Corresponding Plotly trace type.
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
public var opacity: Double? -
Sets the trace name.
The trace name appear as the legend item and on hover.
Declaration
Swift
public var name: String? -
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

Assigns extra meta information associated with this trace that can be used in various text attributes.
Attributes such as trace
name, graph, axis and colorbartitle.text, annotationtextrangeselector,updatemenuesandsliderslabeltext all supportmeta. To access the tracemetavalues in an attribute in the same trace, simply use%{meta[i]}whereiis the index or key of themetaitem in question. To access tracemetain layout attributes, use%{data[n[.meta[i]}whereiis the index or key of themetaandnis the trace index. -

public var transforms: [Transform] -
Controls persistence of some user-driven changes to the trace:
constraintrangeinparcoordstraces, as well as someeditable: truemodifications such asnameandcolorbar.title.Defaults to
layout.uirevision. Note that other user-driven trace attribute changes are controlled bylayoutattributes:trace.visibleis controlled bylayout.legend.uirevision,selectedpointsis 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 nouidis provided. So if your app can add/remove traces before the end of thedataarray, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace auidthat stays with it as it moves.Declaration
Swift
public var uiRevision: Anything? -

Declaration
Swift
public var longitude: CoordinateData? -

lon/latpoint in pixels.Increasing the value makes the densitymapbox trace smoother, but less detailed.
Declaration

By default, densitymapbox traces are placed below the first layer of type symbol If set to “, the layer will be inserted above every existing layer.
Declaration
Swift
public var below: String? -
Sets text elements associated with each (lon,lat) pair If a single string, the same string appears over all the data points.
If an array of string, the items are mapped in order to the this trace’s (lon,lat) coordinates. If trace
hoverinfocontains a text flag and hovertext is not set, these elements will be seen in the hover labels.Declaration
Swift
public var text: Data<String>? -
Sets hover text elements associated with each (lon,lat) pair If a single string, the same string appears over all the data points.

hoverinfomust contain a text flag.Declaration
Swift
public var hoverText: Data<String>? -

If
See morenoneorskipare set, no information is displayed upon hovering. But, ifnoneis set, click and hover events are still fired.Declaration
Swift
public struct HoverInfo : OptionSet, Encodable -
Determines which trace information appear on hover.
If
noneorskipare set, no information is displayed upon hovering. But, ifnoneis set, click and hover events are still fired.Declaration
Swift
public var hoverInfo: HoverInfo? -
Template string used for rendering the information that appear on hover box.
Note that this will override
hoverinfo. 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 inhovertemplateare 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) are available. Anything contained in tag<extra>is displayed in the secondary box, for example “{fullData.name} ”. To hide the secondary box completely, use an empty tag<extra></extra>.Declaration

Declaration
Swift
public var showLegend: Bool? -
Determines whether or not the color domain is computed with respect to the input data (here in
z) or the bounds set inzminandzmaxDefaults tofalsewhenzminandzmaxare set by the user.Declaration
Swift
public var zAuto: Bool? -
Sets the lower bound of the color domain.
Value should have the same units as in

zand if set,zminmust be set as well.Declaration

zminand/orzmaxto be equidistant to this point.Value should have the same units as in
z. Has no effect whenzautoisfalse.Declaration
Swift
public var zMiddle: Double? -
Sets the colorscale.
The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example,
[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]. To control the bounds of the colorscale in color space, usezminandzmax. Alternatively,colorscalemay be a palette name string of the following list: Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu,Reds,Blues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,Earth,Electric,Viridis,Cividis.Declaration
Swift
public var colorScale: ColorScale? -
Determines whether the colorscale is a default palette (
autocolorscale: true) or the palette determined bycolorscale.In case
colorscaleis unspecified orautocolorscaleis true, the default palette will be chosen according to whether numbers in thecolorarray are all positive, all negative or mixed.Declaration
Swift
public var autoColorScale: Bool? -
Reverses the color mapping if true.
If true,
zminwill correspond to the last color in the array andzmaxwill correspond to the first color.Declaration
Swift
public var reverseScale: Bool? -
Determines whether or not a colorbar is displayed for this trace.
Declaration

public var showScale: Bool? -
Undocumented
Declaration
Swift
public var colorBar: ColorBar? -
Sets a reference to a shared color axis.
References to these shared color axes are coloraxis, coloraxis2, coloraxis3, etc. Settings for these shared color axes are set in the layout, under
layout.coloraxis,layout.coloraxis2, etc. Note that multiple color scales can be linked to the same color axis.Declaration
Swift
public var colorAxis: ColorAxis -
Sets a reference between this trace’s data coordinates and a mapbox subplot.
If mapbox (the default value), the data refer to
layout.mapbox. If mapbox2, the data refer tolayout.mapbox2, and so on.Declaration
