    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 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?
  • uid

    Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.

    Declaration

    Swift

    public var uid: String?
  • ids

    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 colorbar title.text, annotation text rangeselector, updatemenues and sliders label text all support meta. To access the trace meta values in an attribute in the same trace, simply use %{meta[i]} where i is the index or key of the meta item in question. To access trace meta in layout attributes, use %{data[n[.meta[i]} where i is the index or key of the meta and n is the trace index.

    Declaration

    Swift

    public var meta: Data<Anything>?

  • Undocumented

    Declaration

    Declaration

    public var stream: Stream?
  • Undocumented

    Declaration

    Swift

    public var transforms: [Transform]
  • Controls persistence of some user-driven changes to the trace: constraintrange in parcoords traces, as well as some editable: true modifications such as name and colorbar.title.

    Defaults to layout.uirevision. Note that other user-driven trace attribute changes are controlled by layout attributes: trace.visible is controlled by layout.legend.uirevision, selectedpoints is controlled by layout.selectionrevision, and colorbar.(x|y) (accessible with config: {editable: true}) is controlled by layout.editrevision. Trace changes are tracked by uid, which only falls back on trace index if no uid is provided. So if your app can add/remove traces before the end of the data array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace a uid that stays with it as it moves.
