You clicked a link that corresponds to this MATLAB command: Run the command by entering it in the MATLAB Command Window. plot(x,y, 'o') text(x,y,labels, 'VerticalAlignment', 'top', 'HorizontalAlignment', 'left') But both of these aren’t exactly what I want because the labels slightly overlap the data. If you have three points in the scatter plot and want the colors Specify optional pair arguments in any order as Types of 3D Plots in MATLAB. Use plots to visualize data. When plotting 3D points, you can use the plot3 function which takes as its arguments 3 vectors representing the x, y and z coordinates. Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™. and Z must be vectors of equal length. A modified version of this example exists on your system. Plot3 (x,y,z): If x,y,z are vectors of the same length, then this function will create a set of coordinates connected by line segments. Create vectors x and y as cosine and sine values with random noise. scatter3(x,y,z,ones(size(x)),data,'filled') This will plot all the points at the same size and color them according to the value of data, using the current colormap. This table lists Plots can be created using graphic functions or interactively using the MATLAB Desktop. It is a 2D plot, but if you plot this in 3D you should get a plane and points. This tutorial illustrates how to generate 3D plots in Matlab. Set Scatter Series Properties Using Handle, Run MATLAB Functions with Distributed Arrays. For example, you can compare sets of data, track changes in data over time, or show data distribution.
