I’m trying to present some data by using a dendrogram.

I would want to create clusters by calculating the distance (or “similarity”) between different entries. I create a first cluster with the 2 entries which are the closest, and so on.
The image bellow is the kind of diagram I would like to obtain.

I searched the Root documentation but didn’t find the dendrogram. Is there a Root class that I could use to get something close or equivalent to that ?

Thanks in advance.

This kind of plot is not available in ROOT right now. But we can think implementing it.
There is many references on the web.

Ok, thank you for your answer. I’ll try to use another method.
