Graphics.Mars.Graph

Description

Use the graph function here to generate the raw graph array data based on various parameters.

Synopsis

Documentation

graph Source

Arguments

:: Int	height (array rows)
-> Int	width (array columns)
-> Float	stamped circle radius
-> Float	jitter factor of walk, usually nearly the same as radius
-> Int	a seed value for the random number generator
-> Int	numbers of steps to take in random walk
-> Float	magnification factor
-> (Float, Float)	starting point
-> IO (UArray (Int, Int) Float)

Beginning in the center, follows a random walk path, and stamps a circle shape onto the array at each step. Internally uses a mutable unboxed array for efficiency, but returns the results in a frozen array.

zRandomize Source

Arguments

:: Float	delta
-> Int	seed value for random number generator
-> UArray (Int, Int) Float	input UArray
-> UArray (Int, Int) Float

Adjust each float value in a UArray by some random value between negative delta and delta.

meldGraphs :: UArray (Int, Int) Float -> UArray (Int, Int) Float -> UArray (Int, Int) Float Source

From each pair of corresponding points on the two input UArrays, select the the higher point, to create a new UArray. The two arrays must have the same bounds, or an error is thrown.
