@zcg8633 可以试试加上 autoBatch: true，不过不能保证会有很大的提升，自定义系列因为灵活性所以很难针对大数据做优化
```ts
return {
type: 'sector',
autoBatch: true,
shape: {
cx: params.coordSys.cx,
cy: params.coordSys.cy,
r0: coord[2] - size[0] / 2,
r: coord[2] + size[0] / 2,
startAngle: -(coord[3] + size[1] / 2),
endAngle: -(coord[3] - size[1] / 2)
},
style: api.style({
fill: api.visual('color')
})
};
```
