piechart

piechart(x::VecOrMat; kw...)

Create a pie chart of the values in the vector data x.

Each slice has a label indicating its size as a percentage of the whole pie or a label provided by the user.

Args

• x: Slice data, specified as a vector of numeric values. The size of each slice is a percentage of the whole pie, depending on the sum of the elements of data:

  • If sum(data) < 1, the values of data specify the areas of the pie slices, and the result is a partial pie.
  • If sum(data) ≥ 1, the data values are normalized by data/sum(data) to determine the area of each slice of the pie.

Kwargs

• colors: - A sequence of comma separated colors through which the pie chart will cycle. By default we use the cycle colors.

• explode: - Offset slices, specified as a Int or logical vector. Slice numbers specified in this option are exploded with a shift of 4% of the pie diameter. Example: explode=2 will explode slice 2. explode=[2,4] will explode slices 2 and 4.

• font: The fontsize used in labels. By default we compute onde from the pie size (see \(ms\) below), but user can specify a fontsize in points (and optionally a font name and color).

• labels: - A string vector or a tuple with the labels of each slice.

• labelstyle: - Label style, specified as one of the values in the next list.

  • "namepercent": - Display the \(labels\) and proportions values (as percentages) next to the corresponding slices.
  • "namedata": - Labels with the name and value of each slice.
  • "name": - Display the \(labels\) values next to the corresponding slices.
  • "data": - Display the Data values next to the corresponding slices.
  • "percent": - Display the proportions values (as percentages) next to the corresponding slices (the defaul when no \(labels\) are provided).
  • "none": - Do not display any labels.

• ms or markersize: - The diameter of the pie in cm (Default is 8 cm).

Example

piechart([1,2,3,4], explode=2, labels=("A","B","C","D"), labelstyle="namepercent", show=true)
