[ gnuplot 4.6 patchlevel 0 ]

trying to understand use of 'set xdata time' vis-a-vis the following points:

I would like to set xrange longer than the available data. I used a "." to mark missing data points. I can plot the first field (see below) using a conventional x/y data setup and various xranges (not shown). however when using 'set xdata time' it appears that this will not work. Note that I have the date in field 2, but this shouldn't matter I think. here are the commands:

gnuplot> set xdata time ; set timefmt '%m-%Y' ; set format x '%b'
gnuplot> plot 'data.dat' u 2:1 w lp

( ... looks OK ...)
            
gnuplot> set xrange [0:14] 
gnuplot> replot           
gnuplot> plot 'data.dat' u 2:1 w lp                                                 
         all points y value undefined!
gnuplot> show xrange

	set xdata time
	set xrange [ * : * ] noreverse nowriteback  # (currently ["10-2011":"05-2012"] )

data.dat:

8.38  11-2011 
1.58  12-2011 
3.13  01-2012 
9.74  02-2012
