defaultBarOptions :: BarOptions Source #

The official bar options.

data BarData Source #

imagine a dataframe you get in other languages:

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

Constructors

BarData

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)

barChart :: BarOptions -> BarData -> (HudOptions, [Chart Double]) Source #

A bar chart with hud trimmings.

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