Volume
Draws volume trace between iso-min and iso-max values with coordinates given by four
1-dimensional arrays containing the value
, x
, y
and z
of every vertex of a uniform or
non-uniform 3-D grid.
Horizontal or vertical slices, caps as well as spaceframe between iso-min and iso-max values could also be drawn using this trace.

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

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 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

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. -

Controls persistence of some user-driven changes to the trace:

inparcoords
traces, as well as someeditable: true
modifications such asname

.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

. 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.

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 the opacity of the surface.
Please note that in the case of using high
opacity
values for example a value greater than or equal to 0.5 on two surfaces (and 0.25 with four surfaces), an overlay of multiple transparent surfaces may not perfectly be sorted in depth by the webgl API. This behavior may be improved in the near future and is subject to change.Declaration
Swift
public var opacity: Double?
-
Sets the opacityscale.
The opacityscale must be an array containing arrays mapping a normalized value to an opacity value. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example,
[[0, 1], [0.5, 0.2], [1, 1]]
means that higher/lower values would have higher opacity values and those in the middle would be more transparent Alternatively,opacityscale
may be a palette name string of the following list: ‘min’, ‘max’, ‘extremes’ and ‘uniform’. The default is ‘uniform’.Declaration
