Thread Subject: combining two graphs into one

Hello,
I have two graphs in 2D but want to combine them into one
3D using matlab. How can i do this please help Thanks

"combine them" -how-? I can think of a number of different ways
to combine two 2D graphs into a 3D graph. For example, given
images (or drawings) of the same object from two different positions
(known relative to the object), it is not uncommon to wish to "combine"
the two images or drawings to model what the original object looks
like in 3D.

-Exactly- what kind of objects are used in the graphs? And what
do you expect their spacial relationship to be once in 3D ?

Hi Walter,
Thanks for the reply, it didn't show on my mail that is why
it has taken me sometime to reply. well I am faced with a
problem and that is how can i draw a 3D graph out of two 2D
graphs. I am using a bessel equation with two varing fields.
Using the meshgrid function does not give me the expected
graph. if u have basic knowlege in Physics then i can send
you the equation and the graphs so that u can see where i
have gone wrong.

I am unable to be of further assistance until you answer
the questions from my previous response. I am still left with
no clue as to what kind of handle graphic objects are present
in your 2D graphs, or as to what kind of handle graphic objects
you want the resulting 3D graph to be.

Walter,
I am having a similar problem that Kwadwo had. The 2d plots I am trying to concatenate into a 3d volume are field maps of a magnetic field. I started with a 64x64x64 matrix whose values displayed the field strength at the coordinate mentioned and I wish to graph them as a 3d volume, into which I can zoom and rotate. I am trying to use imagesc to get the 2d slices for each z value and then concatenate them together. Is this possible, and if so, how should I go about doing it?
Thank you
