In the graphics, below, we see the way that the data is represented when the column sizes are different:-
The left-side graphic shows three dots (...) if there is more than one value represented in the corresponding week. If we manually make the columns wider, then the data is represented correctly (right-sided graphic).
Working with Tableau 10, does this version offer auto-fit column capability? Or is there a workaround solution?
I'm curious what behavior you see when you put it in a layout container on a dashboard with "Automatic Fit". You'll also want to "Clear Manual Sizing" on the view. It probably won't be perfect, but should be a little better for you.
