Ignition Perspective Power Chart

The Chart doesn't save what user selected. it will back to what we selected in designer when navigate back to the Power Chart View.

Understand that we need store the pens in somewhere. Any idea how to implement it? store or session custom or somewhere?

Found the Ad-Hoc Trend in Exchange but it needs to use MongoDB. Any solution to solve it by ignition itself?

Thank you very much.

Looking at the Ad Hoc Trends resource on the Exchange, it supports more multiple SQL flavors, not just MongoDB.

If you don't want to use a database at all, you could probably throw together something simple that saves the config in a session prop on an onShutdown event and loads the config on an onStartup event. This would not persist per user across logins though - for that you'll need to use a database.
