Sets the opacity of the trace.

Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.

Sets the values of the sectors. If omitted, we count occurrences of each label.

Sets the sector labels. If `labels` entries are duplicated, we sum associated `values` or simply count occurrences if `values` is not provided. For other array attributes (including color) we use the first non-empty entry among all occurrences of the label.

Sets the label step. See `label0` for more info.

Alternate to `labels`. Builds a numeric set of labels. Use with `dlabel` where `label0` is the starting label and `dlabel` the step.

Sets the fraction of larger radius to pull the sectors out from the center. This can be a constant to pull all slices apart from each other equally or an array to highlight one or more slices.

Sets text elements associated with each sector. If trace `textinfo` contains a "text" flag, these elements will be seen on the chart. If trace `hoverinfo` contains a "text" flag and "hovertext" is not set, these elements will be seen in the hover labels.

Specifies the location of the `textinfo`.

Template string used for rendering the information text that appear on points. Note that this will override `textinfo`. Variables are inserted using %{variable}, for example "y: %{y}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. Every attributes that can be specified per-point (the ones that are `arrayOk: True`) are available. Finally, the template string has access to variables `label`, `color`, `value`, `percent` and `text`.

Sets hover text elements associated with each sector. If a single string, the same string appears for all data points. If an array of string, the items are mapped in order of this trace's sectors. To be seen, trace `hoverinfo` must contain a "text" flag.

Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

Template string used for rendering the information that appear on hover box. Note that this will override `hoverinfo`. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%_xother}, {%_xother_}, {%xother_}. When showing info for several points, "xother" will be added to those with different x positions from the first point. An underscore before or after "(x|y)other" will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available in `hovertemplate` are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are `arrayOk: True`) are available. Finally, the template string has access to variables `label`, `color`, `value`, `percent` and `text`. Anything contained in tag `<extra>` is displayed in the secondary box, for example "<extra>{fullData.name}</extra>". To hide the secondary box completely, use an empty tag `<extra></extra>`.

Assigns extra meta information associated with this trace that can be used in various text attributes. Attributes such as trace `name`, graph, axis and colorbar `title.text`, annotation `text` `rangeselector`, `updatemenues` and `sliders` `label` text all support `meta`. To access the trace `meta` values in an attribute in the same trace, simply use `%{meta[i]}` where `i` is the index or key of the `meta` item in question. To access trace `meta` in layout attributes, use `%{data[n[.meta[i]}` where `i` is the index or key of the `meta` and `n` is the trace index.

Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, "scatter" traces also appends customdata items in the markers DOM elements

  Type: enumerated or array of enumerateds , 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
  Code: fig.update_traces(insidetextfont_variant=<VALUE>, selector=dict(type='pie'))
  Type: enumerated or array of enumerateds , one of ( "normal" | "small-caps" | "all-small-caps" | "all-petite-caps" | "petite-caps" | "unicase" )
  Default: "normal"

  Sets the variant of the font.

• weight
  Code: fig.update_traces(insidetextfont_weight=<VALUE>, selector=dict(type='pie'))
  Type: integer or array of integers between or equal to 1 and 1000
  Default: normal

  Sets the weight (or boldness) of the font.

Controls the orientation of the text inside chart sectors. When set to "auto", text may be oriented in any direction in order to be as big as possible in the middle of a sector. The "horizontal" option orients text to be parallel with the bottom of the chart, and may make text smaller in order to achieve that goal. The "radial" option orients text along the radius of the sector. The "tangential" option orients text perpendicular to the radius of the sector.

Sets the font used for `textinfo` lying outside the sector.

• color
  Code: fig.update_traces(outsidetextfont_color=<VALUE>, selector=dict(type='pie'))
  Type: color or array of colors
• family
  Code: fig.update_traces(outsidetextfont_family=<VALUE>, selector=dict(type='pie'))
  Type: string or array of strings

  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
  Code: fig.update_traces(outsidetextfont_lineposition=<VALUE>, selector=dict(type='pie'))
  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
  Code: fig.update_traces(outsidetextfont_shadow=<VALUE>, selector=dict(type='pie'))
  Type: string or array of strings
  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
  Code: fig.update_traces(outsidetextfont_size=<VALUE>, selector=dict(type='pie'))
  Type: number or array of numbers greater than or equal to 1
• style
  Code: fig.update_traces(outsidetextfont_style=<VALUE>, selector=dict(type='pie'))
  Type: enumerated or array of enumerateds , one of ( "normal" | "italic" )
  Default: "normal"

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

• textcase
  Code: fig.update_traces(outsidetextfont_textcase=<VALUE>, selector=dict(type='pie'))
  Type: enumerated or array of enumerateds , 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
  Code: fig.update_traces(outsidetextfont_variant=<VALUE>, selector=dict(type='pie'))
  Type: enumerated or array of enumerateds , one of ( "normal" | "small-caps" | "all-small-caps" | "all-petite-caps" | "petite-caps" | "unicase" )
  Default: "normal"

  Sets the variant of the font.

• weight
  Code: fig.update_traces(outsidetextfont_weight=<VALUE>, selector=dict(type='pie'))
  Type: integer or array of integers between or equal to 1 and 1000
  Default: normal

  Sets the weight (or boldness) of the font.

Instead of the first slice starting at 12 o'clock, rotate to some other angle.

If there are multiple pie charts that should be sized according to their totals, link them by providing a non-empty group id here shared by every trace in the same group.

Determines whether or not the sectors are reordered from largest to smallest.

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.
