BUG:	Use of 'zero' in the option parameter (or ymin=0.) or the 'b' key
	with flux calibrated data causes a plot with limits -0.01 and 0.01
	making the data appear all zero.  The workaround is to set the
	minimum value to a number much smaller than the data but not
	exactly zero.  For example setting ymin=1e-30 when the data
	is around 1e-14.  This plot limit behavior applies to all tasks
	(GRAPH, IMPLOT) but is most likely to appear in SPLOT with flux
	calibrated data.

STATUS:	A change to a system routine is required and has been requested.
