Surface

public struct Surface<ZSurfaceData, XYData> : Trace, SceneSubplot where ZSurfaceData : Plotable, XYData : Plotable

The data the describes the coordinates of the surface is set in z.

Data in z should be a {2D array}. Coordinates in x and y can either be 1D {arrays} or {2D arrays} (e.g. to graph parametric surfaces). If not provided in x and y, the x and y coordinates are assumed to be linear starting at 0 with a unit step. The color scale corresponds to the z values by default. For custom color scales, use surfacecolor which should be a {2D array}, where its bounds can be controlled using cmin and cmax.

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 stream: Stream?
  • 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.

  • 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.
