DESCRIPTION

Parallel categories diagram for multidimensional categorical data.

This file has been autogenerated from the official plotly.js source.

DISCLAIMER

This is an unofficial Plotly Perl module. Currently I'm not affiliated in any way with Plotly. But I think plotly.js is a great library and I want to use it with perl.

METHODS

TO_JSON

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

type

Trace type.

ATTRIBUTES

• arrangement

  Sets the drag interaction mode for categories and dimensions. If `perpendicular`, the categories can only move along a line perpendicular to the paths. If `freeform`, the categories can freely move on the plane. If `fixed`, the categories and dimensions are stationary.

• bundlecolors

  Sort paths so that like colors are bundled together within each category.

• counts

  The number of observations represented by each state. Defaults to 1 so that each state represents one observation

• countssrc

  Sets the source reference on plot.ly for counts .

• dimensions

• domain

• 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.

• hoveron

  Sets the hover interaction mode for the parcats diagram. If `category`, hover interaction take place per category. If `color`, hover interactions take place per color per category. If `dimension`, hover interactions take place across all categories per dimension.

• 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}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". See https://github.com/d3/d3-format/blob/master/README.md#locale_format for details on the formatting syntax. The variables available in `hovertemplate` are the ones emitted as event data described at this link https://plot.ly/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available. variables `count`, `probability`, `category`, `categorycount`, `colorcount` and `bandcolorcount`. 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>`.

• labelfont

• line

• name

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

• sortpaths

  Sets the path sorting algorithm. If `forward`, sort paths based on dimension categories from left to right. If `backward`, sort paths based on dimensions categories from right to left.

• stream

• tickfont

• 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.

• 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).
