I am trying to allow the user to select which tags are fed to system.tag.querytaghistory. Is there some way to use the tag browse tree or row selector to do this? Ideally, I would display a subset of tags to the user and let them highlight or check which ones get used in the report.
If you are using Ignition 7.7 then you can use the system.tag.browseTags function. You can read about it in the Ignition User Manual.
If you are using Ignition 7.6 then you can install the IA Labs Scripting module and use the system.tag.browseTags function.
