[pstricks] psgraph pstScalePoints and labels

[Antoine Pairet]

Thanks for the quick answer. However it is not want I need. Maybe I was
not clear enough.


> \begin{psgraph}[Dy=1.000,Oy=-11.444,Ox=4]{->}(4,0)(4,-2)(14,4){9cm}{5cm}


This will make the labels to be equal to -11.444, -10.444, -9.444 etc.
Want I'd like to have is the same scaling on the points I'm plotting on
the labels of the psgraph env.

The labels should evolves this way: -11.444, -11.434, -11.424 etc. At
each step an increment of .01 should be added. This way the labels would
be coherent with the scaling performed on the data by the command
\pstScalePoints(1,100){}{11.444 add}.

I will provide three examples in the hope everything is more clear:
 1. original example
 2. example where the label values where "hardcoded" using \psyTick(){}
=> target behaviour
 3. example 1 with technique of example 2; because of Ox=4, this does
not work, \psyTick places the tics and the labels at x=0

What I am looking for is a automation of the process used in the second
example that works even if Ox /= 0.
Attached is the PDF of the output.

Thanks in advance,
Antoine Pairet
