Trend: Show data item descriptions
Be able to view the tag/attribute descriptions on the bottom of the trend the same way that you are able to in ProcessBook. For those of us with large DB, it is very important to have this functionality.
In PI Vision 2020, we added labeling options to the trend symbol (and other symbols) to show element/tag/attribute name, tag/attribute description, or custom text. This allows you to configure the trend legend to show data item descriptions.
For more information, see the PI Vision 2020 release announcement here:
If your feedback request includes the ability to change the positioning of the legend in the trend symbol, please subscribe to the feedback item here:
i would have it show underneath the tag name and give the option to show the tag name, description or both.

I copied and modified the Trend Symbol to put my own legend on it.
We use this everywhere now. It was also important to see the real tag names and not the AF alias

Again, it's difficult to understand why OSISoft present their flagship product with such deficient standard items. It should have been policy to, at very least, provide an item that was at least as good as the ProcessBook symbol it replaced. ProcessBook allows inclusion of any combination of value, units, name, descriptor: this should have been the starting point, not something that needs to be asked for......

This shall be a standard PI function.
Currently PI show the tag path, tag and description on the pop up opened when you put the cursor aver the TAG in the ASSET list display (left side of the window).
However the same is NOT shown when you put the cursor over the tag in the trend display.
Both of these comments are good. Being able to search descriptions would be very useful when someone has a general idea of what they need but might not know the equipment (tag) number.
Description when searching would also be very valuable.

That indeed should be a must-have feature to have. The need of having the description in the trend is bigger when you don't have still an AF hierarchy and you are using PI tags in the trends. Most of the times PI tag names are not very friendly and it is hard for people to guess what data they are visualizing.
