NAME

Chart::Plotly::Trace::Splom - Splom traces generate scatter plot matrix visualizations. Each splom `dimensions` items correspond to a generated axis. Values for each of those dimensions are set in `dimensions[i].values`. Splom traces support all `scattergl` marker style attributes. Specify `layout.grid` attributes and/or layout x-axis and y-axis attributes for more control over the axis positioning and style.

SYNOPSIS

use Chart::Plotly qw(show_plot);
use Chart::Plotly::Trace::Splom;

use Data::Dataset::Classic::Iris;

my $convert_array_to_arrayref = sub {[@_]};
my $iris = Data::Dataset::Classic::Iris::get(as => 'Data::Table');
my $data = $iris->group(['species'],[$iris->header], [$convert_array_to_arrayref, $convert_array_to_arrayref, $convert_array_to_arrayref, $convert_array_to_arrayref, $convert_array_to_arrayref], [map { join "", map {ucfirst} split /_/, $_ } $iris->header], 0 );

DESCRIPTION

Splom traces generate scatter plot matrix visualizations. Each splom `dimensions` items correspond to a generated axis. Values for each of those dimensions are set in `dimensions[i].values`. Splom traces support all `scattergl` marker style attributes. Specify `layout.grid` attributes and/or layout x-axis and y-axis attributes for more control over the axis positioning and style.

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

• 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 .

• diagonal

• dimensions

• 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

• 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. 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 .

• hovertext

  Same as `text`.

• hovertextsrc

  Sets the source reference on plot.ly 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 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.

• 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 plot.ly 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.

• selected

• 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.

• showlowerhalf

  Determines whether or not subplots on the lower half from the diagonal are displayed.

• showupperhalf

  Determines whether or not subplots on the upper half from the diagonal are displayed.

• stream

• text

  Sets text elements associated with each (x,y) pair to appear on hover. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (x,y) coordinates.

• textsrc

  Sets the source reference on plot.ly for text .

• 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.

• unselected

• 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).

• xaxes

  Sets the list of x axes corresponding to dimensions of this splom trace. By default, a splom will match the first N xaxes where N is the number of input dimensions. Note that, in case where `diagonal.visible` is false and `showupperhalf` or `showlowerhalf` is false, this splom trace will generate one less x-axis and one less y-axis.

• yaxes

  Sets the list of y axes corresponding to dimensions of this splom trace. By default, a splom will match the first N yaxes where N is the number of input dimensions. Note that, in case where `diagonal.visible` is false and `showupperhalf` or `showlowerhalf` is false, this splom trace will generate one less x-axis and one less y-axis.
