#Matlab 2014a plot cycle through colors how to#

For example, to generate 10 'maximally perceptually-distinct colors' and use them for 10 plots on the same axis ( but not using ColorOrder, thus requiring a loop): % Starting with X of size N-by-P-by-2, where P is number of plots Of course, you can set the ColorOrder for a single axis or simply generate a list of colors to use in any way you like. They even made the excellent suggestion to set MATLAB's ColorOrder on startup to, distinguishable_colors(20)

The GMPDC submission was chosen on MathWorks' official blog as Pick of the Week in 2010 in part because of the ability to request an arbitrary number of colors (in contrast to MATLAB's built in 7 default colors). Given an initial large list of possible colors, it iteratively chooses the entry in the list that is farthest (in Lab space) from all previously-chosen entries.ДЇor example, when 25 colors are requested: This function generates a set of colors which are distinguishable by reference to the 'Lab' color space, which more closely matches human color perception than RGB. It is best described in the author's own words: For 10 plots, you obviously cannot rely on the default ColorOrder.ДЄ great way to define N visually distinct colors is with the 'Generate Maximally Perceptually-Distinct Colors' (GMPDC) submission on the MATLAB Central File File Exchange.

However, by default MATLAB only specifies a short list of colors ( just 7 as of R2013b) to cycle through, and on the other hand it can be problematic to find a good set of colors for more data series.

The ColorOrder axes property allows MATLAB to automatically cycle through a list of colors when using hold on/all (again, see Appendix below for how to set/ get the ColorOrder for a specific axis or globally via DefaultAxesColorOrder).

There is a great tool on the MATLAB Central File Exchange to generate any number of visually distinct colors, if you have the Image Processing Toolbox to use it.

For information on how to change the 'ColorOrder' property and how to set a global default with 'DefaultAxesColorOrder', see the 'Appendix' at the bottom of this post.

MATLAB uses the number to calculate indices into theДЇor example, create an axes object with two colors in itsД¬olorOrder array (red and blue) and two line styles in its Object's order of creation, starting at 1. SeriesIndex property is a number that corresponds to the LineStyleOrder arrays, the colors, line styles, and markersДЇor a particular plot object are determined by the value of the object's SeriesIndex, which If there are more objects thanД¬ombinations of colors and character sequences, then the cycle repeats. TheД¬ycle continues for each new plot object.

The LineStyleOrder array before the next sequence is used. LineStyleOrder array contains only the solid line style,Д¬olorOrder array are used with one character sequence in Line style (or a line style combined with a marker). The LineStyleOrder property contains aД¬ell array of character sequences, where each character sequence corresponds to a If the plot objects support line styles and markers, MATLAB also cycles through the list in the LineStyleOrder Objects than there are colors, the colors repeat. The defaultД¬olorOrder array contains seven colors. Triplets, where each RGB triplet defines a color. The ColorOrder property contains an array of RGB Through the colors listed in the ColorOrder property MATLAB assigns colors to plot objects (such as Line, Plot colors and line styles in an earlier release, see Why Are Plot Lines Different Colors? and Line Styles Used for Plotting - LineStyleOrder.
