I'm having trouble plotting a curve/surface of best fit through data points. 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 would like to create something that resembles a surface plot, but I can not convert my Z into a matrix. Surely, there must be a way to co-plot points onto a 3D surface plot? ... How can I plot a 3D solid figure (not just 3d surface) Follow 47 views (last 30 days) lingfeng zhou on 18 Nov 2016. Plotting high quality 3D surfaces from points. 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. This example shows one way to plot 3D surfaces. 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. From the z components in the matrix "zz", the surf command will create a 3-D shaded surface. Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions. Plot the surface using the surf command. The actual command line will be in the format of surf(xx,yy,zz). I have a matrix Nx3 where each row represents X,Y,Z coordinates of points. Description. This is the point in which you will relate xx, yy, and zz together. Learn more about surf, plot, 3d, 3d plots, for loop Learn more about solid model stl 3d . Thxs. When I do this the 3D surface plot breaks down. 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. I want to create a surface plot by using the custom equation from variable ft and create surface from it that will fit to the data. 3D surface plot from for loop. Plot the expression f as a surface. Defining the domain here is even trickier than for 2D. I am having trouble trying to make a surface plot out of given points. Basic 3D Surface Example using SURF. Vote.
