Library "Points" Provides functions for simplifying operations with collections of x+y coordinates. Where x is typically a bar index or time (millisecond) value.
new(size) Creates two arrays. One for X (int[]) and another for Y (float[]). Parameters: size: The initial size of the arrays.
size(xA, yA) Checks the size of the arrays and if they're equal returns the size. Parameters: xA: The X array. yA: The Y array.
get(xA, yA, index) Gets the X and Y values of the arrays at the index. Parameters: xA: The X array. yA: The Y array. index: The index. Returns: [x, y]
set(xA, yA, index, x, y) Sets the X and Y values of the arrays at the index. Parameters: xA: The X array. yA: The Y array. index: The index. x: The x value. y: The y value. Returns: [index, x, y]
push(xA, yA, x, y) Adds X and Y values to the end of the arrays (as the last element). Parameters: xA: The X array. yA: The Y array. x: The x value. y: The y value. Returns: [index, x, y]
unshift(xA, yA, x, y) Adds X and Y values to the beginning of the arrays (as the first element). Parameters: xA: The X array. yA: The Y array. x: The x value. y: The y value. Returns: [index, x, y]
insert(xA, yA, index, x, y) Inserts X and Y values to the arrays at the index. Parameters: xA: The X array. yA: The Y array. index: The index to insert at. x: The x value. y: The y value. Returns: [index, x, y]
pop(xA, yA) Removes the last element from the arrays and returns their value. Parameters: xA: The X array. yA: The Y array. Returns: [x, y]
shift(xA, yA) Removes the first element from the arrays and returns their value. Parameters: xA: The X array. yA: The Y array. Returns: [x, y]
remove(xA, yA) Removes the element from the arrays at the index and returns their value. Parameters: xA: The X array. yA: The Y array. Returns: [x, y]
first(xA, yA) Gets the X and Y values of the first element. Parameters: xA: The X array. yA: The Y array. Returns: [x, y]
last(xA, yA) Gets the X and Y values of the last element. Parameters: xA: The X array. yA: The Y array. Returns: [x, y]
allIndexesBetween(xA, lo, hi, start, ordered) Gets the indexes that have values at or above the low value and below the high value. Parameters: xA: The X array. lo: The inclusive low value. hi: The excluded hi value. start: The optional index to start the backwards search. ordered: If true, the search ends when the first value is found that is less than the low.
lastIndexBetween(xA, lo, hi, start, ordered) Gets the first found from the end that has a value at or above the low value and below the high value. Parameters: xA: The X array. lo: The inclusive low value. hi: The excluded hi value. start: The optional index to start the backwards search. ordered: If true, the search ends when the first value is found that is less than the low.
lastIndexBelow(xA, hi, start) Gets the first found from the end that has a value below the high value. Parameters: xA: The X array. hi: The excluded hi value. start: The optional index to start the backwards search.

v5 Added 'add' method for automatically inserting by X value.
Added: add(xA, yA, x, y) Inserts the X and Y values into the arrays based upon the X value assuming the the arrays is ordered by X. Parameters: xA: The X array. yA: The Y array. x: The x value. y: The y value. Returns: [index, x, y]
