I think what you want to do is to keep your polar plot display in a
subVI. The subVI window shouldn't need to be open. You can either set
the Print on Completion option on the VI Settings, or you can use the VI
Server t
o invoke the Print method. You will probably want this to be on
the subVI panel and call it with data and parameters telling it if it
should print. The print method is VI class, and is called Print Panel
To Printer. The Entire panel determines if it clips to the visible
portion or includes controls that are scrolled off. If you have
problems with this, it is probably because LV has decided that the panel
doesn't need to be loaded into memory if it isn't open. LV has to make
an informed guess on this, and the easiest way to persuade it is to make
a property node for some control on the subVI, set it to read, and add a
comment saying why it is there.
