You don't appear to actually running the histogram demo.  There's no 
command like this in any of the demo files.  Nor would "running the 
demo" have interactive "gnuplot> " prompts.

It doesn't make terribly much sense to combine an explicit "set xtics" 
list with the "xticlabels" option of the "plot" command.

This doesn't seem to reproduce with the (Windows) gnuplot 4.2 
executable.  The most likely reason for this is that whoever built that 
4.2 binary you're using explicitly disabled the histograms compile-time 
option (see "INSTALL").
