No, the column has been extracted as a vector, not a table.

A table line is a list or a symbol, at the point of the error only a
list may be present. However, due to "data" being a vector, you'll get
a number. That's easy enough to guard for in that function, but the bug
is much further up the call chain, most likely in
org-babel-gnuplot-process-vars. Something along the line of the
following patch might be in order:
diff --git a/lisp/ob-gnuplot.el b/lisp/ob-gnuplot.el
index 6783706..7d7db2a 100644
--- a/lisp/ob-gnuplot.el
