Wow, talk about Major Brain Fart... I got locked on the Data Log tab under the aquaero and didn't see the primary one I needed. I'll ask later what the aquaero Data Log is used for.
OK, I set up a data set, made the chart the way I wanted, saved the chart and am able to pick it up on the Display Page.
Only thing is, when I closed the edit function of the display page to set it on the desktop, the data log graph is not there.
I know it must be something simple, but am not able to determine my error.
Edit, by the by, thank you both very much for your help.
