http://www.bersch.net/gnuplot-doc/histograms.html reports that you can use the "at x-coord" option with newhistogram in gnuplots to manually adjust the gap between clusters. I have used a combination of this, the "gap" option for set style histogram and "set offsets " command to move the clusters around on the graph. Hope this helps.

I think you cannot do this with the clustered histogram style, because the gap option takes only integer numbers.

In your case with only two columns, you can use the boxes plotting style and shift the boxes belonging to the first column by half of the boxwidth to the left, and the boxes of the second column by the same amount to the right:

set auto x
set yrange [0:100] 
set style fill solid border -1
boxwidth=0.45

set boxwidth 0.45 absolute
set style data boxes
plot 'test.data' using ($0-boxwidth/2):1, '' u ($0+boxwidth/2):2

Result with 4.6.4:

You are looking for the gap keyword to the set style histogram command.

set style histogram clustered gap <width of gap>
