Tells SPECX that you have no further use for the currently opened plot file. Thus after doing this it is no longer possible to ``preview'' the plot using SEE-PLOT, nor to add further spectra to the existing plot using OVERLAY-SPECTRUM.
For plotting to a hardcopy device, this causes the final plot to be sent to the device.
CLOSE-PLOT is implicit in a NEW-PLOT, whatever the graphics device, and is also called on EXIT from SPECX.
Examples:
>> close-plot<CR>
