Bar

public struct Bar<XData, YData> : Trace, XYSubplot where XData : Plotable, YData : Plotable

The data visualized by the span of the bars is set in y if orientation is set th v (the default) and the labels are set in x.

By setting orientation to h, the roles are interchanged.

    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>?
  • 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 the selected and unselected styles have no effect.

  • 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.
