Hi
I am trying to have two temperature profiles (two contours) on the same figure. But I want to define specific temperature isotherm for example for both I want temperature 18 C to be shown to see where they are and compare them.
I am wondering if anyone has any idea about that.
I would appreciate it if you help me.
Regrads,

See the contour documentation section on levels for details. To plot contours at 18°C, that would plot as:
contour(X,Y,Z, [1 1]*18)
For contours from 10°C to 20°C:
contour(X,Y,Z,10:20)
To get the (X,Y) data from the contours you want after creating them, see the documentation on contour matrix M. .
