This first part of my problem was easier than I thought:

(defun grace()
    "Create Plot using grace"
    (interactive)
       (call-process-shell-command (concat (dired-shell-stuff-it "xterm -e 'xmgrace " (dired-get-marked-files) nil) " '&")) 
)

This would plot all marked files ... now I take a look at the <title> and <name>.


Greetings!
