Trend: Vertical gridlines
Plots such as the pad trends, could benefit from grid lines to help quantify the changes over time. The horizontal axis has decent grid definition between the grey and the black, but the lack of vertical axis makes it hard to compare day to day comparisons.
In PI Vision 2020, trend symbol enhancements were made including the ability to change the trend gridlines to vertical/horizontal lines or plain.
For additional information on PI Vision 2020, please see the release announcement here:
Im Trendfenster sollte die möglichkeit zum einblenden eines Gitters/Raster gegeben sein.

The lack of vertical grid lines is actually a show-stopper for using PI Vision in some departments over here....
