Aesthetics Reference

Use this page when you want the fastest route to track fields and styling options without reading source.

Every track exposes three groups of fields:

• track: constructor-level fields such as title, height, autoscale_group, and color_group
• aesthetics: visual controls such as style, color, alpha, min_value, and max_value
• label: title and scale annotation controls such as plot_scale, title_location, and scale_location

Discover fields at runtime

from plotnado import GenomicFigure, BigWigTrack, list_options

GenomicFigure.track_options("bigwig")
GenomicFigure.track_options("overlay")
GenomicFigure.track_options_markdown("genes")

BigWigTrack.options()
BigWigTrack.options_markdown()
list_options(BigWigTrack)

High-value fields by category

Category	Common fields	Notes
Track	title, height, autoscale_group, color_group	These apply to the whole track panel
Aesthetics	color, alpha, style, min_value, max_value	These affect how the track is drawn
Label	plot_title, plot_scale, title_location, scale_location	These control title and scale text

Overlay-specific guidance

Overlay tracks are scaled as a single panel.

• autoscale_group belongs on the overlay itself when the whole panel should match sibling signal tracks.
• Explicit overlay min_value / max_value overrides grouped or global autoscale on that edge.
• show_labels=False is useful when the overlay is dense and the panel title carries enough meaning.
