I don't where inputing this commands gets you a circle --- but it's not 
gnuplot.

Maybe you should explain why you "have problems drawing a circle" when 
you quite clearly already know how to do it?

OK, Sorry for the ambiguity,
What I meant was that I got those two functions of the web which 
supposedly draws a circle (but doesnt). Thats why Im asking how (or any 
other options) to draw a circle in gnuplot.
Thanks
Astan

New version, you beat me to it and no doubt did a
better a job, checked and working perfectly.

Let me know if I can be of any help.

In the page above there are one example that will probably help you to
draw a circle using gnuplot:

Gnuplot4.3 introduces a new function for drawing circle in this format
x y radius
