<font face="Myriad Pro">Hi Hamed,<br>
<br>
here an example file to experiment around a little and to be modified
to your special needs:<br>
<br>
<br>
\documentclass[12pt,a4paper]{article}<br>
\usepackage{geometry}<br>
\geometry{tmargin=1cm,bmargin=1cm}<br>
\usepackage{pst-plot}<br>
\begin{document}<br>
<br>
Without clipping<br>
<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\psplot{0.5}{4}{2 x div}<br>
\end{pspicture}<br>
\hfill<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psframe*[linecolor=lightgray](4,4)<br>
\psaxes(4,4)<br>
\psplot{0.5}{4}{2 x div}<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\end{pspicture}<br>
<br>
Without and with \verb|\psclip|<br>
<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\pscustom[linecolor=red]{%<br>
\psplot{0.5}{4}{2 x div}<br>
\lineto(4,4)}<br>
\pscustom[linecolor=blue]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\lineto(0,0)}<br>
\end{pspicture}<br>
\hfill<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\begin{psclip}{%<br>
\pscustom[linecolor=red]{%<br>
\psplot{0.5}{4}{2 x div}<br>
\lineto(4,4)}<br>
\pscustom[linecolor=blue]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\lineto(0,0)%<br>
}%<br>
}<br>
\psframe*[linecolor=lightgray](4,4)<br>
\end{psclip}%<br>
\end{pspicture}<br>
<br>
The next two versions are wrong,<br>
but this is important to understand why... (both with \verb|\psclip|<br>
<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\begin{psclip}{\pscustom[linecolor=red]{%<br>
\psplot{0.5}{4}{2 x div}}<br>
\pscustom[linecolor=blue]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}}}<br>
\psframe*[linecolor=lightgray](4,4)<br>
\end{psclip}%<br>
\end{pspicture}<br>
\hfill<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\begin{psclip}{\pscustom[linecolor=red]{%<br>
\psplot{0.5}{4}{2 x div}}<br>
\pscustom[linecolor=blue]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}}}<br>
\psframe*[linecolor=lightgray](4,4)<br>
\end{psclip}%<br>
\psline[linecolor=green](0,3)(3,0)<br>
\end{pspicture}<br>
<br>
<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\begin{psclip}{\pscustom[linecolor=red]{%<br>
\psplot{0.5}{4}{2 x div}<br>
\lineto(4,4)}<br>
\pscustom[linecolor=blue]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\lineto(0,0)}}<br>
\psframe*[linecolor=lightgray](4,4)<br>
\end{psclip}%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\psplot{0.5}{4}{2 x div}<br>
\end{pspicture}<br>
\hfill<br>
\begin{pspicture}(-0.5,-1)(4,4)<br>
\psaxes(4,4)<br>
\begin{psclip}{\pscustom[linestyle=none]{%<br>
\psplot{0.5}{4}{2 x div}<br>
\lineto(4,4)}<br>
\pscustom[linestyle=none]{%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\lineto(0,0)}}<br>
\psframe*[linecolor=lightgray](4,4)<br>
\end{psclip}%<br>
\psplot{0}{3}{3 x x mul 3 div sub}<br>
\psplot{0.5}{4}{2 x div}<br>
\end{pspicture}<br>
