SYNOPSIS

zw

DESCRIPTION

Complex plots that incorporate multiple data sets, windows, annotations, etc. should be created by entering zw before the drawing commands. This keeps the graphics device open while you build the plot. Although window graphics displays such as those on workstations allow you to add elements to the display of the plot without using zw,the command is essential if the plot is being sent to a printer. When all elements of the plot have been drawn, a close-filter command, zx or zs,is used to complete the plot.

When zw is used in conjunction with printing devices, the plot will not be sent to the printer until a close-filter command is issued. Likewise, display terminals that have distinct graphics and text modes will remain in graphics mode.

When a filter is kept open using zw,it will stay open until a zx or zs command is entered, another filter is initialized with the zi command or you exit C-PLOT

For general information on graphics filters, see the filters help file.
