I need help finding this

At one time I had a chartplotter, I thought it was my Garmin 276-C, that had a barometric pressure graph or line that ran across the top of the page like a temperature graph.

I called Garmin and the tech said it wasn't a Garmin.

It was a cool feature and I would like to find out what unit had this feature

I do remember having to select how it was displayed, millibars, etc.

Any help will be appreciated.
