Show data sources linked to a symbol
Currently a symbol (except some standard symbols) do not have any way to show which data items are linked to a symbol. If you need to be sure, you either need to remove and recreate the symbol, or build support for that in your custom symbol, or look into the display definition in SQL.
I would like some way do look into which data items are used in a symbol, so that users can validate the configuration of the symbol.
While we appreciate the interest the community has for this suggestion, we have decided to decline this item in favor of other high priority work the product needs. Thank you for your feedback, and please continue sharing suggestions for how we can improve PI Vision for you!
