For specifying plot statements, the OVERLAYEQUATED layout is similar to the
OVERLAY layout: you can specify one or more 2-D plot statements within the layout
block. However, OVERLAYEQUATED imposes a restriction on the plot axes and
differs from OVERLAY in several ways. With OVERLAYEQUATED:
• Both X and Y axes are always numeric (TYPE=LINEAR). Thus, plot types that have
discrete or binned axes (BOXPLOT, BOXPLOTPARM, BARCHARTPARM,
HISTOGRAM, and HISTOGRAMPARM ) cannot be used within this layout.
• For equal data intervals on both axes, the display distance is the same. For example,
an interval of 2 units on the X axis maps to the same display distance ...
