XY-pic Reference Manual

This document summarises the capabilities of the XY-pic package for typesetting graphs and diagrams in TEX. For a general introduction as well as availability information and conditions refer to the User’s Guide [14]. A characteristic of XY-pic is that it is built around a kernel drawing language which is a concise notation for general graphics, e.g., A B (/).*-+, j j j j j j j j j G ' 55 was drawn by the XY-pic kernel code \xy (3,0)*{A} ; (20,6)*+{B}*\cir{} **\dir{-} ? *_!/3pt/\dir{)} *_!/7pt/\dir{:} ?>* \dir{>} \endxy It is an object-oriented graphic language in the most literal sense: ‘objects’ in the picture have ‘methods’ describing how they typeset, stretch, etc. However, the syntax is rather terse. Particular applications make use of extensions that enhance the graphic capabilities of the kernel to handle such diagrams as Round gfed `abc _^]\ XYZ[ Square
