[Gnuplot-info] cilinder

[Carles P. i E. <ca...@pi...>]

Hi,

Now I can plot sphere using cartesian system, but I need cylinder too
(and this is the last figure that I have problems :-)   )

Ok, cylinder in cartesian system is:
x**2 + y**2 = R

Of course, I have tried:
cilindre(x,y)=x**2+y**2-1.0
splot cilindre(x,y)
pause -1

But doesn't work (normally!). I had the cylinder in:
---------
set mapping cylindrical
set parametric
set isosample 20
R1=2
desplx1=0
desply1=0
splot R1*cos(u)+desplx1,R1*sin(u)+desply1,v
---------
But I need in cartesian system to plot cylinder and other figures in
same graphic. 

Any idea to have the cylinder in cartesian system and not parametric?

Thank you very much!
