Usage

v_gauge(
  vc,
  mapping = NULL,
  data = NULL,
  name = NULL,
  outerRadius = 0.8,
  innerRadius = 0.75,
  startAngle = -240,
  endAngle = 60,
  ...,
  serie_id = NULL,
  data_id = NULL
)

Value

A vchart()

htmlwidget object.

Arguments

vc

A chart initialized with vchart().

mapping

Default list of aesthetic mappings to use for chart.

data

Default dataset to use for chart. If not already a data.frame, it will be coerced to with as.data.frame.

name

Name for the serie, only used for single serie (no color/fill aesthetic supplied).

outerRadius

Sector outer radius, with a numerical range of 0 - 1.

innerRadius

Sector inner radius, with a numerical range of 0 - 1.

startAngle

Starting angle of the sector. In degrees.

endAngle

Ending angle of the sector. In degrees.

...

Additional parameters for the serie.

data_id, serie_id

ID for the data/serie, can be used to further customize the chart with v_specs().

Examples

vchart() %>%
  v_gauge(aes("My gauge", 0.8))

vchart() %>%
  v_gauge(

    gauge = list(
      type = "circularProgress",
      cornerRadius = 20,
      progress = list(
        style = list(
          fill = "forestgreen"
