Figure 6
Clustering results of the 2D UMAP plots. Results for (a) $[2 {\overline 2} 02]$ and (c) $[2 {\overline 2} 00]$ are listed. Clusters in panels (a) and (c) are colored according to their labels. The elliptical arrow curve represents a guide to the eye to illustrate the continuity of the cluster distribution. (b), (d) Mapping of the UMAP clusters into the nanoXRD measurement area. Mapping colors in panels (b) and (d) are linked to the clusters in panels (a) and (c), respectively.
