Beta testers now have the option to add value labels to column graphs in DevResults. The option is shown in the display panel.
Note: This feature is currently only available to beta testers. Anyone can opt-in to view features in beta testing on the user profile. Once we've ensured that the feature works well, it will be made available to all users.
Values appear horizontally if there's enough space for them, and vertically if there's not.
In the future we might explore options to add labels for targets and other visualization types, but it's a complex challenge to ensure proper spacing for an infinite number of text sizes and positions.
