If you e.g. zoom it opens a new stream and plots the "new" data. So I take care of the data (in your case which points are shown and which not) above the PLplot level. PLplot doesn't allow to zoom or pan data (which was important to me), so the only solution was to do it this way. PLplot doesn't remember the data, only what it plotted (in a buffer).
