BUG:	The 'a' key for expanding a region with y scaling based on the
	values in the selected region can be wrong if the dispersion is
	non-linear.  This is because the inversion from dispersion
	coordinate to pixel is done assuming a linear dispersion.  The
	symptom is that the y scale will not cover the data.  If the data
	is sufficiently sloped and the dispersion sufficiently non-linear
	it is possible the graph window will be outside the range of the
	data yielding an empty plot.  The workaround is to use the 'w'
	windowing keys such as 'e'.

STATUS:	Fixed for the next release.
