A pie plot is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.
(see piePlot
example for code to make this plot)

:: (MonadState (Axis b Polar n) m, Plotable (Wedge n) b, Foldable f) | |
=> f a | data for each wedge |
-> (a -> n) | extract weight of each wedge |
-> State (PieState b n a) () | |
-> m () |
Make a pie plot from a list of data by making a series of wedge plots.
Example
import Plots pieData = [("red", 3), ("blue", 4), ("green", 2), ("purple", 5)] piePlotAxis :: Axis B Polar Double piePlotAxis = polarAxis &~ do piePlot pieData snd $ wedgeKeys fst hide (axes . traversed)
piePlotExample = renderAxis piePlotAxis
:: (MonadState (Axis b Polar n) m, Plotable (Wedge n) b, Foldable f) | |
=> f n | weight of each wedge |
-> m () |
Make a pie plot from list of values without any changes.
Example
import Plots piePlotAxis' :: Axis B Polar Double piePlotAxis' = polarAxis &~ do piePlot' [1,3,5,2] wedgeInnerRadius .= 0.5 hide (axes . traversed)
pieExample' = renderAxis piePlotAxis'
onWedges :: (a -> State (Plot (Wedge n) b) ()) -> State (PieState b n a) () Source #
Modify the state for each wedge given the data entry.
Some common lenses to use on the Wedge
:
plotColour
- change the colour of the barsareaStyle
- modify the style of the barskey
- add a legend entry for that group of barswedgeOffset
- the offset of the wedge from the center
wedgeKeys :: Num n => (a -> String) -> State (PieState b n a) () Source #
Add a legend entry for each item given a function that extracts the item's name.
Wedges
Contains information to draw a single wedge of a pie. It is not
intended to be drawn directly. Instead use piePlot
.
