# MATLAB: 3D plot of data

3d plotsMATLAB

Hello.
I have a data set consisting of stresses accociated with a coordinate point (x,z). The data is attached, note that all the y coordiantes are the same, ie the stresses are on a flat surface consisting of x and z. The data for the stresses are in colum B.
I would like to create a 3D plot or surface of my stresses, but I am unsure how to associate my stresses with a specific point, so that I can plot them. I have tried using meshgrid and surf, but not with any kind of sucess worth attaching.

``[num,txt,raw] = xlsread('Data_3Dplot.xlsx') ;num = num(9:end,:) ; nodes = num(:,1) ; value = num(:,2) ; x = num(:,3) ; y = num(:,4) ; z = num(:,5) ; scatter3(x,y,z,10,value,'filled')``
``[num,txt,raw] = xlsread('Data_3Dplot.xlsx') ;num = num(10:end,:) ; nodes = num(:,1) ; value = num(:,2) ; x = num(:,3) ; y = num(:,4) ; z = num(:,5) ; dt = delaunayTriangulation(x,z) ;t = dt.ConnectivityList ; p = dt.Points ; p(:,3) = value ; trisurf(t,p(:,1),p(:,2),p(:,3));view(2)shading interp ; colorbar``
