In my Excel file, I have a column labeled "Comment" that I would like represented in yEd as a tooltip. I understand that the Description field in yEd displays as a tooltip, but I don't see how to map imported data from Excel to the Description field. I did have the Comment field mapped to Tooltip in the Properties Mapper, but this didn't do anything that I could figure out. Am I missing something? Is it possible to do what I am trying to do? Thanks.
