This video shows how to put an individual text label on each of a series of points. MATLAB provides a variety of plotting routines, both in 2D and 3D. 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. As it is still difficult (impossible?) You can use the scatter plot data as input to the TEXT command with some additional displacement so that the text does not overlay the data points.

This video shows how to put an individual text label on each of a series of points. plot3. i.e., the the last 2 coordinates (#[[{2,3}]]) of data points. The official way would be to use: ax.tick_params(axis='z', pad=50) ax.set_zlabel(r'k_z...', labelpad=30) However, there is a bit of bad luck. I would like to visualize 3D data and have a little label next to each data point. Plots can be created using graphic functions or interactively using the MATLAB Desktop. clabel(C,h) labels the current contour plot with rotated text inserted into each contour line.The contour lines must be long enough to fit the label, otherwise clabel does not insert a label. generates a 3D scatter plot of points with a 2D array of height values.

Types of 3D Plots in MATLAB. For example, text([0 1],[0 1],'my text'). With tick_params the official API documentation for 1.3.1 says: While this function is currently implemented, the core part of the Axes3D object may ignore some of these settings. A line drawn with Matlab is feasible by incorporating a 2-D plot function plot() that creates two dimensional graph for the dependent variable with respect to the depending variable. Also in the second one, the label goes beyond the bounds of the axes. For example, I have the coordinates for one point is 0.2,0.3,04 and for another point is -0.3,0.3,0.1. Plot Types.
