Starting PLPLOT

Subroutine plstar selects a graphics device or opens a disk file to receive a plot for later display. If plstar is called again during a program, the previously opened file will be closed. When called, the user is prompted for a number representing the device on which the plot is to appear. The syntax for plstar is:

plstar(nx,ny); nx, ny (int, input) The number of plots to a page. The page is divided into nx × ny subpages, with nx in the horizontal direction, and ny in the vertical direction.

Subpages are useful for placing several graphs on a page, but all subpages are constrained to be of the same size. For greater flexibility in placing graphs on a page, read page in Section which discusses viewports.
