Typical bar chart options.

The internal model for a bar chart (across the x-axis for a vertical bar chart) is:

• half the outerGap at the start and the end.
• each row collection of bars, including the outerGap and innerGaps has a value of 1.
• the entire x range of the chart isequal to the number of rows in the bar data.
• The value of inner and outer gaps are relative to this model.

>>> let barDataExample = BarData [[1, 2, 3, 5, 8, 0, -2, 11, 2, 1], [1 .. 10]] (("row " <>) . pack . show <$> [1 .. 11]) (("column " <>) . pack . show <$> [1 .. 2])
>>> let barExample = barChart defaultBarOptions barDataExample

The official bar options.

Two dimensional data, maybe with row and column labels.

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

A bar chart without hud trimmings.

>>> bars defaultBarOptions (BarData [[1,2],[2,3]] [] [])

A bar chart.

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

Make bars from the double list values, normalizing to one :: Rect.

>>> barRects defaultBarOptions [[1,2],[2,3]]

>>> barRects defaultBarOptions [[]]

Placed text, hold the bars.
