Adding your own calculator, correct method? #42

Open mistyn8 opened 8 years ago

mistyn8 commented 8 years ago

A little confused about overriding the calculator...

should it be as per the example here http://gmaps-utility-library-dev.googlecode.com/svn/trunk/markerclusterer/examples/simple_example_with_values.html

eg passed in as a option on instantiation.. var markerCluster = new MarkerClusterer(map, markers, {'calculator': average});

or using the markerCluster.setCalculator(function(markers, numStyles) {...});

I couldn't seem to get the example method to work, but assume there might be an overhead setting after instantiation?

Hey! If it's ok to have calculator globally, you can override function like this:

MarkerClusterer.prototype.calculator_ = function(markers, numStyles) {
...

coffeescript:

MarkerClusterer::calculator_ = (markers, numStyles) ->
...
