The AnnData has the reference to the individual files in the .obs annotations:

Let us create a plot:
markers = bt.CellMarker.lookup()
import scanpy as sc
sc.pp.pca(adata)
sc.pl.pca(adata, color=markers.cd8.name, save="_cd8")

WARNING: saving figure to file figures/pca_cd8.pdf
artifact = ln.Artifact("./figures/pca_cd8.pdf", description="My result on CD8").save()
artifact.view_lineage()
Given the image is part of the notebook, there isn’t an actual need to save it and you can also rely on the report that you’ll create when saving the notebook:
ln.finish()
# clean up test instance
!rm -r test-flow
!lamin delete --force test-facs
Show code cell output
rm: cannot remove 'test-flow': No such file or directory
