I'd like to ask what is the purpose of custom colors in stacked bar charts if you are not able to display a legend of what each of those colors represent? How have you worked around this usability issue?
Hi Clark, it's an anoying thing for sure. What I've seen in this cases vary on how 'open mind' your customer is. For example you can try to use the tree map object without dimension, 1 as metric and use the same custom color expression. That way you will keep the assosiation and you can simulate a legend/filter.
