selecting the data points by changing the xrange
is not the appropriate way to go - the 'every'
option of the plot command should be used instead:

set xrange [0:1100]
plot 'temp.dat' using 1:2 every 1::0::0 with linespoints
plot 'temp.dat' using 1:2 every 1::0::1 with linespoints
plot 'temp.dat' using 1:2 every 1::0::2 with linespoints
...
