Comments:

Used only as part of a custom widget, created from scratch.

If a history window is already open, PkTrend adds its PtObj to the existing window, otherwise it opens a new history window and adds its PtObj to the new window.

PkTrend adds all of the fields in PtObj that are supported by AnalogDataSource, DigitalDataSource, or NotesDataSource to the history window. It also adds numerous related notes tags:

1. The preconfigured system-wide notes tag.

2. All of the notes tags that have a Area field that matches PtObj's Area field.

3. All of the notes tags in all of the groups that contain PtObj.

Example:

((DisableTools || True(TrendPopupDisable)) ? Invalid : Self)\PkTrend(Left, Bottom, Right, Top, \Root, TRUE);
