Real data is not always on a nice X,Y grid, but the MATLAB commands SURF and MESH expect them File Exchange Pick of the Week. MATLAB Projects. Hans on IoT. ThingSpeak Library for Arduino. I tried to figure out how to generate surface plots for non-uniform data a couple of times before but never found somebody who was able to explain it. Apr 25,  · How do I plot a contour map of non-uniform x,y,z data? Asked by James Waineo. James Waineo (view that. From what I read, meshgrid should be used to interpolate the data, but I can't get it to work. I can create a grid for x and y, but the z (height) values don't line up with any of the new grid points. Matlab has a function called. Jun 08,  · I wanted to make a contour plot of this to map the performance of the motor. Since it's real data, M and omega are nonuniformly spaced. I found a lot of examples of how to interpolate data on a grid to help Matlab to create contour plots of nonuniformly spaced data. I used these, but I get a wiggly contour plot which doesn't seem right at all.

Contourplot with nonuniform data leads to strange interpolation? of how to interpolate data on a grid to help Matlab to create contour plots of. This function allows non-uniform contour levels contourf/imagesc/pcolor. 1 Rating x: x-coordinates of grid, vector or 2d matrix y: y-coordinates of grid. I am struggling for a couple a days on an issue. I have an irregular and non- orthogonal grid (see image attached) characterized by the x and y vectors giving the. Contour and contour3 seem to require a full, evenly spaced n x m array of points for x, y, and z, but I don't have that. From what I read, meshgrid. I have arrays data from COMSOL for a non-uniform mesh: x,y node positions and u for each node, where the nodes are refined in one area. Learn more about grid, sparse, interpolate data, non equally spaced, not equally spaced data, matrices, contour, surf. MATLAB Answers. MATLAB Central The problem is that the data is not a full uniform grid, but sparse.

Jul 16,  · I am struggling for a couple a days on an issue. I have an irregular and non-orthogonal grid (see image attached) characterized by the x and y vectors giving the position of the middle of each mesh and the data(x,y). They are non uniformly spaced grids, and I want to plot a filled contour that is colored by a, b in this case. Because of the arrangement of the points and non uniformity, I cannot use valdostamac.comid (correct me if I am wrong). How do I plot a column vector as a contour with non uniform grid points that are also column vectors? MWE. May 26,  · I have arrays data from COMSOL for a non-uniform mesh: x,y node positions and u for each node, where the nodes are refined in one area. I want to create a 2-D contour plot of this data in MatLab on an x-y graph and colors representing u.
