First of all, I do believe it would be good to move the plotting
settings to outside the table, either before or after.

I can see good ways to specify parameters for a plot that would be quite
consistent with how Org deals with such things in similar situations.

1. A special comment line in the buffer, directly before the table, like

#+PLOT: table-to-gnuplot :xcol 1 :ycols (2 4 5 6) :title "Some string"

or

#+PLOT: table-to-R :script "/path/to/script"

The command can read these by macthing

(if (looking-at "#+PLOT: +\\([^ \t\r\n]+\\)\\( +.*\\)?")
     (let* ((func (intern (match-string 1)))
	   (params-plist
	    (if (match-end 2)
		(read (concat "(" (match-string 2 format) ")")))))

2. Use inherited properties to specify plotting parameters in a tree.
