Gene expression and annotation changes along paths in the abstracted graph.

adata : AnnData

An annotated data matrix.

nodes : list of group names or their category indices

A path through nodes of the abstracted graph, that is, names or indices (within .categories) of groups that have been used to run PAGA.

keys : list of str

Either variables in adata.var_names or annotations in adata.obs. They are plotted using color_map.

use_raw : bool, optional (default: True)

Use adata.raw for retrieving gene expressions if it has been set.

annotations : list of annotations, optional (default: ['dpt_pseudotime'])

Plot these keys with color_maps_annotations. Need to be keys for adata.obs.

color_map : color map for plotting keys or None, optional (default: None)

Matplotlib colormap.

color_maps_annotations : dict storing color maps or None, optional (default: {‘dpt_pseudotime’: ‘Greys’})

Color maps for plotting the annotations. Keys of the dictionary must appear in annotations.

palette_groups : list of colors or None, optional (default: None)

Ususally, use the same as used for coloring the abstracted graph.

n_avg : int, optional (default: 1)

Number of data points to include in computation of running average.

groups_key : str, optional (default: None)

Key of the grouping used to run PAGA. If None, defaults to adata.uns['paga']['groups'].

as_heatmap : bool, optional (default: True)

Plot the timeseries as heatmap. If not plotting as heatmap, annotations have no effect.

show_node_names : bool, optional (default: True)

Plot the node names on the nodes bar.

show_colorbar : bool, optional (default: True)

Show the colorbar.

show_yticks : bool, optional (default: True)

Show the y ticks.

normalize_to_zero_one : bool, optional (default: True)

Shift and scale the running average to [0, 1] per gene.

return_data : bool, optional (default: False)

Return the timeseries data in addition to the axes if True.

show : bool, optional (default: None)

Show the plot, do not return axis.

save : bool or str, optional (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’}.

ax : Axes

A matplotlib axes object.

Return type

Axes, NoneOptional[Axes]


A Axes object, if ax is None, else None. If return_data, return the timeseries data in addition to an axes.
