By custom stastics I mean the ones I can add myself(those graphs that show up).
To recreate(doesn't matter if local or distrbiuted)
Create two scenarios (I had 1 generator, 1 soap runner, and one log table in each).
Run load test and you will get the statistics. Don't need to run for a long time.
Now, run the same test but unlink one of the scenarios. You will notice that you get no statistics or just the custom statistics.
If you did add custom statistics many of them will not work(such as min/max) response time, although the blank chart will show up.
