Problem: I was
able to display the multiples time in a single row, but as tooltip it is
duplicating the values
Feeder (Table across)
used:
IF first()==0 THEN
STR(min([Start
Timestamp]))ELSE
PREVIOUS_VALUE("") + ", " + STR(min([Start Timestamp]))
END
Date tooltip (Table across) used:
IF FIRST()==0 THEN
LOOKUP([Feeder],LAST())END
