Can you try using the DATE function: DATE ([Your Date Field])
I had seen that approach in a previous tutorial and couldn't figure out how to get there, because every time I accessed format I had a very limited set of options.
But I did more poking and found it! For others: Don't make any changes to the dimension, just drag the dimension over to rows and from there, right click on the pill and choose "format." (Change it from continuous to discrete if necessary.) Now you should see more options. I was also able to change the "Year" selection to "Day" (the one that's displayed as May 8th, 2015) and the date appears as DD/MM/YY.
So thank you, that helps immensely!
A follow-up though: Is there a way to change how the header is titled? I know I can use aliases if I'm using Measure Names and Measure Values, and I can't figure out how to make that work here because I'm not showing quantitative data.
I'd like to remove "Date of" from the header to make it easier to read:
That's exactly it! Thank you so much!
Any idea why the integer format requires adding 2 before the date turns out right?
