Pie: Pie chart

In yutannihilation/chartist: Chartist.js for R

Description

The Chartist pie chart can be used to draw pie, donut or gauge charts.

Usage

Pie(width = NULL, height = NULL, chartPadding = NULL, classNames = NULL,
  startAngle = NULL, total = NULL, donut = NULL, donutWidth = NULL,
  showLabel = NULL, labelOffset = NULL, labelInterpolationFnc = NULL,
  labelDirection = NULL, responsiveQuery = NULL)

Arguments

width	fixed width for the chart as a string (i.e. '100px' or '50%')
height	fixed height for the chart as a string (i.e. '100px' or '50%')
chartPadding	padding of the chart drawing area to the container element and labels
classNames	Override the class names that get used to generate the SVG structure of the chart
startAngle	start angle of the pie chart in degrees where 0 points north
total	By specifying a total value, the sum of the values in the series must be this total in order to draw a full pie. You can use this parameter to draw only parts of a pie or gauge charts.
donut	if donut chart or not
donutWidth	donut stroke width
showLabel	if labels should be shown or not
labelOffset	offset of the each label (different from Line() and Bar(), labelOffset must be a single numeric value)
labelInterpolationFnc	JS function to intercept the value from labels
labelDirection	label direction. Possible values are 'neutral', 'explode' or 'implode'.
responsiveQuery	if specified, the options are used only when the query matches.

Examples

## Not run: 
set.seed(324)
data <- data.frame(
  day = 1:20,
  A   = runif(20, 0, 10),
  B   = runif(20, 0, 10),
  C   = runif(20, 0, 10),
  D   = runif(20, 0, 10)
  )

# Only first data series is used for Pie(). So, these two draw the same chart.
interp <- JS_interp(prefix = "Item ")
chartist(data, day) + Pie(labelInterpolationFnc = interp)
chartist(subset(data, , 1), day) + Pie(labelInterpolationFnc = interp)

# responsive chart
chartist(data[1:4, ], day) +
  # by default, draw a donut chart
  Pie(donut = TRUE, donutWidth = 100) +
  # for smaller screens, draw a normal pie chart
  Pie(donut = FALSE, showLabel = FALSE, responsiveQuery = "screen and (max-width: 600px)")

# By default, Chartist knows only four colours
# (c.f. https://github.com/gionkunz/chartist-js/issues/79)
# Corrently Pie() cannot work well with data whose length is more than four
chartist(data, day) + Pie()

## End(Not run)
