Please see attached image: is it possible to get the summary from the different colored charts on the top?
Yes, I think you can achieve this
Step 1: Position the dimension in such a way that you have Group at the start. You can either do it in custom view of NUX or in module directly.
Step 2: While publishing the graph make it stacked and not clustered. You should be able to see the summary values on top of the column
Not totally following you on the first point, and regarding the second one I already have it as stacked. Can you please see new attachment to this message? This is how I would want the end result to look like. Maybe this is not possible since I found a thread about this on the Idea Exchange forum section:
@johan.marketoft hello, did you get the problem solved? in classic UX, how to get Total on top of column? I had the same problem, the sorting doesn't work. Thanks
