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.

ATTRIBUTES

• color

  Sets the `node` color. It can be a single value, or an array for specifying color for each `node`. If `node.color` is omitted, then the default `Plotly` color palette will be cycled through to have a variety of colors. These defaults are not fully opaque, to allow some visibility of what is beneath the node.

• colorsrc

  Sets the source reference on plot.ly for color .

• description

• groups

  Groups of nodes. Each group is defined by an array with the indices of the nodes it contains. Multiple groups can be specified.

• hoverinfo

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

• 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}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#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/d3-3.x-api-reference/blob/master/Time-Formatting.md#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://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 `value` and `label`. 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 plot.ly for hovertemplate .

• label

  The shown name of the node.

• labelsrc

  Sets the source reference on plot.ly for label .

• line

• pad

  Sets the padding (in px) between the `nodes`.

• thickness

  Sets the thickness (in px) of the `nodes`.

• x

  The normalized horizontal position of the node.

• xsrc

  Sets the source reference on plot.ly for x .

• y

  The normalized vertical position of the node.

• ysrc

  Sets the source reference on plot.ly for y .
