JavaScript Figure Reference: indicator Traces

A indicator trace is an object with the key "type" equal to "indicator" (i.e. {"type": "indicator"}) and any of the keys listed below.

An indicator is used to visualize a single `value` along with some contextual information such as `steps` or a `threshold`, using a combination of three visual elements: a number, a delta, and/or a gauge. Deltas are taken with respect to a `reference`. Gauges can be either angular or bullet (aka linear) gauges.

  • type
    Parent: data[type=indicator]
    Type: "indicator"
  • name
    Parent: data[type=indicator]

    • align
      Parent: data[type=indicator].title
      Type: enumerated , one of ( "left" | "center" | "right" )

        HTML font family - the typeface that will be applied by the web browser. The web browser can only apply a font if it is available on the system where it runs. Provide multiple font families, separated by commas, to indicate the order in which to apply fonts if they aren't available.

      • lineposition
        Parent: data[type=indicator].title.font

  • legend
    Parent: data[type=indicator]
    Type: subplotid
    Default: legend

    Sets the reference to a legend to show this trace in. References to these legends are "legend", "legend2", "legend3", etc. Settings for these legends are set in the layout, under `layout.legend`, `layout.legend2`, etc.

    Sets the legend rank for this trace. Items and groups with smaller ranks are presented on top/left side while with "reversed" `legend.traceorder` they are on bottom/right side. The default legendrank is 1000, so that you can use ranks less than 1000 to place certain items before all unranked items, and ranks greater than 1000 to go after all unranked items. When having unranked or equal rank items shapes would be displayed after traces i.e. according to their order in data and layout.
