Color & layers¶

Switch the color panel between category, genes and embed; the map recolors to match.

import milume
w = milume.peek(adata, color="cell_type", genes=["GeneA", "GeneB", "GeneC"])
w.active_category, w.active_genes

Color tabs¶

The right panel has three pill tabs. They have no icons, so the table names each tab.

	Tab	What it colors by
1	category	An `obs` category column. Expand it () to toggle single subcategories.
2	genes	Expression of the picked genes, with ridgeline densities and a blend legend. Pick genes in the field under the legend.
3	embed	An embedding (for example `X_pca`) mapped to RGB, with an RGB-cube legend. Choose the embedding from the dropdown.

	Control	What it does
	points/raster	Flip between drawing each cell as a point and aggregating cells into raster bins (). The icon shows the current mode.

The left panel lists every selection and landmark.

	Control	What it does
1	Selections	Click a row to make that selection active.
2	Landmarks	Click a row to select the landmark and open its context toolbar.
	Layer actions	Hide / Show, Rename, Delete.
	Collapse left panel ([)	Hide the list; see Navigate.

w.set_render_mode("raster")       # or "points"
w.category_colors("cell_type")    # {label: hex}, as the map draws it
