Can Matlab handle this color scheme?

According to the data that I attached I plotted and colored the plot manually in order that it looks funky like this:

Question is: Can Matlab copy this colordesign? I know Right, this isn't a GraphicDesignProgram, just want to check its limits.

No data attached...but that's pretty-much immaterial.

Unfortunately, line isn't into the 21st century yet with a variable color attribute but you could mimic a similar appearance in quite a number of ways...

[Niklas Kurz]

Yea, it's irrelevant that data can't be load.

It's More frightening that color control is pretty hard in MATLAB if it is to be a gradient.

[dpb]

Well, what is the logic behind what was done there manually...

[Adam Danz]

Are you asking if that colormap can be created? Yes.

Are you asking about whether Matlab can plot smoothly transitioning gradients? Yes.

Here are some demos that mimic variable line color.

And here's a great blog post sharing some undocumented methods.

Color in the data you shared is clearly assigned according to the absolute value of y.

that's a helpful documentation, thank you. Serarched an eternity for something like this

[Adam Danz]

If your data are finely sampled, you could use scatter() instead of a line.

My first thought was to adapt something from the surf/patch family of functions.

See my answer here, where I vary the line color for two cases: along the y axis (which you want), and along the x axis.

clear all;
close all;
clc;
format long g;
format compact;
fontSize = 15;
fprintf('Beginning to run %s.m ...\n', mfilename);

x = linspace(0, 2*pi, 1000);
period = pi;
y = sin(2*pi*x/period);

numMarkers = numel(y);
markerColors = jet(numMarkers);
subplot(2, 1, 1);
for k = 1 : length(x)
	plot(x(k), y(k), '.', 'Color', markerColors(k, :), 'MarkerSize', 30);
	hold on;
end
grid on;
caption = sprintf('Line Color Varies Along X.  Composed of %d Differently Colored Markers', numMarkers);
title(caption, 'FontSize', 20);
xlabel('x', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
xlim([min(x), max(x)]);
% Maximize the figure window.
g = gcf;
g.WindowState = 'maximized';

% Do it again but instead of changing color as we move along the x axis, 
% change it as we go along the y axis.  So the marker color depends on the y value.
subplot(2, 1, 2);
numMarkers = numel(unique(y));
markerColors = jet(numMarkers);
miny = min(y);
maxy = max(y);
% Get indexes into the color map for each y value.
colorMapRows = round(rescale((y - miny) / (maxy - miny), 1, numMarkers));
for k = 1 : length(x)
	thisMarkerColor = markerColors(colorMapRows(k), :);
	plot(x(k), y(k), '.', 'Color', thisMarkerColor, 'MarkerSize', 30);
	hold on;
end
grid on;
caption = sprintf('Line Color Varies With Y Value.  Composed of %d Differently Colored Markers', numMarkers);
title(caption, 'FontSize', 20);
xlabel('x', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
xlim([min(x), max(x)]);

fprintf('Done running %s.m.\n', mfilename);

You can do something similar with scatter and the color vector.

It does seem like given the advances in computing and graphics/visualization TMW would have built a better mousetrap by now than having to resort to such workarounds at the user level.
