, groups=None, n_genes=10, groupby=None, key=None, show=None, save=None, **kwds)

Plot ranking of genes using heatmap plot (see heatmap())

adata : AnnDataAnnData

Annotated data matrix.

groups : str, Sequence[str], NoneUnion[str, Sequence[str], None] (default: None)

The groups for which to show the gene ranking.

n_genes : intint (default: 10)

Number of genes to show.

groupby : str, NoneOptional[str] (default: None)

The key of the observation grouping to consider. By default, the groupby is chosen from the rank genes groups parameter but other groupby options can be used. It is expected that groupby is a categorical. If groupby is not a categorical observation, it would be subdivided into num_categories (see heatmap()).

key : str, NoneOptional[str] (default: None)

Key used to store the ranking results in adata.uns.


Are passed to heatmap().

show : bool, NoneOptional[bool] (default: None)

Show the plot, do not return axis.

save : bool, NoneOptional[bool] (default: None)

If True or a str, save the figure. A string is appended to the default filename. Infer the filetype if ending on {'.pdf', '.png', '.svg'}.


A matplotlib axes object. Only works if plotting a single component.
