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
