barDataLowerUpper :: Stacked -> [[Double]] -> [[(Double, Double)]] Source #

Convert data to a range assuming a zero bound (a very common but implicit assumption in a lot of bar charts)

>>> barDataLowerUpper NonStacked [[1,2],[2,3]]
[[(0.0,1.0),(0.0,2.0)],[(0.0,2.0),(0.0,3.0)]]

barRange :: [[Double]] -> Rect Double Source #

Calculate the Rect range of a bar data set.

>>> barRange [[1,2],[2,3]]
Rect 0.0 2.0 0.0 3.0
>>> barRange [[]]
Rect -0.5 0.5 -0.5 0.5

bars :: BarOptions -> BarData -> [Chart] Source #

A bar chart without hud trimmings.

>>> bars defaultBarOptions (BarData [[1,2],[2,3]] [] [])
[RectChart (RectStyle {borderSize = 5.0e-3, borderColor = Colour 0.02 0.29 0.48 1.00, color = Colour 0.02 0.29 0.48 0.70}) [Rect 5.0e-2 0.5 0.0 1.0,Rect 1.05 1.5 0.0 2.0],RectChart (RectStyle {borderSize = 5.0e-3, borderColor = Colour 0.66 0.07 0.55 1.00, color = Colour 0.66 0.07 0.55 0.70}) [Rect 0.5 0.95 0.0 2.0,Rect 1.5 1.95 0.0 3.0],BlankChart [Rect -5.0e-2 2.05 0.0 3.0]]
>>> bars defaultBarOptions (BarData [[]] [] [])
[]

barChart :: BarOptions -> BarData -> ChartSvg Source #

A bar chart.

>>> emptyBar = barChart defaultBarOptions (BarData [] [] [])
>>> foldOf (#charts % charts') emptyBar
[]

barRects :: BarOptions -> [[Double]] -> [[Rect Double]] Source #

Convert BarData to Rects

>>> barRects defaultBarOptions [[1,2],[2,3]]
[[Rect 5.0e-2 0.5 0.0 1.0,Rect 1.05 1.5 0.0 2.0],[Rect 0.5 0.95 0.0 2.0,Rect 1.5 1.95 0.0 3.0]]
>>> barRects defaultBarOptions [[]]
