CenterStage Object Class: Axes
Subclass of: Arrows
The arrow class provides an easy means of generating coordinate axes
of various lengths and styles. You specify the number of axes using
the standard Axes directive.
In addition to the standard directives, the Axes class has the
following directives:
Length len
Length {xlen ylen zlen ...}
The Length directive tells how far from the origin the axes
will extend. If only a single number is given, this is used
as the length for all the axes. If more than one is given,
then each axis is scaled independently by the given amount.
Positive
If present, this directive indicates that only the positive
axes should be shown. If not present, both positive and
negative axes are shown.
The Axes class also allows the ArrowHead, ArrowScale, and ArrowMaxLen
directives of the Arrow class.
