When running a test I noticed that the UDT tags appear in the easy chart tag browser. The non UDT tags do not appear in the tag browser even though history is enabled. However, you can drag and drop the non UDT tags onto the easy chart ok.

I am not seeing this behavior, can you tell me a little more about it? What version of Ignition are you using? All tags with history enabled should show in the list.

Was this working prior to the beta release?
