// The plotting macro sets up TWO dependencies
// - one for the triplet calculation
// - one for a matrix to display, a copy of the triplet
//
// For display, there are two copies of the matrix. One matrix is linear, and is a copy of the 
// triplet (which is ALWAYS linear). The other matrix is toggled log/lin for display
// in the same way the 2D SANS data matrix is handled.
//

///  REQUIRES DANSE XOP for 2D FUNCTIONS

//
// the calculation is done as for the QxQy data set:
// three waves XYZ, then converted to a matrix
