聚合点设置minPoints: 1未生效，点为1时没有显示聚合图层 #2789
Description
问题描述
聚合点对于单个点时没生效，虽然设置了minPoints: 1，但是还是没有形成聚合涂层
版本：
"@antv/l7": "^2.20.14",
"@antv/l7-maps": "^2.20.14",
示例代码如下：
`import { PointLayer, Scene, Source } from '@antv/l7';
import { GaodeMap } from '@antv/l7-maps';
const scene = new Scene({
id: 'map',
map: new GaodeMap({
center: [120.19382669582967, 30.258134],
style: 'dark',
zoom: 3,
}),
});
scene.on('loaded', () => {
let testData = [
{
name: "Plug'nRoll",
owner: "Plug'nRoll",
lat: 46.913439,
lng: 9.781794,
},
];
const dataSource = new Source(testData, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat',
},
cluster: true,
clusterOption: {
radius: 40,
minPoints: 1,
},
});
// 3. 图层样式
const devPointLayer = new PointLayer({ zIndex: 1 })
.source(dataSource)
.shape('circle')
.size('point_count', [10, 15, 20, 25])
.color('#67C23A')
.style({ opacity: 1 });
// 4. 文字图层
const devPointLayerText = new PointLayer({ zIndex: 3 })
.source(this.dataSource)
.shape('point_count', 'text')
.size(12)
.color('#fff')
.style({ opacity: 1 });
this.scene.addLayer(devPointLayer);
this.scene.addLayer(devPointLayerText);
});`
