SYNOPSIS

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

my $cone = Chart::Plotly::Trace::Cone->new(
                x => [1, 2],
                y => [1, 2],
                z => [1, 2],
                u => [1, 2],
                v => [1, 2],
                w => [1, 2]

DESCRIPTION

Use cone traces to visualize vector fields. Specify a vector field using 6 1D arrays, 3 position arrays `x`, `y` and `z` and 3 vector component arrays `u`, `v`, `w`. The cones are drawn exactly at the positions given by `x`, `y` and `z`.

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

• anchor

  Sets the cones' anchor with respect to their x/y/z positions. Note that *cm* denote the cone's center of mass which corresponds to 1/4 from the tail to tip.

• autocolorscale

  Determines whether the colorscale is a default palette (`autocolorscale: true`) or the palette determined by `colorscale`. In case `colorscale` is unspecified or `autocolorscale` is true, the default palette will be chosen according to whether numbers in the `color` array are all positive, all negative or mixed.

• cauto

  Determines whether or not the color domain is computed with respect to the input data (here u/v/w norm) or the bounds set in `cmin` and `cmax` Defaults to `false` when `cmin` and `cmax` are set by the user.

• cmax

  Sets the upper bound of the color domain. Value should have the same units as u/v/w norm and if set, `cmin` must be set as well.

• cmin

  Sets the lower bound of the color domain. Value should have the same units as u/v/w norm and if set, `cmax` must be set as well.

• 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 color space, use`cmin` and `cmax`. Alternatively, `colorscale` may be a palette name string of the following list: Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu,Reds,Blues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,Earth,Electric,Viridis,Cividis.

• 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 .

• 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.

• lighting

• lightposition

• name

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

• opacity

  Sets the opacity of the surface.

• reversescale

  Reverses the color mapping if true. If true, `cmin` will correspond to the last color in the array and `cmax` will correspond to the first color.

• scene

  Sets a reference between this trace's 3D coordinate system and a 3D scene. If *scene* (the default value), the (x,y,z) coordinates refer to `layout.scene`. If *scene2*, the (x,y,z) coordinates refer to `layout.scene2`, and so on.

• 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.

• sizemode

  Determines whether `sizeref` is set as a *scaled* (i.e unitless) scalar (normalized by the max u/v/w norm in the vector field) or as *absolute* value (in the same units as the vector field).

• sizeref

  Adjusts the cone size scaling. The size of the cones is determined by their u/v/w norm multiplied a factor and `sizeref`. This factor (computed internally) corresponds to the minimum "time" to travel across two successive x/y/z positions at the average velocity of those two successive positions. All cones in a given trace use the same factor. With `sizemode` set to *scaled*, `sizeref` is unitless, its default value is *0.5* With `sizemode` set to *absolute*, `sizeref` has the same units as the u/v/w vector field, its the default value is half the sample's maximum vector norm.

• stream

• text

  Sets the text elements associated with the cones. If trace `hoverinfo` contains a *text* flag and *hovertext* is not set, these elements will be seen in the hover labels.

• textsrc

  Sets the source reference on plot.ly for text .

• u

  Sets the x components of the vector field.

• uid

• 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.

• usrc

  Sets the source reference on plot.ly for u .

• v

  Sets the y components of the vector field.

• 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).

• vsrc

  Sets the source reference on plot.ly for v .

• w

  Sets the z components of the vector field.

• wsrc

  Sets the source reference on plot.ly for w .

• x

  Sets the x coordinates of the vector field and of the displayed cones.

• xsrc

  Sets the source reference on plot.ly for x .

• y

  Sets the y coordinates of the vector field and of the displayed cones.

• ysrc

  Sets the source reference on plot.ly for y .

• z

  Sets the z coordinates of the vector field and of the displayed cones.

• zsrc

  Sets the source reference on plot.ly for z .
