[Xy-pic] plotting a curve

[Sven Hartrumpf]

Hi all.

I am trying to plot a curve using xy-pic; the xyc.tex file is at the end
of this mail (also at: http://pi7.fernuni-hagen.de/hartrumpf/xyc.tex )

The result (http://pi7.fernuni-hagen.de/hartrumpf/xyc.pdf) is not perfect
yet:

- the curve does not stop were it should (returns somehow)
- the axes are not as long as expected
- I would like to shift the symbols on the axes a little bit.

Thanks in advance
Sven
