[pstricks] pst-plot

[Patrice MÉGRET]

Dear Herbert,

I have data located between (30,1583.9) and (100,1584.0) and I have trouble with pst-plot.

My first idea was to use

\begin{psgraph}[mathLabel=false,labelFontSize=\small,Dy=0.1, Oy=1593.0,Ox=30,Dx=10]{->}(30,1593)(110,1584){8cm}{5cm}
\end{psgraph}
but I get this error message:

! Dimension too large.
<recently read> \pst at yunit

l.40 ...x=10]{->}(30,1583.0)(110,1584.0){8cm}{5cm}

By the way,
\begin{psgraph}[mathLabel=false,labelFontSize=\small,Dy=0.1,Ox=30,Dx=10]{->}(30,0)(110,1){8cm}{5cm}
\end{psgraph}
perfectly works but here ymin=0 and ymax=1 .


To overcome this problem, I used \pstScalePoints(1,1000){}{1584 sub} to scale y-values by 1000 and to locate my data between (30,0) and (110,800).
By letting  Dy=0.1,dy=100,Oy=1584.0,Ox=30,Dx=10 in psgraph I can re-create "by hand" the correct axes and  the picture is correct.

Now, I would like to add a frame and extend the x and y ticks to draw the grid.
So I just add   xticksize=0 800, yticksize=0 80 to psgraph and I still get the error:

! Dimension too large.
<recently read> \@psunit

l.57 ..., yticksize=0 80](30,0)(110,800){8cm}{5cm}


Below the %%%%%%%%%%%%%%%, you will find the code with the three tests.

Have any idea of the problem and how I can solve it?



Best regards,
Patrice
