Scatter
The scatter trace type encompasses line charts, scatter charts, text charts, and bubble charts.
The data visualized as scatter point or lines is set in x
and y
. Text (appearing either on
the chart or on hover only) is via text
. Bubble charts are achieved by setting marker.size
and/or marker.color
to numerical arrays.
-
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?
-
Determines whether or not an item corresponding to this trace is shown in the legend.
Declaration
Swift
public var showLegend: Bool?
-
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
public var customData: [String]?
-
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
, annotationtext
rangeselector
,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
is the trace index. -
Array containing integer indices of selected points.
Has an effect only for traces that support selections. Note that an empty array means an empty selection where the
unselected
are turned on for all points, whereas, any other non-array values means no selection all where theselected
andunselected
styles have no effect.Declaration
Swift
public var selectedPoints: Anything?

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 the area to fill with a solid color.
Defaults to none unless this trace is stacked, then it gets tonexty (tonextx) if

if not none. tozerox and tozeroy fill to x=0 and y=0 respectively. tonextx and tonexty fill between the endpoints of this trace and the endpoints of the trace before it, connecting those endpoints with straight lines (to make a stacked area graph); if there is no trace before it, they behave like tozerox and tozeroy. toself connects the endpoints of the trace (or each segment of the trace if it has gaps) into a closed shape. tonext fills the space between two traces if one completely encloses the other (eg consecutive contour lines), and behaves like toself if there is no trace before it. tonext should not be used if one trace does not enclose the other. Traces in astackgroup
will only fill to (or be filled to) other traces in the same group. With multiplestackgroup
