Pen Layout

You can display pens in the Process Analyst by stacking or overlaying.

• In stacked mode, a user-specified amount of vertical real-estate is allocated to the pen, and with this, stacked pens are laid out under each other on the pane, starting from the top of the pane under the date/time axis, like this:

  

  Here, three pens (one analog and two digital) are stacked under each other. Stacking applies to every type of pens.

• In unstacked mode, pens are drawn on top of each other. The order in which the pens were added to the pane governs the drawing order: the last pen added is the topmost pen drawn. When a pen is selected, it is brought to the front of any other pens displayed

  

  Here, two analog pens are overlaid. You can also overlay digital and alarm pens.

You can have any mix of stacked and unstacked pens on a pane.
