Daily average in Easy Chart

I’m trying to figure out how to create an easy chart with average daily values (8am to 8am) over the last year. I’m not having any luck finding any combination of aggregation mode and duration that gives me that result. Is this something that’s doable with Tag History pens, or is it going to require a SQL query to build the dataset? (I’m still very new to Ignition, this was easy to do in iFix)

Setting sample size to 24 hours didn’t work?
