Ansigraph is an ultralightweight terminal-based graphing utility. It uses
Unicode characters and ANSI escape codes to display and animate colored graphs
of vectors/functions in real and complex variables.
This functionality is provided by a 'Graphable' type class, whose method
'graphWith' draws a graph at the terminal. Another function 'animateWith' takes
a list of Graphable elements and displays an animation by rendering them in
sequence. Both of these functions take an options record as an argument.
The 'graph' and 'animate' functions are defined to use the default options, and
the user can define similar functions based on their own settings.
There are two main ways to use the package. Importing
"System.Console.Ansigraph" provides all the functionality we typically use.
This includes the /FlexibleInstances/ extension, which makes it marginally more
convenient to use graphing functions by allowing instances like 'Graphable
If you want to use the package without activating /FlexibleInstances/ then you
can import "System.Console.Ansigraph.Core", which provides everything except
these instances. Then you must use one of a few newtype wrappers, namely:
'Graph', 'PosGraph', 'CGraph', 'Mat', 'CMat'. These wrappers are also available
from the standard 'Ansigraph' module.
The "System.Console.Ansigraph.Examples" module contains examples of all the
graph types, and also shows the available ANSI colors.
