That is a very relevant question and I'd be interested in the answer as well. But I am not aware of any support by Org mode for this. I guess calling `org-babel-expand-src-block' prior to tangling would answer your needs? This would be desirable not only for plotting code blocks, also data passed to code block is 'lost' during tangling. I think it would be good to have a source block header argument, say `:tangleexpanded', controlling such functionality. WDYT? Regards, Andreas
