## Set the current plot window to plot window n or creates a new figure,
## returning the window id and driver;
## If the driver is tk, also returns its interpreter name
## If device is specified, it is opened. Default is 'xwin'.
## If file is specified, it is passed to PLplot for use. Can be a real file for
## plot output (e.g. postscript), or a Xserver DISPLAY name.
## If win_id is specified, the plot will use the X window identified by win_id
## if the driver is "xwin". Use program `xwininfo' to get its hexadecimal id
## and octave `hex2dec' to get its decimal id.
##
## For use with an external .tcl script:
##
## If tk_file is specified, the tk driver executes this file. In this case,
## where tk_file tipically draws a tk GUI, plot_frame should be the name of
## an empty frame where the actual plot will take place.
##
## if file == "" or win_id == 0 no action is taken for this arguments.
