Ad hoc trending is a feature that is in development for the upcoming release of PI Vision 2019. This feature will support selecting data from displays to add to an ad hoc trending workspace for analyzing data and investigating issues on the fly.
Thank you for your comments! Our plan for the ad-hoc trending feature would allow selection of data items from various displays and clicking an 'add to trend' button to add these data items to a trend in another view. We would make it easy to toggle between the view of the trend and the display but you would not be able to see the ad-hoc trend and display at the same time.
I'm interested to hear why you find it useful to see the trend and the display at the same time and whether the functionality I described would be a sufficient alternative.
The PI Vision 2017 R2 release included enhancements to symbols to better support excluded attributes. If attributes are flagged as “excluded” in an AF hierarchy, values will not be displayed in the table symbol and asset comparison table in PI Vision. Other symbols will display “N/A” for excluded attributes.
We will consider expanding on this behavior to address missing attributes and to completely excluded or missing attributes in non-table symbols in a future release.
Thanks for your feedback! Symbol grouping was implemented in PI Vision 2017 so you should be able to use it as soon as you upgrade to the latest version.
A format painter is still under consideration for a future release.
It's currently possible to change the asset template used. The asset template field is implemented as a typeahead, so the dropdown is showing you all of the templates that match what is currently entered - could you try clearing out the current template and selecting a different template?
Thanks for your comments! This is quite helpful!
To answer your question - yes, PI Vision 4.x will handle PI Point renames as well as element or attribute renames.
Thanks for your comments! We're making changes in the next version of PI Vision (PI Vision 4.x) that will handle updates to attribute and element names automatically. Do you see additional value in having this sort of tool if attribute name changes no longer affect display configuration?
Symbols are created with the same initial configuration every time they are added to a display. For example, a table symbol is always created with the min and max columns enabled. Users should be able to define the default configuration options for each symbol.
