Representing data from *.txt file in 3D graph

Hello,

I have a set of data representing a temperature Profile (Matrix) which contains 18 Points in 20mm=X, 15mm=Y and z represents the temperature in These Points, What i want to do is to represents those Points (z) in a 3D Graph where X and Y are the surface length and z represents the height. does anyone know how to do it ?

Thanks

Moh

20mm=X, What does that mean?

3D graph X = Length in x axis, Y= Lenght in y axis, and what i want to represent is the temperature as z in this surface (XY)

read the data in. reshape() and transpose() it if necessary. Then use surf()
