Application of umap

Hi, I’m applying umap on my dataset. The reference is Updated Notebook with example of UMAP by davibarreira · Pull Request #44 · dillondaudert/UMAP.jl · GitHub
UMAP.jl/PlotMNIST.ipynb at master · dillondaudert/UMAP.jl · GitHub

In my own code, I’m given a dictionary, and I convert the values of the dictionary to a matrix which is mat, and keys to a vector which is scid.

Right now I got the umap plot. If I want to divide the plot into 4 subplots. In each subplot I can get about 40 points. Then how do I know each point’s scid? Is there a way to get that?
