Final thoughts...<BR>
The best solution is definitively to put dy to 1cm, as Herbert said. I like this way of working, because it will ensure a good coherence throughout the document. The distance between the labels will remain the same.<BR>
<BR>
However, Dy must then be equal to [(Oy size) / (real size * scaling)]<BR>
<BR>
If one does a scaling like this<BR>
\pstScalePoints(1,100){}{11.444 add}<BR>
with the psgraph <BR>
\begin{psgraph}[Oy=-11.444]{->}(4,0)(4,-2)(14,6){9cm}{5cm}<BR>
<BR>
then:<BR>
Dy = [(6 - (-2)) / (5 * 100)]<BR>
= .016<BR>
<BR>
<BR>

This is still not what I would like to have. However I now better
understand how the parameters should be set.
dy should be set to 5/6 as the real size of the graph is 5cm and that
the Oy axe is ranging from -2 to 4. The labels are thus correct only if
dy equals the ration between the real size and the Oy size.
Those are thus correct:
\begin{psgraph}[dy=0.833333333cm,Dy=0.010,Oy=-11.444,Ox=4]{->}(4,0)(4,-2)(14,4){9cm}{5cm}
\begin{psgraph}[dy=1cm,Dy=0.010,Oy=-11.444,Ox=4]{->}(4,0)(4,-2)(14,3){9cm}{5cm}
To summarize:
Dy and Oy: reflects the scaling done on the real data through
\pstScalePoints
dy: reflects the ration between the real graphic size and the Oy axe
length.
Herbert, as always your help is precious and accurate! Thank you very
much!
regards,
Antoine
