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. z=1:0.01:1000; %More number of points to make a cylinder x=sin(z); y=cos(z); plot3(x,y,z); A 3D cylinder using plot3 function We can use plot3 to plot any 3 vectors in this way Also, we can add titles, labels, legends, xaxis, yaxis, thickness and many more like we add them to 2D plot.

This toolbar contains many options and features that can be used to manipulate your 3-D plot. An Example of 3-Dimensional Plotting in Matlab This example will produce this 3-D plot. Using Slices of a Matrix to Create 3D Plot. I want z to be used for the color data and surface height. 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. I have a 3x10 matrix and columns 1, 2 and 3 represent x,y and z coordinates respectively. To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length. I also have a contourf surface (which is basically a 2D plane).. 0 ⋮ Vote. The data is attached for your reference .. z= Number [2220.6 0 0 0 0; x 1160.4 1106.3 0 0 0; 524.2 0 0 0 436.4909]; z= [ 2220.6 0 0 0 0, 524.2 0 0 0 436.4909], You may receive emails, depending on your. Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y). plot3d(xf,yf,zf,[theta,alpha,leg ,flag,ebox]) draws a surface defined by a set of facets. contour3(Z) creates a 3-D contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane.MATLAB ® automatically selects the contour lines to display. I want to move the contourf plot to z=-10 (or any value on z-axis) but I can't do it.. Like a surface plot? There is a toolbar at the top of the window where the new plot has appeared. I was wondering if there is a way to do it. 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). Learn more about isosurface; 3d-printing, solidworks . How I plot 3d graph of known x,y,z ?. Follow 232 views (last 30 days) Hossam Selim on 7 Mar 2018. What does plot do? surf(X,Y,Z) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors.The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y.The color of the surface varies according to the heights specified by Z. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors.
