Pen Layout

You can are 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.
