Objects names in dendrogram

Hello, I didn't find a way for labeling the objects in a dendrogram.

The code I'm using is like this:

A = dataset('XLSFile','MyExcelFile.xlsx');
MyVars = double(A(:,{'Var1', 'Var2', 'Var3'}));
clustVars = pdist(MyVars,'euclidean');
linkVars = linkage(clustVars,'average');
[h,nodes] = dendrogram(linkVars,0);

1. Load the Excel file into a dataset array
2. Create a double-precision array containing the variables
3. Compute the Euclidean distance
4. Execute the clustering method
5. Draw the dendrogram

In my dataset array A I have a variable that contains the names of the vectors.

Of course I can't include that variable in the analysis.

Can somebody explain me how to label the objects in a cluster analysis using that variable, let's call it objNames?

Thanks in advance,

Diego

Well this way I can put the names of the objects in the tree

S = cellstr(A(:,{'objNames'}));  
[h,nodes] = dendrogram(linkVars,0,'labels',S);

However the horizontal orientation of the names doesn't allow me to read them.

How can I rotate the names to a vertical orientation?

Thanks

... and this way seems to be better for clarity:

[h,nodes] = dendrogram(linkVars,'colorthreshold','default');
find(nodes==29)

How can I add the names of the objects directly with the find function?

Well this seems to work good enough:

A = dataset(find(nodes),nodes,S)
sortrows(A,2)
