[pstricks] \psplot ans \parametricplot

[Herbert Voss]

Hello all,

the new version of pstricks-add defines a new optional
argument for \psplot and \parametricplot.

\psplot[settings]{x0}{x1}[PS args]{ y(x) }
\parametricplot[settings]{t0}{t1}[PS args]{ x(t) y(t) }

PS args is passed directly to PostScript which makes
the use of \pstVerb superfluous, e.g.

\documentclass{article}
\usepackage{pstricks-add}
\begin{document}

\psset{xAxisLabel=t, yAxisLabel=U}
\begin{psgraph}{->}(0,0)(0,-1.5)(11,1.5){12cm}{8cm}
\makeatletter
\psplot[plotpoints=20,linecolor=red,linewidth=2pt]{0}{10}
  [ /yMax 1 def /T0 1 def /T1 T0 def ]% <=== this is new !!!!
  { x T1 gt {
      T1 yMax \tx at ScreenCoor
      2 copy 4 2 roll L neg L
      /yMax yMax neg def /T1 T1 T0 add def } if yMax }
  \end{psgraph}

\end{document}
