alex2wong commented on issue #12080: Donut chart with centered dynamic text URL: https://github.com/apache/incubator-echarts/issues/12080#issuecomment-576314424 > @alex2wong I want custom dynamic text at center. sure, the label could be customized by string formatter or callback function based on data ``` label: { normal: { show: false, position: 'center', formatter: function(params) { // callback function if (params.dataIndex === 0) { return params.data[params.dataIndex]; } else { return '' } } }, emphasis: { show: true, formatter: `customized {a}\n {b}: {c}` // string formatter } }, ``` please refer to doc: https://echarts.apache.org/en/option.html#series-pie.label.formatter and try in this demo: https://echarts.apache.org/examples/zh/editor.html?c=pie-doughnut
