Dear Thomas, searching on kde-apps.org your new release, I found a reference to Labplot http://www.kde-apps.org/content/show.php?content=9881&PHPSESSID=7cdf5e2fe0371d0442d4d7b5d5e738a8 why don't contact the author and find one way to integrate data manipulation with RKWard and plotting with Labplot?
