\section{Computed variables}{

The following computed variables are available via \code{after_stat()}:
\itemize{
\item \code{x}, \code{y}, \code{z}: Grid coordinates and function values
\item \code{normal_x}, \code{normal_y}, \code{normal_z}: Surface normal components
\item \code{slope}: Gradient magnitude from surface calculations
\item \code{aspect}: Direction of steepest slope from surface calculations
\item \code{dzdx}, \code{dzdy}: Partial derivatives from surface calculation
}
