Dear folks,


Please consider the following code.

\documentclass[pstricks,border=12pt,12pt]{standalone}
\usepackage{pst-plot,pst-text}
\psset{unit=4cm}

\def\f{sqrt(x)}
\def\g{x}

\begin{document}
\multido{\r=-1.0+0.1}{18}{%
\begin{pspicture}[algebraic,plotpoints=200](-1,-1)(2.25,2.25)
\psaxes{->}(0,0)(-1,-1)(2,2)[$x$,0][$y$,90]%
\pstextpath[r](0,.1){\psplot[linecolor=blue]{-.5}{1.5}{\g}}{\textcolor{blue}{$g(x)= x$}}%
\pstextpath[c](\r,.1){\psplot[linecolor=red]{0}{1.5}{\f}}{\textcolor{red}{$f(x)=\sqrt x$}}%
\end{pspicture}}
\end{document}

There is a small red horizontal line as shown in this figure http://i.stack.imgur.com/mVTOu.gif. Is it a bug?


Thank you in advance.


best regards,


I am who I say I am
