// CHANGES to 'JSVPanel.java'
// University of the West Indies, Mona Campus
//
// 25-06-2007 rjl - bug in ReversePlot for non-continuous spectra fixed
//                - previously, one point less than npoints was displayed
// 25-06-2007 cw  - show/hide/close modified
// 10-02-2009 cw  - adjust for non zero baseline in North South plots
// 24-08-2010 rjl - check coord output is not Internationalised and uses decimal point not comma
// 31-10-2010 rjl - bug fix for drawZoomBox suggested by Tim te Beek
// 01-11-2010 rjl - bug fix for drawZoomBox
// 05-11-2010 rjl - colour the drawZoomBox area suggested by Valery Tkachenko
// 23-07-2011 jak - Added feature to draw the x scale, y scale, x units and y units
//					independently of each other. Added independent controls for the font,
//					title font, title bold, and integral plot color.
// 24-09-2011 jak - Altered drawGraph to fix bug related to reversed highlights. Added code to
//					draw integration ratio annotations
// 03-06-2012 rmh - Full overhaul; code simplification; added support for Jcamp 6 nD spectra
