Graphics.Gnuplot.Value.Tuple
Description
Provide a class that renders multiple Haskell values in a text form that is accessible by gnuplot.
Maybe we add a method for the binary interface to gnuplot later.
- class C a where
- text :: a -> [ShowS]
- columnCount :: ColumnCount a
- newtype ColumnCount a = ColumnCount Int
Documentation
Minimal complete definition
Methods
For values that are also in Atom class,
text
must generate a singleton list.
columnCount :: ColumnCount a Source
It must hold ColumnCount (length (text x)) == columnCount
.
newtype ColumnCount a Source
Count numbers of gnuplot data columns for the respective type.
Somehow a writer monad with respect to Sum monoid without material monadic result.
Cf. ColumnSet module.
