3D-plotting in a four-variable system (Quatplot)

Enables 3D-plotting in a tetrahedron

Info: This function allows 3D-plotting in a four-component system (tetrahedron). The interpretation of the data is facilitated by the usage of integrated subfields. Annotations and dimensions of the subfields can easily be adapted in the function. With regard to the dimension of the subfields, an excel spreadsheet for the calculation of the XYZ coordinates is attached.
