[pstricks] Problems calculating the units in a diagramm with various plots

[Martin Buchmann]

Hi all,

i try to plot some data in one diagram which is comes on different 
scales, i.e. concentration and temperature over distance using two y-axis.

I have two files which i want to plot via the fileplot command and 
thought that i could manipulate the yunit of the second command so that 
all data could fit in one plot but the scaling is always wrong. Is it 
possible at all to do this or am I missing something in the basic logic 
of my plot?

Best regards
   Martin
