If you find another use for this technique, let us know in the comments. This nontraditional use of colorbar works pretty well as an auxiliary color label for the x-axis (or y-axis). The final tweaks set things up so that the x-axis labels appear under the colorbar. I also need to set the CLim property to establish the relationship between the colormap colors and the spectrum wavelength values. The colorbar automatically picks up its colors from the axes Colormap property, if it is set, or from the figure Colormap property. plot (X,Y,LineSpec) creates the plot using the specified line style, marker, and color. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Above function plot the dots but how I change the dots color red or. Let's just start with a plot and a colorbar with the default settings. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. The entire set of DIPUM3E functions is also on GitHub. On each plot, clearly denote the quantum numbers that specify the wave functions whose probability density you plotted. These techniques are used in the DIPUM3E functions spectrumBar and spectrumColors, which are available to you in MATLAB Color Tools on the File Exchange and on GitHub. Today I'll finish up by explaining the use of the colorbar function. In my July 20 post, I showed one way to compute the spectral colors to display below the x-axis. We can find RBG vector value at any point on a particular image. We can isolate a single color from any image while all other colors are set to 0. Recently, I've been explaining how I made this plot, which is from DIPUM3E ( Digital Image Processing Using MATLAB, 3rd ed.): ‘Colormap’ command in MATLAB software can be used for the following purposes: It has the function of color scheme editing of an image, figure,plots, mesh etc.
