Externally updated RRD file - how to assoc data source with graph ?

I followed the instructions above and successfully created the data source for the external rrd file - I can see the data in Data Source Info Mode:
filename /cacti/rra/SP1SP2ArpCk.rrd
rrd_version 0003
step 300
last_update 1718737625 [2024-06-18 15:07:05]
arpdiff GAUGE 600 0 NaN 1 125 0

Graph/Data Source Creation Method is set to Advanced.

However after much searching I don't see how to add the data source to a graph. When I click on the plus sign to add a graph item none/nothing is listed in the drop down list.

Any advice greatly appreciated, we have quite a few graphs from the 0.8.8h version that were created using external scripts running in cron that would be difficult to modify.

Thank you.

Should anyone else face this issue, this turned out (as suspected) to be something simple.

You have to assign your data source to a device & assign your new graph to that device. Then the data source(s) will show up in the drop down when you add items to the graph.
