[pstricks] Empty space in figure due to \FP statements

[Juergen Rose]

I use in the file circles_1.tex the following code:

\begin{figure}[ht!]
  \begin{centering}
    \fbox{
      \input{circles_3_1.tex}
    }
    \caption{An array of circles}
    \label{fig:circles_3}
  \end{centering}
\end{figure}

At the begin of circles_3_1.tex there are several \FP statements in
front of a pspicture:

\FPset\radiusZd{0.9}
\FPmul\diameter\radiusZd{2}
\FPset\xCee{\radiusZd}
...
\FPmul\radiusZdq\radiusZd{0.25}
\begin{pspicture}[](\xpsmin,\ypsmin)(\xpsmax,\ypsmax)
  \psaxes[]{->}(0,0)(\xmin,-\radiusZdh)(\xmax,\ymax)
...
  \rput(\xgzl,\ygzl){$g_2$}
\end{pspicture}


In the resulting circles_1.pdf there is a lot of empty space at the left
side of the figure. If I split circles_3_1.tex in circles_3_data.tex and
circles_3_2.tex, where circles_3_data.tex contains the \FP statements
and circles_3_2.tex contains the pspicture and include both files in
circles_2.tex:

\input{circles_3_data.tex}
\begin{figure}[ht!]
  \begin{centering}
    \fbox{
      \input{circles_3_2.tex}
    }
    \caption{An array of circles}
\label{fig:circles_3}
  \end{centering}
\end{figure}

the figure looks as expected. It looks if the FP statements in circles_3_1.tex are 
responsible for the right shift of pspicture to right side in circles_1.pdf. 
I would like to have only one input file for one figure but also to avoid this right shift.

Is there any way?
