defaultBarOptions :: BarOptions Source #

The official bar options.

data BarData Source #

imagine a dataframe you get in other languages:

definitely some [[Double]]
maybe some row names
maybe some column names

barDataLowerUpper :: Bool -> [[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 False [[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

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

A bar chart without hud trimmings.

>>> bars defaultBarOptions (BarData [[1,2],[2,3]] Nothing Nothing)
[Chart {annotation = RectA (RectStyle {borderSize = 2.0e-3, borderColor = Colour 0.69 0.35 0.16 1.00, color = Colour 0.69 0.35 0.16 1.00}), xys = [R 5.0e-2 0.45 0.0 1.0,R 1.05 1.4500000000000002 0.0 2.0]},Chart {annotation = RectA (RectStyle {borderSize = 2.0e-3, borderColor = Colour 0.65 0.81 0.89 1.00, color = Colour 0.65 0.81 0.89 1.00}), xys = [R 0.45 0.8500000000000001 0.0 2.0,R 1.4500000000000002 1.85 0.0 3.0]},Chart {annotation = BlankA, xys = [R -5.0e-2 1.9500000000000002 0.0 3.0]}]

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

A bar chart.

By convention only, the first axis (if any) is the bar axis.
