Herbert,

   I'll need to play with your code to understand how to use it well.

   Yesterday's figure is what prompted me to write (code modified from what
worked in previous figures; probably not optimum):

\documentclass[12pt,letterpaper]{article}
\usepackage{pstricks-add,graphicx}
\usepackage[margin=1cm]{geometry}
\newsavebox\PSTBox

\begin{document}

   \psset{framesep=2mm,arrowscale=1.75}

   %\begin{pspicture}[showgrid](-1.0,-0.25)(15,15)
   \begin{pspicture}(-1.0,-0.25)(15,15)
     \pscircle(5,5){4.7cm}
     \pscircle(10.5,5){4.0cm}
     \psline[linewidth=3pt](5,5)(10.5,5)
     \psline[linewidth=3pt](5,5.25)(5,4.75)
     \psline[linewidth=3pt](10.5,5.25)(10.5,4.75)
     \psline{->}(5,5)(2.18,1.18)
     \psline{->}(10.5,5)(12.68,1.6)
     \psline{->}(8.3,8.3)(8.3,5)
     \rput(5,5.6){2006}
     \rput(10.5,5.6){2005}
     \rput(8.3,4.5){2004}
     \rput(2.6,3.7){Circle with}
     \rput(2.6,3.2){radius 47}
     \rput(12.75,3.7){Circle with}
     \rput(12.75,3.2){radius 40}
   \end{pspicture}
\end{document}

   It is the terminal coordinates of those last 3 \psline functions that I
fit by trial-and-error. I need to think how the use of tangents will help me
on this. And, I should have included this code in my original message.

Thanks,

Rich
