Hello there, is it possible to A) easily put all the data from different columns on the same level in a chart B) create a 2 levels chart with a hierarchy ? And if not, do you plan to support any of the 2 at some point? Here's an example of what I'm trying to achieve. Don't mind the actual data, I took it from google image, slight difference in our case: all data of the outward level are different across the columns (ie: we would have something like values A, B, C in the inner part, and A1, A2, A3, B1, B2, C1, C2, C3 in the outer)

Hi Bastien, GoodData doesn’t support multi-level circular charts (like sunburst or radial trees). I am not aware of any plans to implement this. However, I will gladly submit a product feedback on your behalf so our product team can consider this in future developments.

Hello, and thanks for the answer. We already did something with drilling but sadly it is not enough. There's another way that could actually help us: being able to aggregate/flatten multiple columns into one attribute. I understand that the usecase is a bit specific, granted we could manipulate the data before giving them to the LDM, but let's assume we can't. So, would it be possible, either through the LDM, or via MAQL, to create an attribute that isn't a 1-1 to a column? Basically something that take the first non-empty value from multiple columns would be enough
