I am trying to create a venn diagram and found an old post (How to get dynamic Venn Diagram in Qlikview | Qlik Community) that was very helpful indeed. But I have found something that does not seem to me correct. When I assume a condition in which customer 1 and customer 2 have common things, customer 2 and customer 3 have common things and customer 3 and customer 1 have common things but there is nothing in common among all three customers, then I find the chart still gives intersection for three customers but actually there is no value for common items in all three customers. I have selected the values in attached qvd to show you the issue. Could you please have a look and share your views.
