pladv: Advance the (sub-)page

Advances to the next subpage if sub=0, performing a page advance if there are no remaining subpages on the current page. If subwindowing isn't being used, pladv(0) will always advance the page. If sub>0, PLplot switches to the specified subpage. Note that this allows you to overwrite a plot on the specified subpage; if this is not what you intended, use pleop followed by plbop to first advance the page. This routine is called automatically (with sub=0) by plenv, but if plenv is not used, pladv must be called after initializing PLplot but before defining the viewport.

sub (PLINT, input) Specifies the subpage number (starting from 1 in the top left corner and increasing along the rows) to which to advance. Set to zero to advance to the next subpage.
