SYNOPSIS

use Chart::Plotly qw(show_plot);
use Chart::Plotly::Trace::Sankey;
# Example data from: https://plot.ly/javascript/sankey-diagram/#basic-sankey-diagram
my $sankey = Chart::Plotly::Trace::Sankey->new(
    orientation => "h",
    node        => {
        pad       => 15,
        thickness => 30,
        line      => {
            color => "black",
            width => 0.5
        },
        label     => [ "A1", "A2", "B1", "B2", "C1", "C2" ],
        color     => [ "blue", "blue", "blue", "blue", "blue", "blue" ]
    },

    link        => {
        source => [ 0, 1, 0, 2, 3, 3 ],
        target => [ 2, 3, 3, 4, 4, 5 ],
        value  => [ 8, 4, 2, 8, 4, 2 ]
    }
);

show_plot([ $sankey ]);

DESCRIPTION

Sankey plots for network flow data analysis. The nodes are specified in `nodes` and the links between sources and targets in `links`. The colors are set in `nodes[i].color` and `links[i].color`; otherwise defaults are used.

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

NAME

Chart::Plotly::Trace::Sankey

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

    If value is `snap` (the default), the node arrangement is assisted by automatic snapping of elements to preserve space between nodes specified via `nodepad`. If value is `perpendicular`, the nodes can only move along a line perpendicular to the flow. If value is `freeform`, the nodes can freely move on the plane. If value is `fixed`, the nodes are stationary.

  • 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 plot.ly for customdata .

  • 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.

  • hoverinfosrc

    Sets the source reference on plot.ly for hoverinfo .

  • hoverlabel

  • 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 plot.ly for ids .

  • 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.

  • link

  • name

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

  • node

  • opacity

    Sets the opacity of the trace.

  • orientation

    Sets the orientation of the Sankey diagram.

  • selectedpoints

    Array containing integer indices of selected points. Has an effect only for traces that support selections. Note that an empty array means an empty selection where the `unselected` are turned on for all points, whereas, any other non-array values means no selection all where the `selected` and `unselected` styles have no effect.

  • showlegend

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

  • stream

  • textfont

  • uid

  • valueformat

    Sets the value formatting rule using d3 formatting mini-language which is similar to those of Python. See https://github.com/d3/d3-format/blob/master/README.md#locale_format

  • valuesuffix

    Adds a unit to follow the value in the hover tooltip. Add a space if a separation is necessary from the value.

  • 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).
