XY Scatter

criticality

Determines if a combination of difficulty and importance values is critical. Returns a range from 0...4.

Collection criticality(Collection difficulty, Collection importance, float d_crit=3.333333, float i_crit=3.333333)

Parameters

difficulty :	is the difficulty
importance :	is the importance
d_crit :	is the threshold for the critical difficulty
i_crit :	is the threshold for the critical importance

diagramLookup

searches for a maximum or minimum value of items in a diagram defined by a interrelationship matrix

Collection diagramLookup(Collection diagram, Collection src, integer iterations=1.0, boolean findmaximum=true, integer level=nothing)

Parameters

diagram :	is the matrix defining the diagram
src :	is the vector containing the values to be searched
iterations :	defines the number of recursive lookups. Positive numbers indicate a lookup from cause to effect, negative numbers indicate a lookup from effect to cause.
findmaximum :	if true, the result is the maximum of all connected values. if false, the result is the minimum of all connected values.
level :	is the level of details the operation is performed on.

distHyperbolic

returns the value "a" of the hyperbola x*y=(a*a)/2 passing through a given point (x,y).

Collection distHyperbolic(Collection x, Collection y)

Parameters

x :	the value for x
y :	the value for y

distTargetZone

returns a point's distance from a target zone bounded by the two hyperbolas y= sqrt(x*x-q*q) and y= sqrt(x*x+q*q).

Collection distTargetZone(Collection x, Collection y, Collection q)

Parameters

x :	the value for x
y :	the value for y
q :	the hyperbolas' minimum distance q from the origin (0,0).

xySector

Calculates the index of a pair of values within a X-Y-Scatter diagram based on a n x n grid.

Collection xySector(Collection x, Collection y, integer cols=2.0, integer rows=2.0)

Parameters

x :	is the value plotted on the horizontal scale of the diagram.
y :	is the value plotted on the vertical scale of the diagram.
cols :	is the number of grid columns (>1).
rows :	is the number of grid rows (>1)

Result

A column compatible to x and y containing the sector index of each value pair.

Remarks

Sector indices are counted from left to right and bottom up, starting with 1. For a 2 x 2 sector grid, 1 is the left lower sector, 2 is the right lower sector, 3 is the left upper sector, and 4 is the right upper sector.
