A search for "cluster" refined by Graphics in the File Exchange finds twenty contributions.

Look at the Description at that link. It describes exactly what each of the parameters means.

There are no clusters in that data because your data is uniformly spaced. Or there are 6 clusters with just one point in them, or one big cluster with 6 points. You don't really have aggregation or clumping of any of the points.

Huda, when I answered your other question, I suggested that you run 'doc linkage' and gave you a link to the web doc for that function. At the bottom of that page, you can see examples of two different plots. Are you asking for a plot that is not on that page?

Use gscatter.

Why not just use the scatter() function? If that doesn't work, then explain why not, and use more words to do it.

load fisheriris
d = pdist(meas);
Z = linkage(d);
c = cluster(Z,'maxclust',4);
Y = cmdscale(d);
gscatter(Y(:,1),Y(:,2),c)
