Improve Digital State visualization in PI Vision

The digital state visualization PI Vision needs to be improved to allow the observation of the value with the time. The visualization of digital state values in PI Vision with trends has the following limitations: • It is not possible to have trend stacking: https://feedback.osisoft.com/forums/320517-pi-vision/suggestions/13734045-trend-stacking • It is not possible to customize ranges for the traces outside the digital state values: https://feedback.osisoft.com/forums/320517-pi-vision/suggestions/43035336-trend-with-digital-state-show-only-digital-state What we need is a modern visualization symbol that allows stack trend traces and properly shows the digital state variation with time. When hovering with the pointer we would like to display all values for that timestamp in both digital states and quantities. We basically need the exact type of view as offered in OCS to be included as a PI Vision symbol.
