goog.math.interpolator.Pchip1()A one dimensional monotone cubic spline interpolator.
.computeDerivatives(dx, slope) [protected]Computes the derivative at each point of the spline such that the curve is C2. It uses not-a-knot boundary conditions.
dx {Array.<number>}
slope {Array.<number>}

.getInverse()Inherited from goog.math.interpolator.Spline1 .
Note that the inverse of a cubic spline is not a cubic spline in general. As a result the inverse implementation is only approximate. In particular, it only guarantees the exact inverse at the original input data points passed to setData.
