  Type: number greater than or equal to 0
  Default: 0

  Sets a distance, in pixels, to move the end arrowhead away from the position it is pointing at, for example to point at the edge of a marker independent of zoom. Note that this shortens the arrow from the `ax` / `ay` vector, in contrast to `xshift` / `yshift` which moves everything by this amount.

• startarrowhead

• templateitemname
  Parent: layout.scene.annotations[]
  Type: string

  Used to refer to a named item in this array in the template. Named items from the template will be created even without a matching item in the input figure, but you can modify one by making an item with `templateitemname` matching its `name`, alongside your modifications (including `visible: false` or `enabled: false` to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it with `visible: true`.

• text
  Parent: layout.scene.annotations[]
  Type: string

  Sets the text associated with this annotation. Plotly uses a subset of HTML tags to do things like newline (<br>), bold (<b></b>), italics (<i></i>), hyperlinks (<a href='...'></a>). Tags <em>, <sup>, <sub>, <s>, <u> <span> are also supported.

• textangle
  Parent: layout.scene.annotations[]
  Type: angle
  Default: 0

  Sets the angle at which the `text` is drawn with respect to the horizontal.

• valign
  Parent: layout.scene.annotations[]
  Type: enumerated , one of ( "top" | "middle" | "bottom" )
  Default: "middle"

  Type: boolean
  Default: true

  Determines whether or not this annotation is visible.

• width
  Parent: layout.scene.annotations[]
  Type: number greater than or equal to 1

• x
  Parent: layout.scene.annotations[]
  Type: number or categorical coordinate string

  Sets the annotation's x position.

• xanchor
  Parent: layout.scene.annotations[]
  Type: enumerated , one of ( "auto" | "left" | "center" | "right" )
  Default: "auto"

  Sets the text box's horizontal position anchor This anchor binds the `x` position to the "left", "center" or "right" of the annotation. For example, if `x` is set to 1, `xref` to "paper" and `xanchor` to "right" then the right-most portion of the annotation lines up with the right-most edge of the plotting area. If "auto", the anchor is equivalent to "center" for data-referenced annotations or if there is an arrow, whereas for paper-referenced with no arrow, the anchor picked corresponds to the closest side.

• xshift
  Parent: layout.scene.annotations[]
  Type: number
  Default: 0

• yanchor
  Parent: layout.scene.annotations[]
  Type: enumerated , one of ( "auto" | "top" | "middle" | "bottom" )
  Default: "auto"

For example, if `y` is set to 1, `yref` to "paper" and `yanchor` to "top" then the top-most portion of the annotation lines up with the top-most edge of the plotting area. If "auto", the anchor is equivalent to "middle" for data-referenced annotations or if there is an arrow, whereas for paper-referenced with no arrow, the anchor picked corresponds to the closest side.

• yshift
  Parent: layout.scene.annotations[]

  Determines whether or not the range of this axis is computed in relation to the input data. See `rangemode` for more info. If `range` is provided and it has a value for both the lower and upper bound, `autorange` is set to "false". Using "min" applies autorange only to set the minimum. Using "max" applies autorange only to set the maximum. Using "min reversed" applies autorange only to set the minimum on a reversed axis. Using "max reversed" applies autorange only to set the maximum on a reversed axis. Using "reversed" applies autorange on both ends and reverses the axis direction.

• autorangeoptions
  Parent: layout.scene.xaxis
  Type: object containing one or more of the keys listed below.
  • clipmax
    Parent: layout.scene.xaxis.autorangeoptions

• backgroundcolor
  Parent: layout.scene.xaxis
  Type: color
  Default: "rgba(204, 204, 204, 0.5)"

  Sets the background color of this axis' wall.

  Type: enumerated , one of ( "chinese" | "coptic" | "discworld" | "ethiopian" | "gregorian" | "hebrew" | "islamic" | "jalali" | "julian" | "mayan" | "nanakshahi" | "nepali" | "persian" | "taiwan" | "thai" | "ummalqura" )
  Default: "gregorian"

  Sets the calendar system to use for `range` and `tick0` if this is a date axis. This does not set the calendar for interpreting data on this axis, that's specified in the trace or via the global `layout.calendar`

• categoryarray
  Parent: layout.scene.xaxis
  Type: data array

  Sets the order in which categories on this axis appear. Only has an effect if `categoryorder` is set to "array". Used with `categoryorder`.

• categoryorder
  Parent: layout.scene.xaxis
  Type: enumerated , one of ( "trace" | "category ascending" | "category descending" | "array" | "total ascending" | "total descending" | "min ascending" | "min descending" | "max ascending" | "max descending" | "sum ascending" | "sum descending" | "mean ascending" | "mean descending" | "geometric mean ascending" | "geometric mean descending" | "median ascending" | "median descending" )
  Default: "trace"

  Specifies the ordering logic for the case of categorical variables. By default, plotly uses "trace", which specifies the order that is present in the data supplied. Set `categoryorder` to "category ascending" or "category descending" if order should be determined by the alphanumerical order of the category names. Set `categoryorder` to "array" to derive the ordering from the attribute `categoryarray`. If a category is not found in the `categoryarray` array, the sorting behavior for that attribute will be identical to the "trace" mode. The unspecified categories will follow the categories in `categoryarray`. Set `categoryorder` to "total ascending" or "total descending" if order should be determined by the numerical order of the values. Similarly, the order can be determined by the min, max, sum, mean, geometric mean or median of all the values.

• color
  Parent: layout.scene.xaxis
  Type: color
  Default: "#444"

  Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.

• dtick
  Parent: layout.scene.xaxis
  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"

• exponentformat
  Parent: layout.scene.xaxis
  Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )
  Default: "B"

  Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.

• gridcolor
  Parent: layout.scene.xaxis
  Type: color
  Default: "rgb(204, 204, 204)"

  Sets the color of the grid lines.

• gridwidth
  Parent: layout.scene.xaxis
  Type: number greater than or equal to 0
  Default: 1

  Sets the width (in px) of the grid lines.

• hoverformat
  Parent: layout.scene.xaxis
  Type: string
  Default: ""

  Sets the hover text 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. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"

• labelalias
  Parent: layout.scene.xaxis
  Type: number or categorical coordinate string

  Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

• linecolor
  Parent: layout.scene.xaxis
  Type: color
  Default: "#444"

  Sets the axis line color.

• linewidth
  Parent: layout.scene.xaxis

Has no effect outside of a template.

  • templateitemname
    Parent: layout.scene.xaxis.tickformatstops[]
    Type: string

    Used to refer to a named item in this array in the template. Named items from the template will be created even without a matching item in the input figure, but you can modify one by making an item with `templateitemname` matching its `name`, alongside your modifications (including `visible: false` or `enabled: false` to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it with `visible: true`.

• type
  Parent: layout.scene.xaxis
  Type: enumerated , one of ( "-" | "linear" | "log" | "date" | "category" )
  Default: "-"

  Default: true

  Determines whether or not the range of this axis is computed in relation to the input data. See `rangemode` for more info. If `range` is provided and it has a value for both the lower and upper bound, `autorange` is set to "false". Using "min" applies autorange only to set the minimum. Using "max" applies autorange only to set the maximum. Using "min reversed" applies autorange only to set the minimum on a reversed axis. Using "max reversed" applies autorange only to set the maximum on a reversed axis. Using "reversed" applies autorange on both ends and reverses the axis direction.

• autorangeoptions
  Parent: layout.scene.yaxis
  Type: object containing one or more of the keys listed below.
  • clipmax
    Parent: layout.scene.yaxis.autorangeoptions

  Default: "convert types"

  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. Defaults to layout.autotypenumbers.

• backgroundcolor
  Parent: layout.scene.yaxis
  Type: color
  Default: "rgba(204, 204, 204, 0.5)"

  Sets the background color of this axis' wall.

  Default: "gregorian"

  Sets the calendar system to use for `range` and `tick0` if this is a date axis. This does not set the calendar for interpreting data on this axis, that's specified in the trace or via the global `layout.calendar`

• categoryarray
  Parent: layout.scene.yaxis
  Type: data array

  Sets the order in which categories on this axis appear. Only has an effect if `categoryorder` is set to "array". Used with `categoryorder`.

• categoryorder
  Parent: layout.scene.yaxis
  Type: enumerated , one of ( "trace" | "category ascending" | "category descending" | "array" | "total ascending" | "total descending" | "min ascending" | "min descending" | "max ascending" | "max descending" | "sum ascending" | "sum descending" | "mean ascending" | "mean descending" | "geometric mean ascending" | "geometric mean descending" | "median ascending" | "median descending" )
  Default: "trace"

  Specifies the ordering logic for the case of categorical variables. By default, plotly uses "trace", which specifies the order that is present in the data supplied. Set `categoryorder` to "category ascending" or "category descending" if order should be determined by the alphanumerical order of the category names. Set `categoryorder` to "array" to derive the ordering from the attribute `categoryarray`. If a category is not found in the `categoryarray` array, the sorting behavior for that attribute will be identical to the "trace" mode. The unspecified categories will follow the categories in `categoryarray`. Set `categoryorder` to "total ascending" or "total descending" if order should be determined by the numerical order of the values. Similarly, the order can be determined by the min, max, sum, mean, geometric mean or median of all the values.

• color
  Parent: layout.scene.yaxis
  Type: color
  Default: "#444"

  Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.

• dtick
  Parent: layout.scene.yaxis
  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"

• exponentformat
  Parent: layout.scene.yaxis
  Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )
  Default: "B"

  Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.

• gridcolor
  Parent: layout.scene.yaxis
  Type: color
  Default: "rgb(204, 204, 204)"

  Sets the color of the grid lines.

• gridwidth
  Parent: layout.scene.yaxis
  Type: number greater than or equal to 0
  Default: 1

  Sets the width (in px) of the grid lines.

• hoverformat
  Parent: layout.scene.yaxis
  Type: string
  Default: ""

  Sets the hover text 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. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"

• labelalias
  Parent: layout.scene.yaxis
  Type: number or categorical coordinate string

  Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

• linecolor
  Parent: layout.scene.yaxis
  Type: color
  Default: "#444"

• mirror
  Parent: layout.scene.yaxis
  Type: enumerated , one of ( true | "ticks" | false | "all" | "allticks" )

  Determines if the axis lines or/and ticks are mirrored to the opposite side of the plotting area. If "true", the axis lines are mirrored. If "ticks", the axis lines and ticks are mirrored. If "false", mirroring is disable. If "all", axis lines are mirrored on all shared-axes subplots. If "allticks", axis lines and ticks are mirrored on all shared-axes subplots.

• nticks
  Parent: layout.scene.yaxis
  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".

• range
  Parent: layout.scene.yaxis
  Type: array

  Sets the range of this axis. If the axis `type` is "log", then you must take the log of your desired range (e.g. to set the range from 1 to 100, set the range from 0 to 2). If the axis `type` is "date", it should be date strings, like date data, though Date objects and unix milliseconds will be accepted and converted to strings. If the axis `type` is "category", it should be numbers, using the scale where each category is assigned a serial number from zero in the order it appears. Leaving either or both elements `null` impacts the default `autorange`.

• rangemode
  Parent: layout.scene.yaxis

• type
  Parent: layout.scene.yaxis
  Type: enumerated , one of ( "-" | "linear" | "log" | "date" | "category" )
  Default: "-"

  Default: true

  Determines whether or not the range of this axis is computed in relation to the input data. See `rangemode` for more info. If `range` is provided and it has a value for both the lower and upper bound, `autorange` is set to "false". Using "min" applies autorange only to set the minimum. Using "max" applies autorange only to set the maximum. Using "min reversed" applies autorange only to set the minimum on a reversed axis. Using "max reversed" applies autorange only to set the maximum on a reversed axis. Using "reversed" applies autorange on both ends and reverses the axis direction.

• autorangeoptions
  Parent: layout.scene.zaxis
  Type: object containing one or more of the keys listed below.
  • clipmax
    Parent: layout.scene.zaxis.autorangeoptions

• backgroundcolor
  Parent: layout.scene.zaxis
  Type: color
  Default: "rgba(204, 204, 204, 0.5)"

  Sets the background color of this axis' wall.

  Default: "gregorian"

  Sets the calendar system to use for `range` and `tick0` if this is a date axis. This does not set the calendar for interpreting data on this axis, that's specified in the trace or via the global `layout.calendar`

• categoryarray
  Parent: layout.scene.zaxis
  Type: data array

  Sets the order in which categories on this axis appear. Only has an effect if `categoryorder` is set to "array". Used with `categoryorder`.

• categoryorder
  Parent: layout.scene.zaxis
  Type: enumerated , one of ( "trace" | "category ascending" | "category descending" | "array" | "total ascending" | "total descending" | "min ascending" | "min descending" | "max ascending" | "max descending" | "sum ascending" | "sum descending" | "mean ascending" | "mean descending" | "geometric mean ascending" | "geometric mean descending" | "median ascending" | "median descending" )
  Default: "trace"

  Specifies the ordering logic for the case of categorical variables. By default, plotly uses "trace", which specifies the order that is present in the data supplied. Set `categoryorder` to "category ascending" or "category descending" if order should be determined by the alphanumerical order of the category names. Set `categoryorder` to "array" to derive the ordering from the attribute `categoryarray`. If a category is not found in the `categoryarray` array, the sorting behavior for that attribute will be identical to the "trace" mode. The unspecified categories will follow the categories in `categoryarray`. Set `categoryorder` to "total ascending" or "total descending" if order should be determined by the numerical order of the values. Similarly, the order can be determined by the min, max, sum, mean, geometric mean or median of all the values.

• color
  Parent: layout.scene.zaxis
  Type: color
  Default: "#444"

  Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.

• dtick
  Parent: layout.scene.zaxis
  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"

• exponentformat
  Parent: layout.scene.zaxis
  Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )
  Default: "B"

  Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.

• gridcolor
  Parent: layout.scene.zaxis
  Type: color
  Default: "rgb(204, 204, 204)"

  Sets the color of the grid lines.

• gridwidth

  Type: number greater than or equal to 0
  Default: 1

  Sets the width (in px) of the grid lines.

• hoverformat
  Parent: layout.scene.zaxis
  Type: string
  Default: ""

  Sets the hover text 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. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"

• labelalias
  Parent: layout.scene.zaxis
  Type: number or categorical coordinate string

  Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

• linecolor
  Parent: layout.scene.zaxis
  Type: color

• mirror
  Parent: layout.scene.zaxis
  Type: enumerated , one of ( true | "ticks" | false | "all" | "allticks" )

  Determines if the axis lines or/and ticks are mirrored to the opposite side of the plotting area. If "true", the axis lines are mirrored. If "ticks", the axis lines and ticks are mirrored. If "false", mirroring is disable. If "all", axis lines are mirrored on all shared-axes subplots. If "allticks", axis lines and ticks are mirrored on all shared-axes subplots.

• nticks
  Parent: layout.scene.zaxis
  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".

• range
  Parent: layout.scene.zaxis
  Type: array

  Sets the range of this axis. If the axis `type` is "log", then you must take the log of your desired range (e.g. to set the range from 1 to 100, set the range from 0 to 2). If the axis `type` is "date", it should be date strings, like date data, though Date objects and unix milliseconds will be accepted and converted to strings. If the axis `type` is "category", it should be numbers, using the scale where each category is assigned a serial number from zero in the order it appears. Leaving either or both elements `null` impacts the default `autorange`.

• rangemode
  Parent: layout.scene.zaxis
  Type: enumerated , one of ( "normal" | "tozero" | "nonnegative" )
  Default: "normal"

  If "normal", the range is computed in relation to the extrema of the input data. If "tozero"`, the range extends to 0, regardless of the input data If "nonnegative", the range is non-negative, regardless of the input data. Applies only to linear axes.

We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"
