I'm migrating a Dashboard over to ExB. I have an indicator that dynamically counts the number of species seen in a feature layer of plant observations.
In Dashboard, I'd add an Indicator widget with a Count statistic on the text attribute species, clicking the "Distinct" slider. This counts the distinct species in the feature layer.
I do not see a way to accomplish this in ExB. I've looked at the Dynamic functions, but they are numeric in nature.
