Distance distributions as box plots, one box per target cell type.

The heatmap shows means; this shows the spread behind them, which is where bimodality and long tails become visible. Built by melting the per-cell distance table into long form.

Parameters:

Name	Type	Description	Default
`data`	`(AnnData \| SpatialData \| str, required)`	The cell table. An `AnnData`, a path to an `.h5ad` file, a `SpatialData` object, or a path to a `.zarr` SpatialData store.	required
`spatialDistance`	`str`	Key in `uns` holding the distance table.	`'spatial_distance'`
`phenotype`	`str`	Column in `obs` holding the source cell types.	`'phenotype'`
`imageId`	`str`	Column in `obs` holding image identifiers.	`'imageid'`
`distanceFrom`	`str \| list`	Keep only cells of these phenotypes — the cell types you measure from.	`None`
`distanceTo`	`str \| list`	Keep only these target columns — the cell types you measure to.	`None`
`xAxis`	`str`	Accepted for signature compatibility with scimap; the x axis is always the target cell type.	`None`
`yAxis`	`str`	Accepted for signature compatibility with scimap; the y axis is always distance.	`None`
`facetBy`	`str`	Accepted for signature compatibility with scimap; the current implementation draws a single panel. Use `subsetCol` and `subsetValue` to plot one facet at a time.	`None`
`plotType`	`str`	Accepted for signature compatibility with scimap; box plots are drawn.	`None`
`subsetCol`	`str`	Column in `obs` to filter on before plotting.	`None`
`subsetValue`	`str \| list`	Values of `subsetCol` to keep.	`None`
`**kwargs`	`dict`	Extra options. `figsize` sets the figure size in inches.	`{}`
`fileName`	`str`	File name for the saved figure. The extension decides the format.	`'spatial_distance_distribution.pdf'`
`outputDir`	`str`	Directory to save the figure in. When `None` nothing is written.	`None`
`saveDir`	`str`	Deprecated alias for `outputDir`, kept for scripts carried over from scimap. `outputDir` wins when both are given.	`None`
`show`	`bool`	Call `plt.show()` before returning. Set `False` in scripts and notebooks that save rather than display.	`True`
`returnData`	`bool`	Return the `DataFrame` behind the plot instead of drawing it.	`False`
`returnFig`	`bool`	Return `(fig, axes)`. With `returnData` as well, returns `(fig, axes, plotData)`.	`False`
`dpi`	`int`	Resolution of the saved figure.	`300`
`transparent`	`bool`	Save with a transparent background.	`False`
`sdataTable`	`str`	Which `SpatialData` table to read. Ignored for `AnnData` input, and optional when the store has exactly one table.	`None`

Returns:

Name	Type	Description
`result`	`None \| DataFrame \| tuple`	`None` by default; the long-form `DataFrame` (`phenotype`, image id, `distanceTo`, `distance`) with `returnData=True`; `(fig, ax)` with `returnFig=True`.

Example

adata = sp.tl.spatialDistance(adata, phenotype="phenotype")
sp.pl.spatialDistanceDistribution(adata, distanceFrom="Treg")
