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:


To summarize:
Dy and Oy: reflects the scaling done on the real data through
dy: reflects the ration between the real graphic size and the Oy axe

Herbert, as always your help is precious and accurate! Thank you very
