I am using this example to setup a control layer.


L.control.layers(baseMaps, overlayMaps).addTo(map);

How do I just update overlayMaps with latest markers? In other words, the user may or may-not have the overlayMaps "checked" and I just want to update the markers based on latest data.

Use L.Control.Layers.addOverlay() and L.Control.Layers.removeLayer().
