Oups. I meant to say "tried". I have a plain installation of cygwin (binaries 
only - no sources here...) and have used it successfully for a while. Today I 
thought I could use gnuplot to visualize some graphs for my weatherstation.

Yes I have the manual and I have read it too. I thought my original problem 
(not seeing any graphs at all) was tightly coupled with the missing file output.

Now, I found out that I must start x before running gnuplot! If I start x and 
the plot sin(x) a nice sinus curve is drawn on screen :-)

However, the output to file does still not work?!
Here is what happens:
gnuplot> set output "sinus.jpg"
gnuplot> plot sin(x)
winProcEstablishConnection - Hello
winProcEstablishConnection - Clipboard is not enabled, returning.

This makes no sense to me :-(
A file sinus.jpg is created - but it is empty (size=0).

Two questions:
1) How do I work around the erroneous behaviour above?
2) Must x really be running for gnuplot to output graphic files?
