饼图怎么支持排序 #6358

可以给 stackY 加配置参数：

import { Chart } from '@antv/g2';

const data = [
  { item: '事例五', count: 9, percent: 0.09 },
  { item: '事例一', count: 40, percent: 0.4 },
  { item: '事例二', count: 21, percent: 0.21 },
  { item: '事例三', count: 17, percent: 0.17 },
  { item: '事例四', count: 13, percent: 0.13 },

];

const chart = new Chart({
  container: 'container',
  autoFit: true,
});

chart.coordinate({ type: 'theta', outerRadius: 0.8 });

chart
  .interval()
  .data(data)
  .transform({ type: 'stackY', orderBy:'value', reverse:true }) // 这里
  .encode('y', 'percent')
  .encode('color', 'item')
  .legend('color', { position: 'bottom', layout: { justifyContent: 'center' } })
  .label({
    position: 'outside',
    text: (data) => `${data.item}: ${data.percent * 100}%`,
  })
  .tooltip((data) => ({
    name: data.item,
    value: `${data.percent * 100}%`,
  }));

chart.render();
