omicverse.pl.contour#
- omicverse.pl.contour(ax, adata, groupby, clusters, basis='X_umap', grid_density=100, contour_threshold=0.1, **kwargs)[源代码]#
Overlay a KDE contour for selected clusters on embedding axes.
- 参数:
ax (matplotlib.axes.Axes) – Axis where contour lines are drawn.
adata (AnnData) – AnnData containing embedding coordinates and cluster labels.
groupby (str) – Observation column for cluster filtering.
clusters (list) – Cluster labels to include in contour estimation.
basis (str, default='X_umap') – Embedding key in
adata.obsm.grid_density (int, default=100) – Resolution of contour estimation grid.
contour_threshold (float, default=0.1) – Relative density threshold used for outer contour level.
**kwargs – Additional arguments forwarded to
ax.contour.
- 返回:
Axis with contour overlay.
