I made this dendrogram and for some reason it puts all the labels on top of one another. I’d like to know how to make it readable and space the labels from one another. The colors are there to differentiate between 4 groups found after a cluster analysis on my original data.

I tried playing with the plot margins using the fonction par() but it didn’t solve my problem. I also tried to put it horizontally but it didn’t work either.
