All GTL graphs are specified
within layout blocks that enable you to control the graph display
features, including the display of the axes for the plots within the
layout. For example, the LAYOUT OVERLAY statement has XAXISOPTS= and
YAXISOPTS= options that enable you to specify axis features for the
plots within the layout.
The following sections
explain how the axis features are determined in a layout. The sections
also discuss the issues that you must consider when setting the axis
type or adjusting the appearance of the axis display.
