hoption doesn't enable to flow figure to available space. better is to usehtb, which enable, that float is moved to top of the next page (if at point of insertion is not enough space for it) or to bottom of the same page. otherwise it can happen that float be pushed to the end of document. – Zarko Apr 26 '19 at 05:36
