Normally plots are auto-sized by reveal but if they are initially hidden the can't be (as reveal actually measures the DOM size as part of its auto-sizing). In this case you need to manually size the plot.

yes, stretch feature and fragment in revealjs does not work together. For reference, related to #816 and upstream hakimel/reveal.js#1840
