Duplicate Clusters

[ldrrp]

Notice i only have 4 markers, and the clusters have two groups of 4. I added a debug console log to count the amount of markers created, at each zoom level only 9 are created in this image total for both zoom levels.

My guess is that you have some event handler where every time you zoom/pan, you instantiate a new instance of MarkerClusterer. So that's why your clusters are so close together - because there are actually two MarkerClusterer overlays on top of each other.

What you need to do is to:

• Ensure only one instance of MarkerClusterer is instantiated per map, and
• Clear the markers (e.g. using clearMarkers()) from the map before redrawing them
