This is primarily used internally whenever the list of things ; overplotted on the main data container is changed (e.g. vline, ; annotate, gbtoplot, oshow, etc). However, it is also useful to users ; in two circumstances. If you have killed the plotter window by ; clicking on the appropriate frame decoration in your display then ; reshow will cause it to reappear exactly as it was before. It is ; also useful if you want to string together several vline or annotate ; calls before updating the plotter (using the /noshow argument in ; each call). This can greatly speed up that operation. ; ; @examples ;
