It's normal because the cluster strategy replace your features with points.
The main goal for a cluster strategy is to regroup features that are close and make the map the more "readable". And with the cluster strategy you can change the radius of the clustered points like that : // Définit les styles des features var style = new OpenLayers.Style({ fillColor: "#ee9900", fillOpacity: 0.8, hoverFillColor: "#ee9900", hoverFillOpacity: 0.8, strokeColor: "#ee9900", strokeOpacity: 0.8, strokeWidth: 1, strokeLinecap: "round", strokeDashstyle: "solid", hoverStrokeColor: "blue", hoverStrokeOpacity: 1, hoverStrokeWidth: 0.2, pointRadius: "${radius}", hoverPointRadius: 1, hoverPointUnit: "%", pointerEvents: "visiblePainted", cursor: "inherit" }, { context: { radius: function(feature) { return Math.min(feature.attributes.count, 9) + 4; } }); view = new OpenLayers.Layer.Vector("View", { // strategies: [fixedStrategy, clusterStrategy, lineStringclusterStrategy], strategies: [fixedStrategy, clusterStrategy], protocol: myprotocol, styleMap: new OpenLayers.StyleMap({ "default": style, "select": { fillColor: "#8aeeef", strokeColor: "#32a8a9" } }) }); Hope it will help you ;) -- View this message in context: http://www.nabble.com/Polygon-Cluster-tp20189385p20190295.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
