Hi I was just wondering if anyone has developed a ad-Hoc trend for Edge on vision Cheers Paul ---

Have you tried this one? [Ignition Exchange: Ad Hoc Trend for Vision](https://inductiveautomation.com/exchange/92/overview) ---

Do note that the Ad-hoc trending package expects there to be a database into which setups can be saved. You'd have to replace those parts with local filesystem operations in Edge. ---

Hi sorry for delayed response, not sure how to edit the database for edge historian I don’t think it will work. It also needs a DB for annotation on trend which I would like but this is not available in edge. Any ideas? ---

Use local files instead of databases. Edge doesn't have and doesn't permit database operations. (You will need to re-engineer every part of the adhoc trends that look up options and user settings in the DB.) ---

How would you approach this? Would you set up a database on the edge machine and access that file directly instead of through a database connection in edge? ---

> [@Sean\_LaFleur](#): > > Would you set up a database on the edge machine No, you don't set up a database for use with Edge. You use some other file format (JSON, perhaps) to hold chart settings. That's what I mean by "re-engineer" in my previous comment. If you don't have a programmer who understands this, perhaps you should not use Edge.
