Dear Patrice,
I see.

but where is the sense to use these arguments when having
\xLabels?

   \multido{\nA=0+1,\rA=0+\psk at Dx}{\pst at pmtempe}{%
      \ifdim \nA pt < \z@ \def\nB{-\nA} \else \def\nB{\nA} \fi
	\uput{\psxlabelsep}[\pst at tempC]{\pst at xLabelsRot}(\rA,0){%
           \strut\expandafter\pshlabel\expandafter{\psPutXLabel{\nB}}}}%

what is the meaning of "\nA pt < \z@"? \nA is by default a natural
number and cannot be negativ. Maybe you mean "\rA pt < \z@"??
