After carefully configuring the analysis template to map to an AF Attribute I was delighted to see the expected results. These particular AF Attributes are not being written to a pi tag. In PI System Explorer I can right click and trend the values. In PI ProcessBook I can also trend the values of this 'Analysis' data reference AF Attribute. However, in PI Vision I simply get "No Data". I will skip the numerous measures I have taken from rebuilding the index in PI Web API, testing other display elements, and trolling the search engines for answers to simply ask - why? Do non pi point attributes not display values in PI Vision?
