Declaration
Swift
public let type: String
-
Switch indicating whether the trace supports animation of its data.
Declaration
Swift
public static var animatable: Bool { get }
-
Determines whether or not this trace is visible.
If legendonly, the trace is not drawn, but can appear as a legend item (provided that the legend itself is visible).
Declaration
Swift
public var visible: Visible?
-
Sets the legend group for this trace.
Traces part of the same legend group hide/show at the same time when toggling legend items.
Declaration
Swift
public var legendGroup: String?

Sets the opacity of the trace.
Declaration
Swift

Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.
Declaration
Swift
public var uid: String?
-
Assigns id labels to each datum.
These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.
Declaration
Swift
public var ids: [String]?
-
Assigns extra data each datum.
This may be useful when listening to hover, click and selection events. Note that, scatter traces also appends customdata items in the markers DOM elements
Declaration
Swift

Attributes such as trace
name
, graph, axis and colorbartitle.text

,updatemenues
andsliders
label
text all supportmeta
. To access the tracemeta
values in an attribute in the same trace, simply use%{meta[i]}
wherei
is the index or key of themeta
item in question. To access tracemeta
in layout attributes, use%{data[n[.meta[i]}
wherei
is the index or key of themeta
andn

public var transforms: [Transform]
-
Controls persistence of some user-driven changes to the trace:
constraintrange
inparcoords
traces, as well as someeditable: true
modifications such asname
andcolorbar.title
.Defaults to
layout.uirevision
. Note that other user-driven trace attribute changes are controlled bylayout
attributes:trace.visible
is controlled bylayout.legend.uirevision
,selectedpoints
is controlled bylayout.selectionrevision
, andcolorbar.(x|y)
(accessible withconfig: {editable: true}
) is controlled bylayout.editrevision
. Trace changes are tracked byuid
, which only falls back on trace index if nouid
is provided. So if your app can add/remove traces before the end of thedata
array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace auid
that stays with it as it moves.Declaration

-
Sets text elements associated with each (lon,lat) pair If a single string, the same string appears over all the data points.

. Variables are inserted using %{variable}, for example “y: %{y}”. Numbers are formatted using d3-format’s syntax %{variable:d3-format}, for example “Price: %{y:$.2f}”. https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format for details on the formatting syntax. Dates are formatted using d3-time-format’s syntax %{variable|d3-time-format}, for example “Day: %{2019-01-01|%A}”. https://github.com/d3/d3-time-format#locale_format for details on the date formatting syntax. The variables available inhovertemplate
are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that arearrayOk: true
