It appears to me that the bars of this PDF overlap slightly.  It's as though the bars have lines 
along the outside occupying the same coordinates.  Is there a "no line" option where the inside 
"fill" can go right up against the coordinates as computed by the histogram routine?  Or is that 
what the -1 below does?

        set style fill solid 1.0 border -1

Or should the histogram suggestion be to use "noborder"?  I think that is probably the case because 
the histogram groups in the

  set title "Immigration from different regions\n(give each histogram a separate title)"

demo in histograms.dem looks fairly good.  (It uses "noborder".)

So, maybe change the histogram help documentation to read "noborder" rather than "border -1".  Also, 
I'd suggest "noborder" as the default for solid fill style.  (Or would that be too confusing with a 
fill style that defaults to no fill? In which case, one would want a border to appear.)
