The skip() function would have done the trick too:
set t 1 last
set x 1
set y 1
d skip(var,2)

The following may achieve your desired result -- I used 'q gxinfo' to
get the x and y limits of the plot, which were
Page Size = 11 by 8.5
X Limits = 2 to 10.5
Y Limits = 0.75 to 7.75

Then I used these commands:
'set xlpos -0.4'
'set xlabs k | l | m | n | o '
'set grads off'
'd t'
'set line 0'
'draw recf 1.98 0.27 10.52  0.70'
'set xlpos -0.2'
'set xlabs f | g | h | i | j '
'd t'
'draw recf 1.98 0.47 10.52  0.70'
'set xlpos 0'
'set xlabs a | b | c | d | e '
'set ccolor 1'
'd t'

Where t is a 1-dimensional time series. The labels "a" through "o"
can be modified to suit your needs -- they can have more than one
character and will be centered on each tic mark. The 'draw recf'
commands are to cover up the extra axis line that you don't want to
see. Another option is to use 'draw string' for each line of every
tic label, but that may be more work than the above.
