hello Ignat,
Thanks for your help. I've been following up on your hint and somehow I understand that I may have a design flaw, so I was hoping you could help me review it and define the right approach.
I have a series of groups (field Category) for which I want to evaluate the distribution of the total sum of values(field Values) grouped by path (field Paths) for every category. (The pie slices/Arcs)
I need to be able to configure the color of the pie slices so they can be picked through the color Palette.
But I also need to have a 3rd measure (Field Measure) to be shown in the middle of the pie chart, that depends from the field "Category" independently of "Paths" and "Values". It is usually a % hence I cannot aggregate randomly as sometimes will not be a dynamic DAX measure. (I'm OK forcing it to be though)
Before I was using unable to configure the color palette for the chart slice groups but everything else was working:

}Now after raising the question here, I've been working to build something different that I think would allow me to create selectors for the slices, but I cannot see how I can get the measure for the "Category" field.

Is it possible to group all the independent combinations of category-path in a single colorPalette setting and at the same time have a measure dependent on the category field?
Some help will be REALLY appreciated.
Thanks a lot in advance,
