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. A Graph with Labeled Axes Full Graph.
