How do I perform a distinct count operation in a text widget?

Question

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.

Any ideas?

I'm having the opposite problem. For me the Count() function seems to return distinct values on a text field, when I want it to return the total number features with that field populated. So I want what you got and you want what I got! I wonder why this is?

Thanks Lasya, but this doesn't do Distinct Count.

You can use the COUNT operator under the Statistics tab or Expressions tab in Dynamic content window. 
COUNT({text_field})
