Complete Time-heated dendrogram of the 125 main spectrum profiles of S. pneumoniae illustrating the use of leaf label coloring. The colorscale shows the case recency, from to most ancient (blue color) to the most recent (red color), and then case concomitance. The interest cluster (red square) is indicated with an enlargement of the dendodragrm illustrating the possible leaf labelling using surveillance data. The stars near the leaves are the spectra involved in the alarm emitted by BALYSES
