltip.

option = {
    tooltip: {
        trigger: 'item',
        formatter: '{a} <br/>{b} : {c} ({d}%), <br/>{name1} : {value1} '
    },
    legend: {
        orient: 'vertical',
        left: 'left',
        data: ['aa', 'bb', 'cc', 'dd', 'ee']
    },
    series: [
        {
            name: 'text name',
            type: 'pie',
            radius: '55%',
            center: ['50%', '60%'],
            data: [
                {value: 335, name: 'aa',value1: 335, name1: 'xx'},
                {value: 310, name: 'bb',value1: 335, name1: 'yy'},
                {value: 234, name: 'cc',value1: 335, name1: 'zz'},
                {value: 135, name: 'dd',value1: 335, name1: 'ww'},
                {value: 1548, name: 'ee',value1: 335, name1: 'vv'}
            ],
        }
    ]
};

I have tried with this formatter: '{a}
{b} : {c} ({d}%),
{e} : {f} ({g}%)' and '<%=name%>:<%= value %><%\n%><%=name1%>:<%= value1%><%\n%><%=name2%>:<%= value2 %>' this link :https://echarts.apache.org/examples/en/editor.html?c=pie-simple

If you want to customize the tooltip then you can use a callback function for formatter property and access all the related data. I have created a demo for you, please let me know if you face any issue.

// 基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById('main'));

option = {
  tooltip: {
    trigger: 'item',
    formatter: function (params) {
      
      return `${params.seriesName}<br />
              ${params.name}: ${params.data.value} (${params.percent}%)<br />
              ${params.data.name1}: ${params.data.value1}`;
    }
  },
  legend: {
    orient: 'vertical',
    left: 'left',
    data: ['aa', 'bb', 'cc', 'dd', 'ee']
  },
  series: [{
    name: 'text name',
    type: 'pie',
    radius: '55%',
    center: ['50%', '60%'],
    data: [{
        value: 335,
        name: 'aa',
        value1: 335,
        name1: 'xx'
      },
      {
        value: 310,
        name: 'bb',
        value1: 335,
        name1: 'yy'
      },
      {
        value: 234,
        name: 'cc',
        value1: 335,
        name1: 'zz'
      },
      {
        value: 135,
        name: 'dd',
        value1: 335,
        name1: 'ww'
      },
      {
        value: 1548,
        name: 'ee',
        value1: 335,
        name1: 'vv'
      }
    ],
  }]
};

// use configuration item and data specified to show chart
myChart.setOption(option);

<script src="https://cdnjs.cloudflare.com/ajax/libs/echarts/3.7.2/echarts.min.js"></script>
<div id="main" style="width: 600px;height:400px;"></div>

This is the best option if you want to add custom types and parametres. Thanks. — Sinan Eldem, Feb 26 '23 at 15:00

We can use Formatter callback inside tooltip, legend, label options in ECharts, and changes their values accordingly. For your convenience, I have created a Nice Pie Chart Using Echats you can follow it.

enter image description here Options Field Code-:

option = {
    tooltip: {
        trigger: 'item',
        // formatter: '{a} <br/>{b} : {c} ({d}%)'
        formatter: function (params) {
          return `
                 <b>${params.data.type}</b></br>
                  ${params.value} : ${params.data.name} <br />`
    }
    },
     legend: {
      
        left: 'right',
        orient: 'vertical',
        right: 10,
        top: 'center',
        bottom: 20,
        textAlign:'center',
        // formatter: function (value) {
        //     return  `${value}`
        //   }
        // data:['80%','90%','20%']
    },
    title : {
        text: 'Total Assets',
        subtext : 'J$200000',
        left: 'center',
        top:'center'
    },
    series: [
        {
            name: 'Dishant',
            type: 'pie',
            radius: ['40%', '70%'],
            label: {
                show: true,
                formatter: function (params) {
                    return `${params.data.type}`
                 }
            },
            emphasis: {
                label: {
                    show: true,
                    fontSize: '16',
                    fontWeight: 'bold'
                }
            },
            labelLine: {
                show: false
            },
            color : 
            [
                '#003F8D', '#42A1D3', '#A1C1E0', '#83A3D3','#29B3C4'
            ],
            data: [
                {value: 1048, name: '70%',type : 'Managed product'},
                {value: 735, name: '80%', type : 'Stocks'},
                {value: 580, name: '90%',type : 'Bonds'},
                {value: 484, name: '100%',type : 'Cambio'},
            ]
        }
    ]
};

You can pass the data you want to the series object and access it from the tooltip callback func at the data key
