Pie chart

using InMemoryDatasets, StatisticalGraphics, DLMReader

Pie chart shows the frequency of category in a data set as proportional slices of a whole circle

sgplot(Dataset(x=[1,2,3,3,4,4,4]),
             Pie(category=:x)
       )

Users can pass a column as response for computing the slices based on the aggregated values of the passed column. The stat keyword argument is used to aggregate the values.

cars = filereader(joinpath(dirname(pathof(StatisticalGraphics)),
                                 "..", "docs", "assets", "cars.csv"),
                                 types=Dict(9=>Date))


sgplot(cars,
            Pie(category=:Origin, response=:Acceleration, stat=IMD.mean)
        )

A column can be passed as group to produce a nested pie chart

sgplot(cars,

            Pie(category=:Cylinders,
                group=:Origin,
                groupspace=0.05,
                )
    )

The donut chart is produced by passing innerradius

sgplot(cars,
            Pie(category=:Origin, innerradius=0.4)
        )

Slices can be labeled based on their frequency and/or category

sgplot(cars,
            Pie(category=:Origin, label=:both)
        )
