How can I modify the vertical scale? I noticed your leaves are at 0, but I cannot manage to do the same to mine

low_rect= 0

just found I can adjust the lower part of the rect easily with low_rect = value. thanks!

Hi, Kassambara

thanks for you reply. I may not be clear about what I mean. I still want to keep the colored blocks for each group on the branch, but I don’t want the color to cover the labels. Is there a parameter that can do the trick? thanks!

You need to specify the argument color_labels_by_k = FALSE.

# Load data
data(USArrests)
# Compute distances and hierarchical clustering
dd <- dist(scale(USArrests), method = "euclidean")
hc <- hclust(dd, method = "ward.D2")
# Visualize
library(factoextra)
fviz_dend(hc, k = 4, # Cut in four groups
          cex = 0.5, # label size
          k_colors = c("#2E9FDF", "#00AFBB", "#E7B800", "#FC4E07"),
          color_labels_by_k = FALSE)

The height of the fusion, provided on the vertical axis, indicates the (dis)similarity/distance between two objects/clusters. The higher the height of the fusion, the less similar the objects are. This height is known as the cophenetic distance between the two objects. Read more: https://www.datanovia.com/en/lessons/agglomerative-hierarchical-clustering/
