Hi Marvin,

I just tried your example locally, and I also got an empty .eps file.  I
then jumped to the *gnuplot* buffer where I saw the following.

,----
| gnuplot> data = "/tmp/babel-4592fc8/gnuplot-4592Pna"
| gnuplot> set term eps
|                   ^
|          unknown or ambiguous terminal type; type just 'set terminal' for a list
| 
| gnuplot> set output "output.eps"
| gnuplot> set title "test"
| gnuplot> set auto x
| gnuplot> set style data histogram
| gnuplot> set style fill solid border -1
| gnuplot> set boxwidth 0.9
| gnuplot> plot data using 1:2
|               ^
|          use 'set term' to set terminal type first
| 
| gnuplot> 
`----

so if your gnuplot is like my gnuplot then "eps" is not a known terminal
type.  I'd suggest trying the following.  Also, notice that I changed
your "plot" line -- histograms are not intuitive in gnuplot.

#+tblname: gnuplot-testing
| x |  y |
|---+----|
| 1 |  2 |
| 2 |  4 |
| 3 |  6 |
| 4 |  8 |
| 5 | 10 |
| 6 | 12 |
| 7 | 14 |
| 8 | 16 |

#+begin_src gnuplot :var data=gnuplot-testing :file output.eps :exports both
set term postscript
set title "test"
set auto x
set style data histogram
set style fill solid border -1
set boxwidth 0.9
plot data using 2:xtic(1)
#+end_src

Cheers -- Eric
