I have approx 15 different Geomaps, each showing between 10 - 40 devices associated to the group showed on that map. Geomaps show me the location of each device, which is great. I wanted to add a donut showing the exact number of devices, so the operator openthe map and quickly see "this client has 21 machines online". But all I could find was donuts displaying the whole number of sensors, not the number of devices. Any way I can have the map display that ?
