Matlab中的2D线条渐变色彩 [英] 2-D line gradient color in Matlab

问题描述

是否可以在Matlab中为2D线添加渐变颜色，特别是当您的数据点数少（小于10？）时，所以结果将类似于下图中的一个？

解决方案

这是如果你有MATLAB R2014b或更新的话，这并不难。

x = linspace（-10,10，n）; y = x。^ 2;
p = plot（x，y，'r'，'LineWidth'，5）;

％修改jet-colormap
cd = [uint8（jet（n）* 255）uint8（ones（n，1））]';

drawnow
set（p.Edge，'ColorBinding'，'interpolated'，'ColorData'，cd）

其结果如下：

Is it possible to add gradient color to 2-D line in Matlab, especially when you have small number of data points (less than 10?), so the result would be similar to one in image below?

解决方案

This is not difficult if you have MATLAB R2014b or newer.

n = 100;
x = linspace(-10,10,n); y = x.^2;
p = plot(x,y,'r', 'LineWidth',5);

% modified jet-colormap
cd = [uint8(jet(n)*255) uint8(ones(n,1))].';

drawnow
set(p.Edge, 'ColorBinding','interpolated', 'ColorData',cd)

Which results in:
