Members detail

enum Interpolation

Specifies data interpolation methods. Availability depends on data container used.

Identifier	Description
Nearest	1d and 2d nearest interpolation
Linear	1d linear and 2d bilinear interpolations
Quadratic	1d quadratic interpolation
CubicSimple	1d cubic piecewise interpolation. It has continuous piecewise first derivative, non-continuous piecewise linear second derivative. Use segments slope as first derivative. Less accurate than other cubic interpolants but requires less computation on data set change.
Cubic	1d cubic piecewise interpolation. It has smooth first derivative and continuous piecewise linear second derivative. Derivatives for first and last entries are based on first and last segments slope. It uses linear extrapolation (continuous but non-smooth first derivative on both ends).
Cubic2	Same interpolation as Cubic, with quadratic extrapolation (continous and smooth first derivative on both ends).
CubicDerivInit	Same as Cubic with first derivative prescribed for first and last entries only.
Cubic2DerivInit	Same as Cubic2 with first derivative prescribed for first and last entries only.
CubicDeriv	1d cubic piecewise interpolation. First derivatives must be provided for all entries. It uses linear extrapolation.
Cubic2Deriv	1d cubic piecewise interpolation. First derivatives must be provided for all entries. It uses quadratic extrapolation.
Bicubic	2d bicubic interpolation. Use smooth first derivative and continuous piecewise linear second derivative. Use 1d cubic curve to extract gradients (smooth first derivative and continuous piecewise linear second derivative). This is the best 2d interpolation when derivatives are non-prescribed.
BicubicDiff	2d bicubic interpolation. Use numerical differencing to extract gradients. Less accurate than Bicubic but requires less computation on data set change.
BicubicDeriv	2d bicubic interpolation. x and y gradients must be provided. This is the best 2d interpolation when derivatives values are available.

enum PlotStyleMask

Specifies available styles for 2d and 3d plot data rendering

Identifier	Description
LinePlot	Draw lines between knots
PointPlot	Draw points for each knot
InterpolatePlot	Draw a smooth curve
ValuePlot	Print ploted values near knots
Filled	Draw filled 3d surface
