That would be seriously difficult, given that for at least some plots, 
these values don't even exist other than during the execution of a 
'plot' or 'splot' command.

If you want to access those variables, I'm afraid the only sensible way 
is to do it the other way round: invent your own variable names for 
these, and issue commands to set the gnuplot state according to them, i.e.

	set xrange [my_xleft:my_xright]

Align them --- to _what_?  Have you read and understood 'help coordinates'?
