Create a basic Gosling Track.

Although it is possible to set all Track properties as constructor attributes, it is more idiomatic to use methods such as mark_point(), encode(), transform_filter(), properties(), etc.

Attributes:

dataDataDeep

markMark

_assignedHeightfloat

_assignedWidthfloat

Internal: Used for responsive spec

_invalidTrackboolean

_renderingIdstring

internal

assemblyAssembly

A string that specifies the genome builds to use. Currently support “hg38”, “hg19”, “hg18”, “hg17”, “hg16”, “mm10”, “mm9”, and “unknown”.

__Note:__: with “unknown” assembly, genomic axes do not show chrN: in labels.

baselineYfloat

centerRadiusfloat

Proportion of the radius of the center white space.

__Default:__ 0.3

coloranyOf(Color, ChannelValue)

dataTransformList(DataTransform)

displacementDisplacement

endAnglefloat

Specify the end angle (in the range of [0, 360]) of circular tracks ({“layout”: “circular”}).

experimentalMapping(required=[])

flipYboolean

heightfloat

Specify the track height in pixels.

idstring

Assigned to uid in a HiGlass view config, used for API and caching.

innerRadiusfloat

Specify the inner radius of tracks when ({“layout”: “circular”}).

layoutLayout

Specify the layout type of all tracks.

linkingIdstring

Specify an ID for [linking multiple views](http://gosling-lang.org/docs/user-interaction#linking-views)

opacityanyOf(Opacity, ChannelValue)

orientationOrientation

Specify the orientation.

outerRadiusfloat

Specify the outer radius of tracks when {“layout”: “circular”}.

overlayOnPreviousTrackboolean

overrideTemplateboolean

prereleaseMapping(required=[])

internal

rowanyOf(Row, ChannelValue)

sizeanyOf(Size, ChannelValue)

spacingfloat

The size of the gap (1) between tracks, (2) between views, and (3) of the origin of circular tracks. The effect of this property depends on where on the spec you specify the spacing.

In a linear layout, this value is used in pixels, while in a circular layout, this value is used relative to the height of the tracks or views.

startAnglefloat

Specify the start angle (in the range of [0, 360]) of circular tracks ({“layout”: “circular”}).

staticboolean

Whether to disable [Zooming and Panning](http://gosling-lang.org/docs/user-interaction#zooming-and-panning), __Default:__ false.

stretchboolean

strokeanyOf(Stroke, ChannelValue)

strokeWidthanyOf(StrokeWidth, ChannelValue)

styleStyle

Define the [style](http://gosling-lang.org/docs/visual-channel#style-related-properties) of multive views. Will be overwritten by the style of children elements (e.g., view, track).

subtitlestring

textanyOf(Text, ChannelValue)

titlestring

If defined, will show the textual label on the left-top corner of a track.

tooltipList(Tooltip)

visibilityList(VisibilityCondition)

widthfloat

Specify the track width in pixels.

xanyOf(X, ChannelValue)

x1anyOf(X, ChannelValue)
