8// procedures to plot the sma, emp, and cor data
9// - user interaction is through control bar on COR_Graph
10// - provides user with feedback about peak angle, transmissions
11// - asks for information about BKG and EMP levels
12// - asks for sample thickness
13// - interactively selects range of data to save (and type)
14// - dispatches to routines to determine transmissions and correct the data
15// - dispatches to save routines

20//plot all that is available in the root:Graph folder
21// no distinction as to what the status of the data really is
22// "Clr" buttons on the USANS_Panel will clear the graph..
