I've recently started working on a project involving google maps with a custom html file, which has several hundred markers which I must label by ID. Because the built in marker label only works for one character, I added a custom label to display the marker number underneath. The problem at the moment is that I have the markers set to hide at a certain zoom level, but the labels will not disappear, and instead just cluster together. Does anyone know a way to bind the visibility settings? The only way that I've been able to make the label disappear is to set the visibility to hidden within the CSS style script.
