I have clustered my image into 8 different clusters

pixel_labels = reshape(cluster_idx,nrows,ncols);
imshow(pixel_labels,[]), title('image labeled by cluster index');

but I want to display 8 different colors something like . . .

imshow(pixel_labels,'colormap', hot(8))

then show the colorbar

I know this should be easy but can't figure it out

thanks

Charlie
