When I’ve selected to show data labels as percentage (instead of number) the colors in the tooltip do not match the graph or the legend. Very annoying. Only thing I think to do as a work around is create a calculated field for the percentage and then display that number which would be a very annoying workaround.
Interesting, I tested this and it seemed to work fine for me! I’d love to reproduce this on my end so I can file a bug, can you share more about your SETUP and STYLE options?
