BV = swplot.base
swplot.base(BV) sets the basis vector for an swplot figure. The basis
vectors can be used to define a non-orthogonal coordinate system for
swplot.base(obj) sets the basis vectors to the lattice units of a given
BV = swplot.base returns the basis vectors stored in the swplot figure.
- Either a matrix of the new basis vectors or a spinw object where the new basis vectors will be the lattice units and the basis vectors are generated via spinw.basisvector.
- Handle of the [swplot] figure. Default is the active figure.
