Legend on a Feflow charts!

Hi! :)
I would like to insert a legend in the graph of "Local concentration" on Feflow (after the simulation) but "Chart properties" don't provice me any legend. I talk about the Local concentration chart related to the observation point, and not the legend of active view. How can I do it?
Thank you very much! :)

The recent implementation shows you the labels of the histories. A legend is not supported. Accordingly, you need to visualize the histories externally.
