NAME

Chart::Plotly::Trace::Bar - The data visualized by the span of the bars is set in `y` if `orientation` is set th *v* (the default) and the labels are set in `x`. By setting `orientation` to *h*, the roles are interchanged.

SYNOPSIS

                                              y    => [ map { int( rand() * 10 ) } ( 1 .. ( scalar(@$x) ) ) ],

DESCRIPTION

The data visualized by the span of the bars is set in `y` if `orientation` is set th *v* (the default) and the labels are set in `x`. By setting `orientation` to *h*, the roles are interchanged.

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

• base

  Sets where the bar base is drawn (in position axis units). In *stack* or *relative* barmode, traces that set *base* will be excluded and drawn in *overlay* mode instead.

• basesrc

  Sets the source reference on plot.ly for base .

• cliponaxis

  Determines whether the text nodes are clipped about the subplot axes. To show the text nodes above axis lines and tick labels, make sure to set `xaxis.layer` and `yaxis.layer` to *below traces*.

• constraintext

  Constrain the size of text inside or outside a bar to be no larger than the bar itself.

• 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.

• error_x

• error_y

• 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

• hovertext

  Sets hover text elements associated with each (x,y) pair. 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. To be seen, trace `hoverinfo` must contain a *text* flag.

• 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 .

• insidetextfont

• 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

• name

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

• offset

  Shifts the position where the bar is drawn (in position axis units). In *group* barmode, traces that set *offset* will be excluded and drawn in *overlay* mode instead.

• offsetsrc

  Sets the source reference on plot.ly for offset .

• opacity

  Sets the opacity of the trace.

• orientation

  Sets the orientation of the bars. With *v* (*h*), the value of the each bar spans along the vertical (horizontal).

• outsidetextfont

• r

  For legacy polar chart only.Please switch to *scatterpolar* trace type.Sets the radial coordinates.

• rsrc

  Sets the source reference on plot.ly for r .

• 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.

• stream

• t

  For legacy polar chart only.Please switch to *scatterpolar* trace type.Sets the angular coordinates.

• text

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

• textfont

• textposition

  Specifies the location of the `text`. *inside* positions `text` inside, next to the bar end (rotated and scaled if needed). *outside* positions `text` outside, next to the bar end (scaled if needed). *auto* positions `text` inside or outside so that `text` size is maximized.

• textpositionsrc

  Sets the source reference on plot.ly for textposition .

• textsrc

  Sets the source reference on plot.ly for text .

• tsrc

  Sets the source reference on plot.ly for t .

• uid

• 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).

• width

  Sets the bar width (in position axis units).

• widthsrc

  Sets the source reference on plot.ly for width .

• 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 .

• 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 .
