NAME

Chart::Plotly::Trace::Histogram2dcontour::Contours - This attribute is one of the possible options for the trace histogram2dcontour.

VERSION

version 0.038

SYNOPSIS

use HTML::Show;
use Chart::Plotly;
use Chart::Plotly::Trace::Histogram2dcontour;
my $histogram2dcontour =
  Chart::Plotly::Trace::Histogram2dcontour->new( x => [ map { int( 10 * rand() ) } ( 1 .. 500 ) ],
                                                 y => [ map { int( 10 * rand() ) } ( 1 .. 500 ) ] );

HTML::Show::show( Chart::Plotly::render_full_html( data => [$histogram2dcontour] ) );

DESCRIPTION

This attribute is part of the possible options for the trace histogram2dcontour.

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.

ATTRIBUTES

  • coloring

    Determines the coloring method showing the contour values. If *fill*, coloring is done evenly between each contour level If *heatmap*, a heatmap gradient coloring is applied between each contour level. If *lines*, coloring is done on the contour lines. If *none*, no coloring is applied on this trace.

  • end

    Sets the end contour level value. Must be more than `contours.start`

  • impliedEdits

  • labelfont

  • labelformat

    Sets the contour label formatting rule using d3 formatting mini-language which is very similar to Python, see: https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format

  • operation

    Sets the constraint operation. *=* keeps regions equal to `value` *<* and *<=* keep regions less than `value` *>* and *>=* keep regions greater than `value` *[]*, *()*, *[)*, and *(]* keep regions inside `value[0]` to `value[1]` *][*, *)(*, *](*, *)[* keep regions outside `value[0]` to value[1]` Open vs. closed intervals make no difference to constraint display, but all versions are allowed for consistency with filter transforms.

  • showlabels

    Determines whether to label the contour lines with their values.

  • showlines

    Determines whether or not the contour lines are drawn. Has an effect only if `contours.coloring` is set to *fill*.

  • size

    Sets the step between each contour level. Must be positive.

  • start

    Sets the starting contour level value. Must be less than `contours.end`

  • value

    Sets the value or values of the constraint boundary. When `operation` is set to one of the comparison values (=,<,>=,>,<=) *value* is expected to be a number. When `operation` is set to one of the interval values ([],(),[),(],][,)(,](,)[) *value* is expected to be an array of two numbers where the first is the lower bound and the second is the upper bound.
