How to plot amplitude values of a matrix (dimension 651 by 10) with colorcode

I have amplitude values of a matrix with dimension 651*10. Also, I have the cluster number for this matrix with 1 to 5. I want to plot these Cluter number with specific color like 1 is green, 2 is black, 3 is cyan, 4 is red, 5 is white with its amplitude values. Means this amplitude values will be clustered by this mentioned colocode. How to plot this. Please, help me with useful information. thanks

So you want to plot, all the amp datas when cluster data equals 1, 2, 3, 4, and 5? You can easily obtain the corresponding data with logical indexing.

But, in that case, what will be the corresponding x values for the plots?

Yes. But unable to do.

@AS: "what will be the corresponding x values for the plots?" In other words, you want to plot amplitude vs ____ ?

How about this?

load('amp.mat')
load('cluster.mat')

colors = 'gkcrw';
for ii = 1:5
    idx = find(cluster == ii);
    plot(idx,amp(idx),[colors(ii) '.']);
    hold on
end
set(gca(),'Color','y');
