Sets the trace name. The trace name appears as the legend item and on hover.

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).

Determines whether or not an item corresponding to this trace is shown in the legend.

Sets the reference to a legend to show this trace in. References to these legends are "legend", "legend2", "legend3", etc. Settings for these legends are set in the layout, under `layout.legend`, `layout.legend2`, etc.

Sets the legend rank for this trace. Items and groups with smaller ranks are presented on top/left side while with "reversed" `legend.traceorder` they are on bottom/right side. The default legendrank is 1000, so that you can use ranks less than 1000 to place certain items before all unranked items, and ranks greater than 1000 to go after all unranked items. When having unranked or equal rank items shapes would be displayed after traces i.e. according to their order in data and layout.

Sets the legend group for this trace. Traces and shapes part of the same legend group hide/show at the same time when toggling legend items.

• dtick
  Parent: data[type=contourcarpet].colorbar
  Type: number or categorical coordinate string

  Sets the step in-between ticks on this axis. Use with `tick0`. Must be a positive number, or special strings available to "log" and "date" axes. If the axis `type` is "log", then ticks are set every 10^(n"dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. "log" has several special values; "L<f>", where `f` is a positive number, gives ticks linearly spaced in value (but not position). For example `tick0` = 0.1, `dtick` = "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use "D1" (all digits) or "D2" (only 2 and 5). `tick0` is ignored for "D1" and "D2". If the axis `type` is "date", then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set `dtick` to 86400000.0. "date" also has special values "M<n>" gives ticks spaced by a number of months. `n` must be a positive integer. To set ticks on the 15th of every third month, set `tick0` to "2000-01-15" and `dtick` to "M3". To set ticks every 4 years, set `dtick` to "M48"

    Determines the location of color bar's title with respect to the color bar. Defaults to "top" when `orientation` if "v" and defaults to "right" when `orientation` if "h". Note that the title's location used to be set by the now deprecated `titleside` attribute.

  • text
    Parent: data[type=contourcarpet].colorbar.title
    Type: string

    Sets the title of the color bar. Note that before the existence of `title.text`, the title's contents used to be defined as the `title` attribute itself. This behavior has been deprecated.

• x
  Parent: data[type=contourcarpet].colorbar
  Type: number

  Sets the x position with respect to `xref` of the color bar (in plot fraction). When `xref` is "paper", defaults to 1.02 when `orientation` is "v" and 0.5 when `orientation` is "h". When `xref` is "container", defaults to "1" when `orientation` is "v" and 0.5 when `orientation` is "h". Must be between "0" and "1" if `xref` is "container" and between "-2" and "3" if `xref` is "paper".

• xanchor
  Parent: data[type=contourcarpet].colorbar
  Type: enumerated , one of ( "left" | "center" | "right" )

  Sets this color bar's horizontal position anchor. This anchor binds the `x` position to the "left", "center" or "right" of the color bar. Defaults to "left" when `orientation` is "v" and "center" when `orientation` is "h".

• xpad
  Parent: data[type=contourcarpet].colorbar
  Type: number greater than or equal to 0
  Default: 10

  Sets the amount of padding (in px) along the x direction.

• xref
  Parent: data[type=contourcarpet].colorbar
  Type: enumerated , one of ( "container" | "paper" )
  Default: "paper"

  Sets the container `x` refers to. "container" spans the entire `width` of the plot. "paper" refers to the width of the plotting area only.

• y
  Parent: data[type=contourcarpet].colorbar
  Type: number

  Sets the y position with respect to `yref` of the color bar (in plot fraction). When `yref` is "paper", defaults to 0.5 when `orientation` is "v" and 1.02 when `orientation` is "h". When `yref` is "container", defaults to 0.5 when `orientation` is "v" and 1 when `orientation` is "h". Must be between "0" and "1" if `yref` is "container" and between "-2" and "3" if `yref` is "paper".

• yanchor
  Parent: data[type=contourcarpet].colorbar
  Type: enumerated , one of ( "top" | "middle" | "bottom" )

  Sets this color bar's vertical position anchor This anchor binds the `y` position to the "top", "middle" or "bottom" of the color bar. Defaults to "middle" when `orientation` is "v" and "bottom" when `orientation` is "h".

• ypad
  Parent: data[type=contourcarpet].colorbar
  Type: number greater than or equal to 0
  Default: 10

  Sets the amount of padding (in px) along the y direction.

• yref
  Parent: data[type=contourcarpet].colorbar
  Type: enumerated , one of ( "container" | "paper" )
  Default: "paper"

  Sets the container `y` refers to. "container" spans the entire `height` of the plot. "paper" refers to the height of the plotting area only.

Determines whether the colorscale is a default palette (`autocolorscale: true`) or the palette determined by `colorscale`. In case `colorscale` is unspecified or `autocolorscale` is true, the default palette will be chosen according to whether numbers in the `color` array are all positive, all negative or mixed.

Sets the colorscale. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in color space, use `zmin` and `zmax`. Alternatively, `colorscale` may be a palette name string of the following list: Blackbody,Bluered,Blues,Cividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd.

Determines whether or not a colorbar is displayed for this trace.

Reverses the color mapping if true. If true, `zmin` will correspond to the last color in the array and `zmax` will correspond to the first color.

Determines whether or not the color domain is computed with respect to the input data (here in `z`) or the bounds set in `zmin` and `zmax` Defaults to `false` when `zmin` and `zmax` are set by the user.

Sets the upper bound of the color domain. Value should have the same units as in `z` and if set, `zmin` must be set as well.

Sets the mid-point of the color domain by scaling `zmin` and/or `zmax` to be equidistant to this point. Value should have the same units as in `z`. Has no effect when `zauto` is `false`.

Sets the lower bound of the color domain. Value should have the same units as in `z` and if set, `zmax` must be set as well.

Determines whether or not the contour level attributes are picked by an algorithm. If "true", the number of contour levels can be set in `ncontours`. If "false", set the contour level attributes in `contours`.

• coloring
  Parent: data[type=contourcarpet].contours
  Type: enumerated , one of ( "fill" | "lines" | "none" )
  Default: "fill"

  Determines the coloring method showing the contour values. If "fill", coloring is done evenly between each contour level If "lines", coloring is done on the contour lines. If "none", no coloring is applied on this trace.

• end

  Type: number

  Sets the end contour level value. Must be more than `contours.start`

• labelfont
  Parent: data[type=contourcarpet].contours
  Type: object containing one or more of the keys listed below.

  Sets the font used for labeling the contour levels. The default color comes from the lines, if shown. The default family and size come from `layout.font`.

    Type: color
  • family
    Parent: data[type=contourcarpet].contours.labelfont
    Type: string

    HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans", "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".

  • lineposition
    Parent: data[type=contourcarpet].contours.labelfont
    Type: flaglist string. Any combination of "under", "over", "through" joined with a "+" OR "none".
    Examples: "under", "over", "under+over", "under+over+through", "none"
    Default: "none"

    Sets the kind of decoration line(s) with text, such as an "under", "over" or "through" as well as combinations e.g. "under+over", etc.

  • shadow
    Parent: data[type=contourcarpet].contours.labelfont
    Type: string
    Default: "none"

    Sets the shape and color of the shadow behind text. "auto" places minimal shadow and applies contrast text font color. See https://developer.mozilla.org/en-US/docs/Web/CSS/text-shadow for additional options.

  • size
    Parent: data[type=contourcarpet].contours.labelfont
    Type: number greater than or equal to 1

    Default: "normal"

    Sets whether a font should be styled with a normal or italic face from its family.

  • textcase
    Parent: data[type=contourcarpet].contours.labelfont
    Type: enumerated , one of ( "normal" | "word caps" | "upper" | "lower" )
    Default: "normal"

    Sets capitalization of text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.

  • variant
    Parent: data[type=contourcarpet].contours.labelfont
    Type: enumerated , one of ( "normal" | "small-caps" | "all-small-caps" | "all-petite-caps" | "petite-caps" | "unicase" )
    Default: "normal"

    Sets the variant of the font.

  • weight
    Parent: data[type=contourcarpet].contours.labelfont
    Type: integer between or equal to 1 and 1000
    Default: normal

    Sets the weight (or boldness) of the font.

• labelformat
  Parent: data[type=contourcarpet].contours
  Type: string
  Default: ""

  Sets the contour label formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format.

• operation
  Parent: data[type=contourcarpet].contours
  Type: enumerated , one of ( "=" | "<" | ">=" | ">" | "<=" | "[]" | "()" | "[)" | "(]" | "][" | ")(" | "](" | ")[" )
  Default: "="

  Sets the constraint operation. "=" keeps regions equal to `value` "<" and "<=" keep regions less than `value` ">" and ">=" keep regions greater than `value` "[]", "()", "[)", and "(]" keep regions inside `value[0]` to `value[1]` "][", ")(", "](", ")[" keep regions outside `value[0]` to value[1]` Open vs. closed intervals make no difference to constraint display, but all versions are allowed for consistency with filter transforms.

• showlabels
  Parent: data[type=contourcarpet].contours
  Type: boolean

  Determines whether to label the contour lines with their values.

• showlines
  Parent: data[type=contourcarpet].contours
  Type: boolean
  Default: true

  Determines whether or not the contour lines are drawn. Has an effect only if `contours.coloring` is set to "fill".

• size
  Parent: data[type=contourcarpet].contours
  Type: number greater than or equal to 0

  Sets the step between each contour level. Must be positive.

• start
  Parent: data[type=contourcarpet].contours
  Type: number

  Sets the starting contour level value. Must be less than `contours.end`

• type
  Parent: data[type=contourcarpet].contours
  Type: enumerated , one of ( "levels" | "constraint" )
  Default: "levels"

  If `levels`, the data is represented as a contour plot with multiple levels displayed. If `constraint`, the data is represented as constraints with the invalid region shaded as specified by the `operation` and `value` parameters.

• value
  Parent: data[type=contourcarpet].contours
  Type: number or categorical coordinate string
  Default: 0

  Sets the value or values of the constraint boundary. When `operation` is set to one of the comparison values (=,<,>=,>,<=) "value" is expected to be a number. When `operation` is set to one of the interval values ([],(),[),(],][,)(,](,)[) "value" is expected to be an array of two numbers where the first is the lower bound and the second is the upper bound.

Sets the fill color if `contours.type` is "constraint". Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available.

Sets the maximum number of contour levels. The actual number of contours will be chosen automatically to be less than or equal to the value of `ncontours`. Has an effect only if `autocontour` is "true" or if `contours.size` is missing.

Transposes the z data.

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.
