Hey guys, hitting a bit of a wall here, I'm trying to build a PI Processbook overview page with 8 or so rolling bar graphs showing hourly tonnages for the last 24 hrs for a bunch of different conveyors.

I could not find any way to easily build these bar graphs in processbook so I have been using Datalink in Excel then embedding the Excel plots in Processbook, but that brings about its own series of problems (can't find a way to start it updating by itself). Is there something obvious I'm missing in Processbook? I just need plots showing the range of the totaliser tag for the last 24 hours (starting on the hour).

Anyone had experience or had to do something similar? I get the feeling I'm running around in circles and its probably something obvious. Tongue

Hi,

Unfortunately the ProcBook Trend object hasn't the functionality of the Excel chart object.

What you can do: create a data set with the hourly average (if necessary), trend it using PITrend. Or, if you want to see bars, clue 24 bars together.

Yeah I'm resorting to embedded excel chart objects at the moment, getting them to update regularly has been a bit of a pain.
