• automargin
  Parent: layout.title
  Type: boolean

  Determines whether the title can automatically push the figure margins. If `yref='paper'` then the margin will expand to ensure that the title doesn’t overlap with the edges of the container. If `yref='container'` then the margins will ensure that the title doesn’t overlap with the plot area, tick labels, and axis titles. If `automargin=true` and the margins need to be expanded, then y will be set to a default 1 and yanchor will be set to an appropriate default to ensure that minimal margin space is needed. Note that when `yref='paper'`, only 1 or 0 are allowed y values. Invalid values will be reset to the default 1.

Sets the background color of the paper where the graph is drawn.

Sets the background color of the plotting area in-between x and y axes.

Using "strict" a numeric string in trace data is not converted to a number. Using "convert types" a numeric string in trace data may be treated as a number during automatic axis `type` detection. This is the default value; however it could be overridden for individual axes.

• diverging
  Parent: layout.colorscale
  Type: colorscale
  Default: [[0, rgb(5,10,172)], [0.35, rgb(106,137,247)], [0.5, rgb(190,190,190)], [0.6, rgb(220,170,132)], [0.7, rgb(230,145,90)], [1, rgb(178,10,28)], ]

• uirevision
  Parent: layout.modebar
  Type: number or categorical coordinate string

  Controls persistence of user-driven changes related to the modebar, including `hovermode`, `dragmode`, and `showspikes` at both the root level and inside subplots. Defaults to `layout.uirevision`.

Determines the mode of hover interactions. If "closest", a single hoverlabel will appear for the "closest" point within the `hoverdistance`. If "x" (or "y"), multiple hoverlabels will appear for multiple points at the "closest" x- (or y-) coordinate within the `hoverdistance`, with the caveat that no more than one hoverlabel will appear per trace. If "x unified" (or "y unified"), a single hoverlabel will appear multiple points at the closest x- (or y-) coordinate within the `hoverdistance` with the caveat that no more than one hoverlabel will appear per trace. In this mode, spikelines are enabled by default perpendicular to the specified axis. If false, hover interactions are disabled.

Determines the mode of single click interactions. "event" is the default value and emits the `plotly_click` event. In addition this mode emits the `plotly_selected` event in drag modes "lasso" and "select", but with no event data attached (kept for compatibility reasons). The "select" flag enables selecting single data points via click. This mode also supports persistent selections, meaning that pressing Shift while clicking, adds to / subtracts from an existing selection. "select" with `hovermode`: "x" can be confusing, consider explicitly setting `hovermode`: "closest" when using this feature. Selection events are sent accordingly as long as "event" flag is set as well. When the "event" flag is missing, `plotly_click` and `plotly_selected` events are not fired.

Determines the mode of drag interactions. "select" and "lasso" apply only to scatter traces with markers or text. "orbit" and "turntable" apply only to 3D scenes.

When `dragmode` is set to "select", this limits the selection of the drag to horizontal, vertical or diagonal. "h" only allows horizontal selection, "v" only vertical, "d" only diagonal and "any" sets no limit.

    Type: string
    Default: "dot"

    Sets the dash style of lines. Set to a dash type string ("solid", "dot", "dash", "longdash", "dashdot", or "longdashdot") or a dash length list in px (eg "5px,10px,2px,2px").

  • width
    Parent: layout.newselection.line
    Type: number greater than or equal to 1
    Default: 1

    Sets the line width (in px).

• mode
  Parent: layout.newselection
  Type: enumerated , one of ( "immediate" | "gradual" )
  Default: "immediate"

  Describes how a new selection is created. If `immediate`, a new selection is created after first mouse up. If `gradual`, a new selection is not created after first mouse. By adding to and subtracting from the initial selection, this option allows declaring extra outlines of the selection.

Sets the default distance (in pixels) to look for data to add hover labels (-1 means no cutoff, 0 means no looking for data). This is only a real distance for hovering on point-like objects, like scatter points. For area-like objects (bars, scatter fills, etc) hovering is on inside the area and off outside, but these objects will not supersede hover on point-like objects in case of conflict.

Sets the default distance (in pixels) to look for data to draw spikelines to (-1 means no cutoff, 0 means no looking for data). As with hoverdistance, distance does not apply to area-like objects. In addition, some objects can be hovered on but will not generate spikelines, such as scatter fills.

  Default: "cubic-in-out"

  The easing function used for the transition

• ordering
  Parent: layout.transition
  Type: enumerated , one of ( "layout first" | "traces first" )
  Default: "layout first"

  Determines whether the figure's layout or traces smoothly transitions during updates that make both traces and layout change.

If provided, a changed value tells `Plotly.react` that one or more data arrays has changed. This way you can modify arrays in-place rather than making a complete new copy for an incremental change. If NOT provided, `Plotly.react` assumes that data arrays are being treated as immutable, thus any data array with a different identity from its predecessor contains new data.

Used to allow user interactions with the plot to persist after `Plotly.react` calls that are unaware of these interactions. If `uirevision` is omitted, or if it is given and it changed from the previous `Plotly.react` call, the exact new figure is used. If `uirevision` is truthy and did NOT change, any attribute that has been affected by user interactions and did not receive a different value in the new figure will keep the interaction value. `layout.uirevision` attribute serves as the default for `uirevision` attributes in various sub-containers. For finer control you can set these sub-attributes directly. For example, if your app separately controls the data on the x and y axes you might set `xaxis.uirevision="time"` and `yaxis.uirevision="cost"`. Then if only the y data is changed, you can update `yaxis.uirevision="quantity"` and the y axis range will reset but the x axis range will retain any user-driven zoom.

Controls persistence of user-driven changes in `editable: true` configuration, other than trace names and axis titles. Defaults to `layout.uirevision`.

Controls persistence of user-driven changes in selected points from all traces.

Default attributes to be applied to the plot. Templates can be created from existing plots using `Plotly.makeTemplate`, or created manually. They should be objects with format: `{layout: layoutTemplate, data: {[type]: [traceTemplate, ...]}, ...}` `layoutTemplate` and `traceTemplate` are objects matching the attribute structure of `layout` and a data trace. Trace templates are applied cyclically to traces of each type. Container arrays (eg `annotations`) have special handling: An object ending in `defaults` (eg `annotationdefaults`) is applied to each array item. But if an item has a `templateitemname` key we look in the template array for an item with matching `name` and apply that instead. If no matching `name` is found we mark the item invisible. Any named template item not referenced is appended to the end of the array, so you can use this for a watermark annotation or a logo image, for example. To omit one of these items on the plot, make an item with matching `templateitemname` and `visible: false`.

Assigns extra meta information that can be used in various `text` attributes. Attributes such as the graph, axis and colorbar `title.text`, annotation `text` `trace.name` in legend items, `rangeselector`, `updatemenus` and `sliders` `label` text all support `meta`. One can access `meta` fields using template strings: `%{meta[i]}` where `i` is the index of the `meta` item in question. `meta` can also be an object for example `{key: value}` which can be accessed %{meta[key]}.

Placeholder for exporting automargin-impacting values namely `margin.t`, `margin.b`, `margin.l` and `margin.r` in "full-json" mode.

• columns
  Parent: layout.grid
  Type: integer greater than or equal to 1

  The number of columns in the grid. If you provide a 2D `subplots` array, the length of its longest row is used as the default. If you give an `xaxes` array, its length is used as the default. But it's also possible to have a different length, if you want to leave a row at the end for non-cartesian subplots.

  If no `subplots`, `xaxes`, or `yaxes` are given but we do have `rows` and `columns`, we can generate defaults using consecutive axis IDs, in two ways: "coupled" gives one x axis per column and one y axis per row. "independent" uses a new xy pair for each cell, left-to-right across each row then iterating rows according to `roworder`.

• roworder
  Parent: layout.grid
  Type: enumerated , one of ( "top to bottom" | "bottom to top" )
  Default: "top to bottom"

  Is the first row the top or the bottom? Note that columns are always enumerated from left to right.

• rows
  Parent: layout.grid
  Type: integer greater than or equal to 1

  The number of rows in the grid. If you provide a 2D `subplots` array or a `yaxes` array, its length is used as the default. But it's also possible to have a different length, if you want to leave a row at the end for non-cartesian subplots.

• subplots
  Parent: layout.grid
  Type: array

  Used for freeform grids, where some axes may be shared across subplots but others are not. Each entry should be a cartesian subplot id, like "xy" or "x3y2", or "" to leave that cell empty.

• drawdirection
  Parent: layout.newshape
  Type: enumerated , one of ( "ortho" | "horizontal" | "vertical" | "diagonal" )
  Default: "diagonal"

  When `dragmode` is set to "drawrect", "drawline" or "drawcircle" this limits the drag to be horizontal, vertical or diagonal. Using "diagonal" there is no limit e.g. in drawing lines in any direction. "ortho" limits the draw to be either horizontal or vertical. "horizontal" allows horizontal extend. "vertical" allows vertical extend.

• fillcolor
  Parent: layout.newshape
  Type: color
  Default: "rgba(0,0,0,0)"

  Sets the selection's x coordinate axis. If set to a x axis id (e.g. "x" or "x2"), the `x` position refers to a x coordinate. If set to "paper", the `x` position refers to the distance from the left of the plotting area in normalized coordinates where "0" ("1") corresponds to the left (right). If set to a x axis ID followed by "domain" (separated by a space), the position behaves like for "paper", but refers to the distance in fractions of the domain length from the left of the domain of that axis: e.g., "x2 domain" refers to the domain of the second x axis and a x position of 0.5 refers to the point between the left and the right of the domain of the second x axis.

If set to "paper", the `y` position refers to the distance from the bottom of the plotting area in normalized coordinates where "0" ("1") corresponds to the bottom (top). If set to a y axis ID followed by "domain" (separated by a space), the position behaves like for "paper", but refers to the distance in fractions of the domain length from the bottom of the domain of that axis: e.g., "y2 domain" refers to the domain of the second y axis and a y position of 0.5 refers to the point between the bottom and the top of the domain of the second y axis.
