Oct 4, 2022 · To plot data with density, you can have your data converted to matrices and use the mesh and surface plots. More on this can be found here, https://www.mathworks.com/help/matlab/surface-and-mesh-plots-1.html

This example shows how to create a variety of 3-D plots in MATLAB®. The mesh function creates a wireframe mesh. By default, the color of the mesh is proportional to the surface height. The surf function is used to create a 3-D surface plot. The surfl function creates a surface plot with colormap-based lighting.

Apr 12, 2012 · This gave me the joint density plot in 3D. Which can be checked by calculating the integral over the surface with: integralOverDensityPlot = sum(trapz(pdf_normalize)); When the variable step goes to zero the variable integralOverDensityPlot goes …

Aug 5, 2019 · Here is a way to count the 3D density of a point cloud. Although I am affraid the sample data you provided do not yield the same 3D distribution than on your example image. To count the density, the approach is broken down in several steps:

Jul 17, 2015 · One way would be to use a 3D scatter (bubble) plot, with variable circle/bubble sizes, proportional to the intensity of your particle. Here is a simulated example: N = 1e4; % number of particles X = randn(N,1); % randomly generated coordinates Y = 2*randn(N,1); Z = 0.5*randn(N,1); S = exp(-sqrt(X.^2 + Y.^2 + Z.^2)); % bubble size vector ...

May 20, 2022 · Visualize the density of points described by two variables X and Y, as a smoothed 3D surface plot.

To draw the 3D kernel density estimate plots, the ParaMonte visualizer utilizes the contour3() function of MATLAB. One can pass pairs of (key,value) properties to this MATLAB function by defining those keyword properties in the contour3 component of the plot object.

May 5, 2012 · I have a dataset consisting of a large collection of points in three dimensional euclidian space. In this collection of points, i am trying to find the point that is nearest to the area with the highest density of points. So my problem consists of two steps: 1: Determine where density of the distribution of points is at its highest

Jul 17, 2015 · The question is: how one can produce a 3D (spatial) density map of these particles, preferably in Matlab or Origin Pro 9 or ImageJ? Is there a way to, say, take the average of these images based on the red-color intensity in ImageJ?
