Hi,
Try:
var myClusterStyleMap = new OpenLayers.StyleMap({
'default': new OpenLayers.Style({
externalGraphic: 'http://openlayers.org/dev/img/marker.png',
graphicWith: 21,
graphicHeight: 25,
label: '${count}',
labelOutlineColor: "#aaaaaa",
labelOutlineWidth: 2
}, {
context: {
count: function(feature) {
if (feature.cluster) { // is `.cluster` the array of
clustered features
return feature.cluster.length; // or
feature.attributes.count, is the same
} else { // is not clustered
return ''; // no label
}
}
}
})
});
kml_layer = new OpenLayers.Layer.Vector("KML", {
projection: map.displayProjection,
strategies: [new OpenLayers.Strategy.Fixed(),
new OpenLayers.Strategy.CenteredCluster({threshold: 2 // to
display single cluster as feature
})
],
styleMap: myClusterStyleMap,
protocol: new OpenLayers.Protocol.HTTP({
url: filename,
format: new OpenLayers.Format.KML({
extractStyles: true,
extractAttributes: true,
maxDepth: 3
})
})
});
Now I have put everything you need, including `new` I neglected ;-) ...and
now is tested.
NOTE: When extracting uses "extractStyles: true" features ignore the layer
styles, so is not necessary '${myGrafic}' if uses "threshold: 2".
