环形图中心指标能否设置选中时展示？-灵析社区

可以参考如下options option = { tooltip: { trigger: 'item' }, legend: { top: '5%', left: 'center' }, series: [ { name: 'Access From', selectedMode: 'single', type: 'pie', radius: ['40%', '70%'], avoidLabelOverlap: false, label: { show: false, position: 'center' }, emphasis: { label: { show: true, fontSize: 40, fontWeight: 'bold', formatter:'{c}' } }, labelLine: { show: false }, data: [ { value: 1048, name: 'Search Engine' }, { value: 735, name: 'Direct' }, { value: 580, name: 'Email' }, { value: 484, name: 'Union Ads' }, { value: 300, name: 'Video Ads' } ] } ] };
