contourf (Z) creates a filled 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. The column and row indices of Z are the x and y coordinates in the plane, respectively. contourf (X,Y,Z) specifies the x and y coordinates for the values. .The surface plot uses Z for height and C for color. Specify the colors using a colormap, which uses single numbers to stand for colors on a spectrum.When you use a colormap, C is the same size as Z.Add a color bar to the graph to show how the data values in C correspond to the colors in the colormap

Surface plot form 1d data . Learn more about 2d mes How to show surface plot of 2D data?. Learn more about surface, surf, contou
The surf function expects a matrix, so you will have to convert your linear data to a matrix. The accumarray function is a very flexible tool and worth exploring if you've never seen it before. A general advice would be to read the documentation for functions you are trying to use, and read the related functions linked at the bottom if you think it doesn't quite do what you need If I have a 2D plot that is defined by two separate functions, such that the resulting plot is not a function, how do I create a surface of revolution of the plot by rotating that curve around the x-axis? For example, consider the plot generated by executing the following: x = -1: .01: 1; plot(x,acos(x)+4) grid on. hold on
In MATLAB, we can plot different types of modules like 2d plotting and 3d plotting. In this article, we will see what are the various types of 3D plotting. Mesh Plot: A mesh plot is a 3d surface that creates different types of meshes for different types of expression. To create mesh we have to give the values x and y for z, (z= f(x, y)) I just came across this same problem. I have evenly spaced data that is in 3 1-D arrays instead of the 2-D arrays that matplotlib's plot_surface wants. My data happened to be in a pandas.DataFrame so here is the matplotlib.plot_surface example with the modifications to plot 3 1-D arrays I have a contour plot in 2D which I would like to put on a cylinder. That means that one direction of my 2D plot is the axial direction(z) and the other one is the azimuthal direction(phi) (in radiant). For the Radius I would like to use the value of 0.5. For phi, z and the data I want to plot I have 3D data: 1st dimension: z-directio 2D 'Surface Plot' from 3D geometry. Hi, Is there any way to create a 2D surface plot of a slice of a 3D geometry. For example creating the 2d heatmap plot from the 3D at a specific Z slice (here at z=0 if z = [-25:25], i.e. slicing it in half. p.s. the 2D plot here was created by creating an entirely different 2D geometry as a visual aid

. I want to do a 2D plot based on 3 columns of data (X,Y and Z) . X column show positions, y column show speed and z column show emissions. I guess first I should make meshgrid between x and y then show the z values on this 2D plot. I want to have a result like the bottom of this image A 2D array is like an image. If you plot that as a surface where the Z value is the gray level and you make a perspective rendering of it, like you get with surf (), then that's kind of like a 2.5D plot. It's not true 3D because there is not a Z value for each x,y pair. A true 3D image would be like a volumetric image like a CT or MRI medical.

Defining the domain here is even trickier than for 2D. You don't want too few points in the grid or it will appear jagged, but too many and the computer will slow down or even hang Rough surface generation & analysis. Surface roughness is a measure of the topographic height variations of the surface. The roughness can arise from polishing marks, machining marks, marks left by rollers, dust or other particles and is basically shaped by the full history of the surface from the forming stages (casting, sintering, rolling, etc.) to the finishing processes
Afterwards, use the SURF function to generate the surface plot. [x y] = meshgrid (-1:0.1:1); % Generate x and y data. z = zeros (size (x, 1)); % Generate z data. surf (x, y, z) % Plot the surface.
