How I plot 3d graph of known x,y,z ?. First of all, Matlab stands for matrix laboratory, so it is important to remember that Matlab thinks in matrices. Toggle Main Navigation To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length. plot3d(z) draws the parametric surface z=f(x,y) where x=1:m, y=1:n and [m,n]=size(z) where m and n must be greater than 1. plot3d(x,y,z,[theta,alpha,leg,flag,ebox]) draws the parametric surface z=f(x,y). For example there may be some point 1,2 with a value of 67. Is there a way to visualise them with colours? This toolbar contains many options and features that can be used to manipulate your 3-D plot. I am sure it is easy but I can't find the answer in MATLAB help/Google. After reading the MATLAB 3-D plots topic, you will understand how to create 3-d plots as a surface plot or mesh plot in MATLAB. You're replicating the vectors x and y to create a set of matrices X and Y when you use MESHGRID, and since z is still a vector, and not a matrix of the same size as X and Y, you can't plot a mesh. Learn more about 3d plots, graph What does plot do? How to swap between X, Y and Z in 3D plot . Thanks, Jo. A 3-D plot will consist of an x-y grid with discrete z values for each x-y point. I have tried simple things such as: matrix=xlsread(filename); surf(matrix); or matrix=xlsread(filename); X = matrix(:,1); Y = matrix(:,2); [x,y]=meshgrid(X,Y); Z = matrix(:,3); surf (x,y,Z); but here I get the following message: 'Z must be a matrix, not a scalar or vector', Any help with the coding would be appreciated, I am just trying to visualise some results.
