arcgis api for javascript 4.12 vue 点聚合(1)
使用的插件是FlareClusterLayer(插件链接)
插件案例,(部分代码,完整的请自行下载)
注意: 引入插件需要使用绝对地址,使用script，不要加 type=“text/javascript”
主要代码
function initLayer(data) {
// 默认样式
var defaultSym = {
type: "simple-marker",
size: 6,
color: "#FF0000",
outline: null
};
var renderer = new ClassBreaksRenderer({
defaultSymbol: defaultSym
});
renderer.field = "clusterCount";
var smSymbol = {
type: "simple-marker",
color: [255, 204, 102, 0.8],
size: 22,
outline: {
color: [221, 159, 34, 0.8]
}
}
var mdSymbol = {
type: "simple-marker",
size: 24,
outline: {
color: [82, 163, 204, 0.8]
},
color: [102, 204, 255, 0.8]
};
var lgSymbol = {
type: "simple-marker",
size: 28,
outline: {
color: [41, 163, 41, 0.8]
},
color: [51, 204, 51, 0.8]
};
var xlSymbol = {
type: "simple-marker",
size: 32,
outline: {
color: [200, 52, 59, 0.8]
},
color: [250, 65, 74, 0.8]
};
renderer.addClassBreakInfo(0, 190, smSymbol);
renderer.addClassBreakInfo(200, 1500, mdSymbol);
renderer.addClassBreakInfo(1510, 5000, lgSymbol);
renderer.addClassBreakInfo(5001, Infinity, xlSymbol);
var areaRenderer;
var options = {
id: "flare-cluster-layer",
clusterRenderer: renderer,
spatialReference: new SpatialReference({
"wkid": 4326
}),
subTypeFlareProperty: "deviceName",
singleFlareTooltipProperty: "deviceId",
displaySubTypeFlares: true,
maxSingleFlareCount: 8,
clusterRatio: 75,
data: data
}
var clusterLayer = new fcl.FlareClusterLayer(options);
map.add(clusterLayer);
}
vue下使用
效果
首先在public/index.html引入插件, 重点提示
主要的代码,通过控制clusterRatio 范围大小, 来控制点聚合区域, data为点集合数据
