I want to control the access of specific graphic in PI Vision. There are two groups, the "A" group users must not be able to watch the graphics of the "B" group. Now there are security control in PI AF and PI Archive but all the users can se all the graphics although see "No Data" in the current value of the the graphic whit out permision. ¿Exist some way to restrict the visualitation of the all graphic to some users (hidden)? I mean, justo only able to see their especific graphics.
