Labelling point - Visualising Data - CFD

Hi I really hope that is easy solution,

I managed to successfully run CFD case using Butterfly Package thanks to Mostapha to joining our territory.
Please see my case.
As we have finally FREE and OpenSource CFD that runs under Dynamo we need to find a way of labelling points so we can use this in our presentations and verify CFD work.
I tried Labelling points but it does not work. I mean no errors but can not see Lables.

Please help,
