Specifies the positioning of the plot and its associated annotation (i.e., anything that can be specified with the PLOT command). The difference between !P.Region and !P.Position is that !P.Region provides a margin around the plot to accommodate plot annotation. It is called by specifying !P.Region’s maximum and minimum values in normalized coordinates:

!P.Region = [Xmin, Ymin, Xmax, Ymax]

For example, to position a plot with its associated annotation in the center of the screen, type:

!P.Region = [0.2, 0.2, 0.8, 0.8]
