Class ExponentialRangeModel

java.lang.Object

javax.swing.DefaultBoundedRangeModel

com.jsyn.swing.DoubleBoundedRangeModel

com.jsyn.swing.ExponentialRangeModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.BoundedRangeModel

public class ExponentialRangeModel
extends DoubleBoundedRangeModel

Maps integer range info to a double value along an exponential scale.

  
   x = ival / resolution
   f(x) = a*(rootˆcx) + b
   f(0.0) = dmin
   f(1.0) = dmax
   b = dmin - a
   a = (dmax - dmin) / (rootˆc - 1)
  
   Inverse function:
   x = log( (y-b)/a ) / log(root)
