The plot is formed by joining adjacent points with straight lines. The surface always passes through the data points defined by x and y. surface(Z) plots the Surface specified by the matrix Z. Surface plots are created by using ax. The griddata function interpolates the surface at the query points specified by (xq,yq) and returns the interpolated values, vq. . The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. With plot3, what you need to do is make the y values for each of your plots z values instead, and if you want to separate the graphs, you need to vary the y values in this 3D plot. The color of the surface varies according to the heights specified by Z. and at each point I have the resultant value measured by experiment. If you accidentally use 0 as the z coordinate or use plot() instead of plot3(), then the line would be hidden behind any part of the surface that had a positive z value. I would like to 2d surface plot matlab. contourf(Z) creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane. Oct 2, 2016 · surf(Z) creates a three-dimensional shaded surface from the z components in matrix Z, using x = 1:n and y = 1:m, where [m,n] = size(Z). The value is represented by color and the 2 variables as the 2 axis. MATLAB can create Apr 2, 2013 · Once I read the data in, I use mesh() to make a plot. The curvature of the object however is not smooth everywhere. MATLAB ® automatically selects the contour lines to display.

I am using the contourf function to plot my data: clc; clear; load('da Mar 29, 2025 · MATLAB Graphics 2-D and 3-D Plots Surfaces, Volumes, and Polygons Surface and Mesh Plots Find more on Surface and Mesh Plots in Help Center and File Exchange Tags Jul 13, 2016 · If the normal vector of the plane you want to slice your surface will always lay in the xy plane, then you can interpolate the data over your surface along the x,y coordinates that are in the slicing line, for example, let the plane be defined as going from the point (0,15) to the point (50,35) vq = griddata(x,y,v,xq,yq) fits a surface of the form v = f(x,y) to the scattered data in the vectors (x,y,v). There are similar plots for other x values as w Jul 6, 2019 · You can use plot3 to help you facilitate this kind of plotting. plot_surface(X, Y, Z) where X and Y are 2D arrays of points of x and y while Z is a 2D array of heights. Jul 29, 2022 · To get a surface, set up regular coordinates over the appropriate range for cp12x and cp12y, then use meshgrid to get a matrix, then interp2 to interpolate to find appropriate values of your magnetic field at those mesh points. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The height, Z, is a single-valued function defined over a geometrically rectangular grid. fit sets the extrapolation method to "linear" when you set ExtrapolationMethod to "auto" for "linearinterp" curve fits. fsurf(f,xyinterval) plots over the specified interval. 2d surface plot matlab.
