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.

Declaration
Swift
public static var animatable: Bool { get } -

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.

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. -
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

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

fillon by default, using tonexty (tonextx) iforientationis h (v) and sets the defaultmodeto lines irrespective of point count. You can only stack on a numeric (linear or log) axis.

Swift
public var clipOnAxis: Bool? -
Sets the area to fill with a solid color.
Defaults to none unless this trace is stacked, then it gets tonexty (tonextx) if
orientationis v (h) Use withfillcolorif 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 astackgroupwill only fill to (or be filled to) other traces in the same group. With multiplestackgroups or some traces stacked and some not, if fill-linked traces are not already consecutive, the later ones will be pushed down in the drawing order.Declaration
