I have no idea how to modify the labels.
Is anyone able to help out with this request?
Are you saying that the data you have has two different categories, or are you saying that you are seeing 2 different names for the same set of data?
In either case, you could fix this in the base data, or you could do this via beastmode. If you only have 2 distinct data sources and just want to rename it, this is what I would use:
when `Label` = 'Old name 1' then 'New Name 1'
when `Label` = 'Old name 2' then 'New Name 2'
The "error" field will let you know if anything falls outside of those two labels.
Hope this helps!
