-"The scree plot beneath the dendrogram has a point for each cluster join. The ordinate is the distance that was bridged to join the clusters at each step. Often there is a natural break where the distance jumps up suddenly. These breaks suggest natural cutting points to determine the number of clusters."
--ordinate: vertical axis (y-axis) (as opposed to the abscissa)
--A scree plot is a graphical display of the variance of each component in the dataset which is used to determine how many components should be retained in order to explain a high percentage of the variation in the data.

sentences I had in my dissertation about a scree plot, but then removed
"At the bottom right of the heatmaps there is a scree plot beneath the dendrogram for the hierarchical clusters of the samples. The scree plot has a point for each cluster join. Often there is a point where the distance between the points jumps suddenly, and this break is used to suggest a level of the hierarchical clustering that is most appropriate to cluster the samples by."
