draw again the axes frame

try the following with the pstricks-add, v 2.54

% Shade the area between lines
\begin{psgraph}[axesstyle=frame,ticklinestyle=dotted,xticksize=0 10,%
   yticksize=0 10](0,0)(10,10){1.75in}{1.1in}%
   \readdata{\data}{test.dat}%
   \pscustom[fillstyle=solid,fillcolor=gray]{%
     \psline(0,0)(0,1)      % dummy lines for filling
     \listplot[plotNo=2,plotNoMax=2]{\data}%
     \listplot[plotNo=1,plotNoMax=2,ChangeOrder]{\data}% <----
   }
\end{psgraph}
