Color Picker selection not persisting when apply setting for "ALL" is selected .

Hi  Daniel29195 ,

To put it simply, the color you choose for All does get applied to all series, but the color picker doesn't show or remember that selection. So, while it seems like it's not saved, it actually is, this is just a limitation of the UI, not an issue with your custom visual.

Because this is a UI limitation and everything is functioning correctly, it would be a good idea to share this in the Ideas Forum mentioned below for visibility and possible improvements in future updates.

Hi  Daniel29195  ,

In custom visuals, formatting properties are defined in the capabilities model. A property can be configured as an enumeration (dropdown) or can be bound to a field/measure for conditional formatting (fx), and the formatting pane renders these based on how the property is defined.

Because of this, the typical approach is to use either a dropdown for fixed options (such as blink or pulse) or a field/measure to drive the behavior dynamically, depending on the requirement.
