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 radial axis units). In *stack* barmode, traces that set *base* will be excluded and drawn in *overlay* mode instead.

  • basesrc

    Sets the source reference on plot.ly for base .

  • 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 .

  • dr

    Sets the r coordinate step.

  • dtheta

    Sets the theta coordinate step. By default, the `dtheta` step equals the subplot's period divided by the length of the `r` coordinates.

  • 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.

  • marker

  • name

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

  • offset

    Shifts the angular position where the bar is drawn (in *thetatunit* units).

  • offsetsrc

    Sets the source reference on plot.ly for offset .

  • opacity

    Sets the opacity of the trace.

  • r

    Sets the radial coordinates

  • r0

    Alternate to `r`. Builds a linear space of r coordinates. Use with `dr` where `r0` is the starting coordinate and `dr` the step.

  • 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

  • subplot

    Sets a reference between this trace's data coordinates and a polar subplot. If *polar* (the default value), the data refer to `layout.polar`. If *polar2*, the data refer to `layout.polar2`, and so on.

  • text

    Sets hover text elements associated with each bar. If a single string, the same string appears over all bars. If an array of string, the items are mapped in order to the this trace's coordinates.

  • textsrc

    Sets the source reference on plot.ly for text .

  • theta

    Sets the angular coordinates

  • theta0

    Alternate to `theta`. Builds a linear space of theta coordinates. Use with `dtheta` where `theta0` is the starting coordinate and `dtheta` the step.

  • thetasrc

    Sets the source reference on plot.ly for theta .

  • thetaunit

    Sets the unit of input *theta* values. Has an effect only when on *linear* angular axes.

  • transforms

  • 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.

  • 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 angular width (in *thetaunit* units).

  • widthsrc

    Sets the source reference on plot.ly for width .
