If I add a chart
chose chart from a related table
then set the Chart and Label field
Click cog wheel to config and the Chart field always go back to the first Field in the list.
Is this a bug or something? Why does it keep going back?
Open back up
Also the help says I can pick a table or a popup for related records but how? I see no option for this - it always shows me a table no matter what.
With a one-to-many relationship, choose to display the related data in the pop-up window or in a table.
Submitted a case to Esri, they already have it logged as BUG-000104430 which was originally logged on 4/10/2017. Let's hope for a fix in the December update!
Though not the exact same use case, if you can, give the Dashboard Theme with the Infographic widget a try - their best attempt at charts and graphics yet.
