Echarts - Default value tooltip formatter for pie chart

Question

Does somebody know what is the default tooltip.formatter value for pie charts ? Currently I am using version 5.4.2, and for previous versions it was like this {a} <br/>{b}: {c} ({d}%), but now you can see that they added an icon near category name, and I want to catch it.

option = {
  //...
  tooltip: {
    trigger: 'item'
  },
  //...
}

I want to get something similar to this formatter: '{b.icon} {b}: {c} ({d}%)'. Another thing I observed is that the number in the default formatter is bold, but in mine is not.

Example

Any help will be useful, thanks!

Answer 1

You can get the icon via params.marker. The default formatter is like this.

tooltip: {
  trigger: 'item',
  formatter(params) {
    return `${params.seriesName}<br>${params.marker}${params.name}<span style="float: right; margin-left: 20px"><b>${params.value}</b> (${params.percent}%)</span>`;
  }
},
