For example: set(gca, 'Projection', 'perspective') 3 Comments. On some occasions, a 3d scatter plot may be a better data visualization than a 2d plot. scatter3(X,Y,Z,S,C) displays colored circles at the locations specified by the vectors X, Y, and Z (which must all be the same size). I am using the "Globe Projection", which gives me a 3D spherical map, however the "scatterm" function does not work. After looking in several different sources, and across the breadth of previous questions such as How does a projection Matrix work?, I've found that most solutions seem to use the following two matrices;.

If C is a three column matrix with Thus, the color codes This … You triangulate these projections of the vertices on x-y plane, but some obtained triangles are not the projections of the real triangles on the surface. For example: I want to plot (x1,y1,z1) in red, (x2,y2,z2) in yellow, (x3,y3,z3) in blue. followed by three or six hexadecimal digits, which can range What offset to use will require some thought that takes into account the various axes view properties such as camera target, and the DataAspect, and the [XYZ]Limit properties, so that after the projection due to the view is taken into account, the label becomes far enough away. So I need a 2D "web" of points. This function accepts GPU arrays, but does not run on a GPU. If C is a vector with length equal 'auto' option uses the same color as the Color property for the axes.
