NAME

Chart::Plotly::Trace::Contour

VERSION

version 0.014

SYNOPSIS

 use Chart::Plotly qw(show_plot);
 use Chart::Plotly::Trace::Contour;
 use English qw(-no_match_vars);
 
 my $contour = Chart::Plotly::Trace::Contour->new(
     x => [ 0 .. 10 ],
     y => [ 0 .. 10 ],
     z => [
         map {
             my $y = $ARG;
             [ map { $ARG * $ARG + $y * $y } ( 0 .. 10 ) ]
         } ( 0 .. 10 )
     ]
 );
 
 show_plot( [$contour] );

DESCRIPTION

The data from which contour lines are computed is set in `z`. Data in `z` must be a {2D array} of numbers. Say that `z` has N rows and M columns, then by default, these N rows correspond to N y coordinates (set in `y` or auto-generated) and the M columns correspond to M x coordinates (set in `x` or auto-generated). By setting `transpose` to *true*, the above behavior is flipped.

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

NAME

Chart::Plotly::Trace::Contour

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

  • autocolorscale

    Determines whether or not the colorscale is picked using the sign of the input z values.

  • autocontour

    Determines whether or not the contour level attributes are picked by an algorithm. If *true*, the number of contour levels can be set in `ncontours`. If *false*, set the contour level attributes in `contours`.

  • colorbar

  • colorscale

    Sets the colorscale. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)', [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in z space, use zmin and zmax

  • connectgaps

    Determines whether or not gaps (i.e. {nan} or missing values) in the `z` data are filled in.

  • contours

  • 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 .

  • dx

    Sets the x coordinate step. See `x0` for more info.

  • dy

    Sets the y coordinate step. See `y0` for more info.

  • fillcolor

    Sets the fill color if `contours.type` is *constraint*. Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available.

  • 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.

  • line

  • name

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

  • ncontours

    Sets the maximum number of contour levels. The actual number of contours will be chosen automatically to be less than or equal to the value of `ncontours`. Has an effect only if `autocontour` is *true* or if `contours.size` is missing.

  • opacity

    Sets the opacity of the trace.

  • reversescale

    Reverses the colorscale.

  • 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.

  • showscale

    Determines whether or not a colorbar is displayed for this trace.

  • stream

  • text

    Sets the text elements associated with each z value.

  • textsrc

    Sets the source reference on plot.ly for text .

  • transpose

    Transposes the z data.

  • uid

  • 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).

  • x

    Sets the x coordinates.

  • x0

    Alternate to `x`. Builds a linear space of x coordinates. Use with `dx` where `x0` is the starting coordinate and `dx` the step.

  • xaxis

    Sets a reference between this trace's x coordinates and a 2D cartesian x axis. If *x* (the default value), the x coordinates refer to `layout.xaxis`. If *x2*, the x coordinates refer to `layout.xaxis2`, and so on.

  • xcalendar

    Sets the calendar system to use with `x` date data.

  • xsrc

    Sets the source reference on plot.ly for x .

  • xtype

    If *array*, the heatmap's x coordinates are given by *x* (the default behavior when `x` is provided). If *scaled*, the heatmap's x coordinates are given by *x0* and *dx* (the default behavior when `x` is not provided).

  • y

    Sets the y coordinates.

  • y0

    Alternate to `y`. Builds a linear space of y coordinates. Use with `dy` where `y0` is the starting coordinate and `dy` the step.

  • yaxis

    Sets a reference between this trace's y coordinates and a 2D cartesian y axis. If *y* (the default value), the y coordinates refer to `layout.yaxis`. If *y2*, the y coordinates refer to `layout.xaxis2`, and so on.

  • ycalendar

    Sets the calendar system to use with `y` date data.

  • ysrc

    Sets the source reference on plot.ly for y .

  • ytype

    If *array*, the heatmap's y coordinates are given by *y* (the default behavior when `y` is provided) If *scaled*, the heatmap's y coordinates are given by *y0* and *dy* (the default behavior when `y` is not provided)

  • z

    Sets the z data.

  • zauto

    Determines the whether or not the color domain is computed with respect to the input data.

  • zhoverformat

    Sets the hover text formatting rule using d3 formatting mini-languages which are very similar to those in Python. See: https://github.com/d3/d3-format/blob/master/README.md#locale_format

  • zmax

    Sets the upper bound of color domain.

  • zmin

    Sets the lower bound of color domain.

  • zsrc

    Sets the source reference on plot.ly for z .
