Ok. :/ Thanks again.
In case anyone else has an idea, here is the problem again, in pictures:
Here's what happens if I want to convert an ABC dimension to a measure (doesn't work, just counts every value as 1).
If I "convert to numbers" first, then turn the dimension into a measure, it works and gives me a proper graph! (see below)
However, then I have all these duplicate columns that I don't want. Too many columns; makes the analysis confusing.
I want to get rid of the original (ABC) columns and just keep the ones where the values are recognized as numbers (123).
Thanks in advance for any advice on how to do this.
