eintr: Printed Axes

 
 15.3 Need for Printed Axes
 ==========================
 
 A graph needs printed axes, so you can orient yourself.  For a do-once
 project, it may be reasonable to draw the axes by hand using Emacs’s
 Picture mode; but a graph drawing function may be used more than once.
 
    For this reason, I have written enhancements to the basic
 ‘print-graph-body’ function that automatically print labels for the
 horizontal and vertical axes.  Since the label printing functions do not
 contain much new material, I have placed their description in an
 appendix.  SeeA Graph with Labeled Axes Full Graph.
