METHODS

TO_JSON

Serialize the trace to JSON. This method should be called only by JSON serializer.

type

Trace type.

ATTRIBUTES

  • automargin

    Determines whether outside text labels can push the margins.

  • customdata

    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

  • customdatasrc

    Sets the source reference on Chart Studio Cloud for `customdata`.

  • direction

    Specifies the direction at which succeeding sectors follow one another.

  • dlabel

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

  • domain

  • hole

    Sets the fraction of the radius to cut out of the pie. Use this to make a donut chart.

  • hoverinfo

    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.

  • hoverinfosrc

    Sets the source reference on Chart Studio Cloud for `hoverinfo`.

  • hoverlabel

  • hovertemplate

    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. 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>`.

  • hovertemplatesrc

    Sets the source reference on Chart Studio Cloud for `hovertemplate`.

  • hovertext

    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.

  • hovertextsrc

    Sets the source reference on Chart Studio Cloud for `hovertext`.

  • ids

    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.

  • idssrc

    Sets the source reference on Chart Studio Cloud for `ids`.

  • insidetextfont

  • insidetextorientation

    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.

  • label0

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

  • labels

    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.

  • labelssrc

    Sets the source reference on Chart Studio Cloud for `labels`.

  • legendgroup

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

  • legendgrouptitle

  • legendrank

    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.

  • marker

  • pmeta

    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.

  • metasrc

    Sets the source reference on Chart Studio Cloud for `meta`.

  • name

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

  • opacity

    Sets the opacity of the trace.

  • outsidetextfont

  • pull

    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.

  • pullsrc

    Sets the source reference on Chart Studio Cloud for `pull`.

  • rotation

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

  • scalegroup

    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.

  • showlegend

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

  • sort

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

  • stream

  • text

    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.

  • textfont

  • textinfo

    Determines which trace information appear on the graph.

  • textposition

    Specifies the location of the `textinfo`.

  • textpositionsrc

    Sets the source reference on Chart Studio Cloud for `textposition`.

  • textsrc

    Sets the source reference on Chart Studio Cloud for `text`.

  • texttemplate

    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. variables `label`, `color`, `value`, `percent` and `text`.

  • texttemplatesrc

    Sets the source reference on Chart Studio Cloud for `texttemplate`.

  • title

  • transforms

  • uid

    Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.

  • uirevision

    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.

  • values

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

  • valuessrc

    Sets the source reference on Chart Studio Cloud for `values`.

  • visible

    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).
