Contour Plot for Scattered Data



Triangular Contour Plot

File Information

TRICONTOUR(TRI,X,Y,Z,N) draws scalar N contour lines treating the values in Z as heights above a plane. TRI,X,Y,and Z define a triangulation where the triangles are defined by the M-by-3 face matrix TRI, such as that returned by DELAUNAY. Each row of TRI contains indices into the X,Y, and Z vertex vectors to define a single triangular face. Contours are computed directly from the triangulation rather than interpolating back to a cartesian grid using GRIDDATA.
TRICONTOUR(TRI,X,Y,Z,V) draws length(V) contour lines at the values specified in vector V.
TRICONTOUR(TRI,X,Y,Z,[v v]) draws a single contour line at the level v.
[C,H] = TRICONTOUR(...) returns contour matrix C as described in CONTOURC and a vector of handles H to the created patch objects.
H can be used to set patch properties.
CLABEL(C) or CLABEL(C,H) labels the contour levels.

Very useful, Thank you!

It is a pity MATLAB doesn't have a function like that yet. I usually avoid using functions from fileexchange but this one was really necessary for me. Smart way of leaving the option to insert the values for the contours, as I have a figure from parts so I can fix the values and keep the contours continuous

Useful function in order to display contour lines from a TIN (equivalent to a Delaunay triangulation) without converting the TIN into a regular mesh.

Exactly what I was looking for.
