Can you be a bit more specific?

Are you trying to use the fitMapMaxZoom property?

Or do you want ClusterMarker to create cluster markers on all map zoom levels - even if fully zoomed in?

If you can then please post a link to your map - makes it much easier to answer a question

.

Martin.

I can't show the map yet I'm afraid for legal reasons.

No I'm not using the fitMapMaxZoom property.

I just want to restrict the level that the map will zoom in to. This is because of privacy issues I dont want to give the impression the marker is pointing at someone's street.

Does that make sense?

Hi again.

Well you could PM me a link to your map if you like and i'll keep it to myself.

Otherwise there's various ways to limit a map's maximum zoom level.

You could use some code such as this to set every map type's maximum zoom level to whatever you desire.
(The code assumes that your map is named 'map').



var map_types = map.getMapTypes();

for (var i=0; i<map_types.length; i++){

 map_types[i].getMaximumResolution = function() {return 15;};

}

Executing that code after you have created and initialised your map will make each map type's maximum zoom level 15 - you can experiment with different zoom levels to achieve what you want.

Other ways would be to catch the 'zoomend' event and check the map's current zoom level.
If the map has zoomed in too much then zoom back out to an acceptable level.
This would achieve the same as the above code but is not so elegant and may be a performance hit on your map.

Post again if i still haven't answered your question.

Martin.
