When I do this the 3D surface plot breaks down. I have z - matrix of 9 data points, which correspend to different combinations of values from an x-vector of 3 and a y-vector of 3. Surely, there must be a way to co-plot points onto a 3D surface plot? Learn more about 3d plots, surface plots, surface graphs from points Plot the expression f as a surface. Defining the domain here is even trickier than for 2D. Learn more about solid model stl 3d . Even in the absence of the plot3 command, just adding the hold on;/hold off; causes the surface plot to break down into a 2D heatmap. I have a predicted surface plotted in matlab and want to plot the real data in the same 3D space but don't know how. I would like to create something that resembles a surface plot, but I can not convert my Z into a matrix. You don't want too few points in the "grid" or it will appear jagged, but too … Learn more about surf, plot, 3d, 3d plots, for loop surf draws a colored parametric surface using a rectangular grid defined by X and Y coordinates (if {X,Y} are not specified, this grid is determined using the dimensions of the Z matrix) ; at each point of this grid, a Z coordinate is given using the Z matrix (only obligatory data).surf has been created to better handle Matlab syntax. Plot the surface using the surf command. Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions. I have a matrix Nx3 where each row represents X,Y,Z coordinates of points. Improve the appearance of the surface plot by using the properties of the handle returned by fsurf, the lighting properties, and the colormap.. Vote. Learn more about plot 3d sets Thxs. I am having trouble trying to make a surface plot out of given points. 3D surface plot from for loop. This is the point in which you will relate xx, yy, and zz together. Basic 3D Surface Example using SURF. Description. From the z components in the matrix "zz", the surf command will create a 3-D shaded surface. The meshgrid command is vital for 3D surfaces! ... How can I plot a 3D solid figure (not just 3d surface) Follow 47 views (last 30 days) lingfeng zhou on 18 Nov 2016. This example shows one way to plot 3D surfaces. I'm having trouble plotting a curve/surface of best fit through data points. The actual command line will be in the format of surf(xx,yy,zz).
