For making UMAP plots, please use Scanpy PlotEmbed with the output of this tool and enter "umap" as the name of the embedding to plot.
UMAP (Uniform Manifold Approximation and Projection) is a manifold learning technique suitable for visualizing high-dimensional data. Besides tending to be faster than tSNE, it optimizes the embedding such that it best reflects the topology of the data, which we represent throughout Scanpy using a neighborhood graph. tSNE, by contrast, optimizes the distribution of nearest-neighbor distances in the embedding such that these best match the distribution of distances in the high-dimensional space. We use the implementation of umap-learn (McInnes et al, 2018). For a few comparisons of UMAP with tSNE, see this preprint.
It yields X_umap, UMAP coordinates of data.

Version history 1.9.301+galaxy0: Moves to Scanpy 1.9.3
1.8.1+galaxy9: Fixes version label to get versions sorted properly on Galaxy (equivalent to 1.8.1+3+galaxy0). In addition, adds ability to make fields unique in AnnData operations, adds additional handler on Scrubblet for workflows convenience, enables Scanpy tools to avoid outputing AnnData/matrix files when not required.
1.8.1+3+galaxy0: Upate to scanpy-scripts 1.1.3 (running scanpy ==1.8.1), including a fix to MTX output and a bugfix for the Scrublet wrapper.
1.8.1+2+galaxy0: Upate to scanpy-scripts 1.1.2 (running scanpy ==1.8.1), including improved boolean handling for mito etc.
1.8.1+1+galaxy0: Upate to scanpy-scripts 1.1.1 build 1 (running scanpy ==1.8.1), including improved Scrublet integration with batch handling.
1.8.1+galaxy0: Upate to scanpy-scripts 1.0.1 (running scanpy ==1.8.1), including Scrublet integration.
1.7.2+galaxy0: Upate to scanpy-scripts 0.3.3 (running scanpy ==1.7.2) to incorporate fix for object output from PAGA plotting, to allow PAGA init of FDG.
1.6.0+galaxy0: Update to scanpy-scripts 0.2.13 (running scanpy ==1.6.0) to incorporate new options, code simplifications, and batch integration methods. Jonathan Manning, Expression Atlas team https://www.ebi.ac.uk/gxa/home at EMBL-EBI https://www.ebi.ac.uk/
1.4.3+galaxy10: Update to scanpy-scripts 0.2.10 (running scanpy ==1.4.3) to address bugfixes in run-pca.
1.4.3+galaxy10: Update to scanpy-scripts 0.2.9 (running scanpy ==1.4.3) to address bugfixes in find-variable-genes.
1.4.3+galaxy10: Use profile 18.01 for modules.
1.4.3+galaxy6: Update to scanpy-scripts 0.2.8 (running scanpy ==1.4.3) and wider compatibility with other Galaxy modules. Bug fixes in filtering and plotting improvements.
1.4.3+galaxy0: Update to scanpy-scripts 0.2.5 (running scanpy ==1.4.3).
1.4.2+galaxy0: Update to scanpy-scripts 0.2.4 (requires scanpy >=1.4.2).
1.3.2+galaxy1: Normalise-data and filter-genes: Exposes ability to output 10x files.
1.3.2+galaxy0: Initial contribution. Ni Huang and Pablo Moreno, Expression Atlas team https://www.ebi.ac.uk/gxa/home at EMBL-EBI https://www.ebi.ac.uk/ and Teichmann Lab at Wellcome Sanger Institute.
