I am reworking the gnuplot script, it is not done at this point, but this is what I currently have:
#+begin_src gnuplot :var data="" :file org-running.png :exports both
set title "Running Stats"
set xtics nomirror rotate by -45
set key noenhanced
set style data linespoints
plot "$data" using 2:xtic(1) title columnheader(1), \
for [i=2:3] '' using i title columnheader(i)
#+end_src

Nick,
This got me curious to see the output. I tried to generate it on my computer and get this in the *gnuplot* buffer after running the code:
-----
gnuplot> plot data using 1:2:3 notitle
^
warning: Skipping data file with no valid points
^
x range is invalid

This is working for you, though?

set title "Running Stats"
set auto x
set style data histogram
set style fill solid border -1
set boxwidth .9

plot data using 1:2:3 notitle

Erik,
That was the issue, the :file reference needed to be on the line above. Thanks.

Hi John,
I would actually like to plot different lines per distance, each
that correlate to a date and elapsed-time (x and y axis respectively).
I get an error with the :file notation, though I read that in a sample
babel gnuplot example for generating graphs of commit history on the
org-mode git repository. I tried to reference the variable data without
the quotes and $ sign without any success. I will continue to fiddle
with it, I am new to gnuplot.
AFAIK, you can't break source code header argument lines across
multiple lines. Is that how you actually have it in your
org file?
#+begin_src gnuplot :var data="">
:file org-running.png :exports both
set title "Running Stats"
set auto x
set style data histogram
set style fill solid border -1
set boxwidth .9
set xlabel "Date"
set ylabel "Time"
plot "$data" using 1:2:3 notitle
#+end_src
