Build trend with multiple traces based on a display data (for instance, from a table). PI Vision user should be able to select multiple items on the table and then trend them on a single ad-hoc trend to compare. The ad-hoc trend should appear in a pop-up window (which you can move) in the same browser tab and the user should be able to switch between the main screen and the ah-hoc trend window to drag and drop more attributes from tables and value symbols on the screen. It's very important to see both ad-hoc trend and the main display simultaneously.
