C3 Pie Charts — c3pie • c3plot

Draw an interactive pie chart using 'C3.js'

Usage

c3pie(
  x,
  labels = names(x),
  col = NULL,
  slice.text = "pct",
  legend.position = "right",
  main = NULL,
  width = NULL,
  height = NULL,
  elementId = NULL
)

Arguments

x: a vector of non-negative numerical quantities. The values in x are displayed as the areas of pie slices.
labels: character vector giving names for the slices.
col: character vector of colors to be used in filling the slices. Can be a hex value or an R built-in color name.
slice.text: "pct" to display percentage-formatted values inside pie slices (default c3.js behavior) or "id" to display the slice's name from labels (note that this does not change labels' positioning within their slices, so using slize.text = "id" may result in poorly-placed or cut-off slice labels)
legend.position: Position of the legend. Possible values are "right", "bottom", "inset", and "hide".
main: a main title for the plot.
width: width of the widget to create for the plot. The default is NULL, which results in automatic resizing based on the plot's container.
height: height of the widget to create for the plot. The default is NULL, which results in automatic resizing based on the plot's container.
elementId: Use an explicit element ID for the widget, rather than an automatically generated one.

Examples


pie.sales <- c(0.12, 0.3, 0.26, 0.16, 0.04, 0.12)
names(pie.sales) <- c("Blueberry", "Cherry",
                    "Apple", "Boston Cream", "Other", "Vanilla Cream")
c3pie(pie.sales)

c3pie(pie.sales, col = c("purple", "violetred1", "green3",
                      "cornsilk", "cyan", "white"))
