自动绘制不同的彩色线 [英] Automatically plot different colored lines

问题描述

我正在尝试在同一张图上绘制几个内核密度估计值，并且希望它们全部为不同的颜色.我有一个模糊的解决方案，使用字符串'rgbcmyk'并逐步处理每个单独的图，但是经过7次迭代后，我开始出现重复.有没有更简单/更有效的方法来实现这一点，并提供了更多的颜色选择?

I'm trying to plot several kernel density estimations on the same graph, and I want them to all be different colors. I have a kludged solution using a string 'rgbcmyk' and stepping through it for each separate plot, but I start having duplicates after 7 iterations. Is there an easier/more efficient way to do this, and with more color options?

for n=1:10
 source(n).data=normrnd(rand()*100,abs(rand()*50),100,1); %generate random data
end
cstring='rgbcmyk'; % color string
figure
hold on
for n=1:length(source)
 [f,x]=ksdensity(source(n).data); % calculate the distribution
 plot(x,f,cstring(mod(n,7)+1))  % plot with a different color each time
end

推荐答案

您可以使用诸如HSV之类的颜色图来生成一组颜色.例如:

You could use a colormap such as HSV to generate a set of colors. For example:

cc=hsv(12);
figure; 
hold on;
for i=1:12
    plot([0 1],[0 i],'color',cc(i,:));
end

MATLAB有13种不同的命名色图('doc colormap'列出了所有这些色图).

MATLAB has 13 different named colormaps ('doc colormap' lists them all).

以不同颜色绘制线条的另一种方法是使用 LineStyleOrder 属性；请参见MATLAB文档中的定义用于绘制线条的颜色更多信息.

Another option for plotting lines in different colors is to use the LineStyleOrder property; see Defining the Color of Lines for Plotting in the MATLAB documentation for more information.
