In gnuplot-4.2 or after, I found that the command "set xtics 
<incr>" has no effect when "xticlabels(n)" is used.

For example The commands

 plot 'data' using 0:2:xtic(1) with lp

for the data

 01/03 10
 01/04 20
 01/05 15
 ....

makes labels at every x=0,1,2,... and they are overlap each other.

In the case without xtic(1), we may use "set xtics <incr>" to 
avoid it:

 set xtics 5
 plot 'data' using 0:2 with lp

This makes skipped labels at x=0,5,10,... But with xtic(1), "set 
xtics 5" has no effect:

 set xtics 5
 plot 'data' using 0:2:xtic(1) with lp

This makes labels at every x=0,1,2,...
