• autotypenumbers
  Code: fig.update_polars(angularaxis_autotypenumbers=<VALUE>)
  Type: enumerated , one of ( "convert types" | "strict" )
  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.

• categoryarray
  Code: fig.update_polars(angularaxis_categoryarray=<VALUE>)
  Type: list, numpy array, or Pandas series of numbers, strings, or datetimes.

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

• categoryorder
  Code: fig.update_polars(angularaxis_categoryorder=<VALUE>)
  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" | "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 or median of all the values.

• color
  Code: fig.update_polars(angularaxis_color=<VALUE>)
  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.

• direction
  Code: fig.update_polars(angularaxis_direction=<VALUE>)
  Type: enumerated , one of ( "counterclockwise" | "clockwise" )
  Default: "counterclockwise"

  Sets the direction corresponding to positive angles.

• dtick
  Code: fig.update_polars(angularaxis_dtick=<VALUE>)
  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"

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
  Code: fig.update_polars(angularaxis_labelalias=<VALUE>)
  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.

  Code: fig.update_polars(angularaxis_nticks=<VALUE>)
  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".

• period
  Code: fig.update_polars(angularaxis_period=<VALUE>)
  Type: number greater than or equal to 0

  Set the angular period. Has an effect only when `angularaxis.type` is "category".

• rotation
  Code: fig.update_polars(angularaxis_rotation=<VALUE>)

  Code: fig.update_polars(radialaxis_autotypenumbers=<VALUE>)
  Type: enumerated , one of ( "convert types" | "strict" )
  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.

• calendar
  Code: fig.update_polars(radialaxis_calendar=<VALUE>)
  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
  Code: fig.update_polars(radialaxis_categoryarray=<VALUE>)
  Type: list, numpy array, or Pandas series of numbers, strings, or datetimes.

  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 or median of all the values.

• color
  Code: fig.update_polars(radialaxis_color=<VALUE>)
  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
  Code: fig.update_polars(radialaxis_dtick=<VALUE>)
  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"

  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").

• gridwidth
  Code: fig.update_polars(radialaxis_gridwidth=<VALUE>)
  Type: number greater than or equal to 0
  Default: 1

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

• hoverformat
  Code: fig.update_polars(radialaxis_hoverformat=<VALUE>)
  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
  Code: fig.update_polars(radialaxis_labelalias=<VALUE>)
  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.

• layer
  Code: fig.update_polars(radialaxis_layer=<VALUE>)
  Type: enumerated , one of ( "above traces" | "below traces" )
  Default: "above traces"

  Sets the layer on which this axis is displayed. If "above traces", this axis is displayed above all the subplot's traces If "below traces", this axis is displayed below all the subplot's traces, but above the grid lines. Useful when used together with scatter-like traces with `cliponaxis` set to "False" to show markers and/or text nodes above this axis.

• nticks
  Code: fig.update_polars(radialaxis_nticks=<VALUE>)
  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
  Code: fig.update_polars(radialaxis_range=list(...))
  Type: list

  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
  Code: fig.update_polars(radialaxis_rangemode=<VALUE>)
  Type: enumerated , one of ( "tozero" | "nonnegative" | "normal" )
  Default: "tozero"

  If "tozero"`, the range extends to 0, regardless of the input data If "nonnegative", the range is non-negative, regardless of the input data. If "normal", the range is computed in relation to the extrema of the input data (same behavior as for cartesian axes).

• separatethousands
  Code: fig.update_polars(radialaxis_separatethousands=<VALUE>)
  Type: boolean

  If "True", even 4-digit integers are separated

  If "all", all tick labels are displayed with a prefix. If "first", only the first tick is displayed with a prefix. If "last", only the last tick is displayed with a suffix. If "none", tick prefixes are hidden.

• showticksuffix
  Code: fig.update_polars(radialaxis_showticksuffix=<VALUE>)
  Type: enumerated , one of ( "all" | "first" | "last" | "none" )
  Default: "all"

  Same as `showtickprefix` but for tick suffixes.

• side
  Code: fig.update_polars(radialaxis_side=<VALUE>)
  Type: enumerated , one of ( "clockwise" | "counterclockwise" )
  Default: "clockwise"

  Determines on which side of radial axis line the tick and tick labels appear.

• tick0
  Code: fig.update_polars(radialaxis_tick0=<VALUE>)
  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.

• tickangle
  Code: fig.update_polars(radialaxis_tickangle=<VALUE>)
  Type: angle
  Default: "auto"

  • name
    Parent: layout.polar.radialaxis.tickformatstops[]
    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
