Problem with autoscale, data and function

[Jan S. <jan...@gm...>]

Hi,

today i've got stuck with a problem in gnuplot 4.4.2. On freenode i was
suggested to post it here as it seem to be a bug. Here is my problem,
some data and a function:

In the first example using autoscale the function ends on the sheet
without reaching the boarder, when using x/yrange, it shows the right
behaviour.
As i want to use autoscale (with set xrange [0:*]) and as output eps, i
tried to find a workaround. Using replot f(x) works but i ran in another
problem, as epstopdf don't convert the resulting eps right, the pdf is
missing the function (this might be a epstopdf problem).

Thank you,

Jan
