Hey, this question is pretty old,but I want to know something similar. You can apply different data labels to each point in a scatter plot by the use of the TEXT command. [0,1]; for example, [0.4 0.6 0.7]. It has additional parameters for positioning the label in reference to the data points (north, south, east etc) and has an option of adjusting axis limits if a data label is running off the plotted area. The scatter function maps the elements in c to colors in the current colormap. The 'filled' option sets the MarkerFaceColor property This function operates on distributed arrays, but executes in the client MATLAB. must equal the length of x and y. Vector — Use different colors for each marker scatter(___,mkr) specifies The goal is to plot several different relationships in the same figure and to include the labels for each of the points. components of the color.
