JavaScript Figure Reference: contourcarpet Traces

A contourcarpet trace is an object with the key "type" equal to "contourcarpet" (i.e. {"type": "contourcarpet"}) and any of the keys listed below.

Plots contours on either the first carpet axis or the carpet axis with a matching `carpet` attribute. Data `z` is interpreted as matching that of the corresponding carpet axis.

    • tickmode
      Parent: data[type=contourcarpet].colorbar
      Type: enumerated , one of ( "auto" | "linear" | "array" )

      Sets the tick mode for this axis. If "auto", the number of ticks is set via `nticks`. If "linear", the placement of the ticks is determined by a starting position `tick0` and a tick step `dtick` ("linear" is the default value if `tick0` and `dtick` are provided). If "array", the placement of the ticks is set via `tickvals` and the tick text is `ticktext`. ("array" is the default value if `tickvals` is provided).

    • nticks
      Parent: data[type=contourcarpet].colorbar
      Type: integer greater than or equal to 0
      Default: 0

      Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to `nticks`. Has an effect only if `tickmode` is set to "auto".

    • tick0
      Parent: data[type=contourcarpet].colorbar
      Type: number or categorical coordinate string

      Sets the placement of the first tick on this axis. Use with `dtick`. If the axis `type` is "log", then you must take the log of your starting tick (e.g. to set the starting tick to 100, set the `tick0` to 2) except when `dtick`="L<f>" (see `dtick` for more info). If the axis `type` is "date", it should be a date string, like date data. If the axis `type` is "category", it should be a number, using the scale where each category is assigned a serial number from zero in the order it appears.

    • 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"

    • tickvals
      Parent: data[type=contourcarpet].colorbar

        Type: string

        When used in a template, named items are created in the output figure in addition to any items the figure already has in this array. You can modify these items in the output figure by making your own item with `templateitemname` matching this `name` alongside your modifications (including `visible: false` or `enabled: false` to hide it). Has no effect outside of a template.

      • templateitemname
        Parent: data[type=contourcarpet].colorbar.tickformatstops[]

    Parent: data[type=contourcarpet]
    Type: number

    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.

  • zmid
    Parent: data[type=contourcarpet]
    Type: number

    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`.

  • zmin
    Parent: data[type=contourcarpet]
    Type: number

    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.

  • autocontour
    Parent: data[type=contourcarpet]
    Type: boolean
    Default: true

    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`.

  • carpet
    Parent: data[type=contourcarpet]
    Type: string

    The `carpet` of the carpet axes on which this contour trace lies

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

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

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

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

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

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

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

    • 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.

    • 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".

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

      Determines whether to label the contour lines with their values.

    • 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`.

      • 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".

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

      Sets the contour label formatting rule using d3 formatting mini-language which is very similar to Python, see: https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#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.

    • 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.

  • fillcolor
    Parent: data[type=contourcarpet]
    Type: color

    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.

  • ncontours
    Parent: data[type=contourcarpet]
    Type: integer greater than or equal to 1
    Default: 15

    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.

  • transpose
    Parent: data[type=contourcarpet]
    Type: boolean

    Transposes the z data.

  • uirevision
    Parent: data[type=contourcarpet]
    Type: number or categorical coordinate string

    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.
