visualization of data frequency

Hi, @Gergely.

I would create a set called S_AllePostleitzahlen with attributes ‘Index’ set to “PLZ” and ‘Parameter’ set to “Pe_PLZ”: 

Then I would populate this set with all possible PLZ:

Remark: you can also populate it easily with every PLZ that has frequency >= 1 using your original table Hilfsbeduerftige(i), that I named P_YourOriginalTable(i,) using a procedure:

After that, I would create a parameter P_PostleitzahlHaufigkeit(PLZ) that counts the PLZ frequency:

and then you can use this parameter (P_PostleitzahlHaufigkeit(PLZ)) directly on the barchart object.

Idk if it’s the best approach but it works. Hope it helps!
