Last change on this file since 211 was 211, checked in by srkline, 15 years ago

Several disjoint changes:

1) Threaded the 1D Cylinder_PolyRadius function
2) in Wrapper, popping the data set list now will auto-pop the function, then the coef to properly update the table of coefficients.
3) tick units in the plots are suppressed (y-axis)
4) Killing data (PlotManager?) now kills the dependent variable so that the rest can be killed
5) Ellipsoid_2D function now has the correct notation of the rotation axis in the parameter names.

7// The plotting macro sets up TWO dependencies
8// - one for the triplet calculation
9// - one for a matrix to display, a copy of the triplet
10//
11// For display, there are two copies of the matrix. One matrix is linear, and is a copy of the
12// triplet (which is ALWAYS linear). The other matrix is toggled log/lin for display
13// in the same way the 2D SANS data matrix is handled.
