Scatter

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

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.

    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

  • 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.

    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.

  • Set several scatter traces (on the same subplot) to the same stackgroup in order to add their y values (or their x values if orientation is h).

    If blank or omitted this trace will not be stacked. Stacking also turns fill on by default, using tonexty (tonextx) if orientation is h (v) and sets the default mode to lines irrespective of point count. You can only stack on a numeric (linear or log) axis. Traces in a stackgroup will only fill to (or be filled to) other traces in the same group. With multiple stackgroups 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

    Swift

    public var stackGroup: String?
  • Only relevant when stackgroup is used, and only the first orientation found in the stackgroup will be used - including if visible is legendonly but not if it is false.

  • Only relevant when stackgroup is used, and only the first groupnorm found in the stackgroup will be used - including if visible is legendonly but not if it is false.

    Sets the normalization for the sum of this stackgroup. With fraction, the value of each trace at each location is divided by the sum of all trace values at that location. percent is the same but multiplied by 100 to show percentages. If there are multiple subplots, or multiple stackgroups on one subplot, each will be normalized within its own set.

    Note that this will override textinfo. 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.

    If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace’s (x,y) coordinates. To be seen, trace hoverinfo must contain a text flag.

    Declaration

    Swift

    public var hoverText: Data<String>?
  • Determines the drawing mode for this scatter trace.

    If the provided mode includes text then the text elements appear at the coordinates. Otherwise, the text elements appear on hover. If there are less than 20 points and the trace is not stacked then the default is lines+markers. Otherwise, lines.

    Declaration

    Swift

    public var mode: Mode?

    Note that this will override hoverinfo. 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. Dates are formatted using d3-time-format’s syntax %{variable|d3-time-format}, for example “Day: %{2019-01-01|%A}”. https://github.com/d3/d3-time-format#locale_format for details on the date formatting syntax.

    Declaration

    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 orientation is v (h) Use with fillcolor 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 a stackgroup will only fill to (or be filled to) other traces in the same group. With multiple stackgroups 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
