The Plot menu implements a rudimentary plotting option in O. The Plot command generates an O descriptor language description of the objects to be plotted together with keywords describing scale and orientation information. These may require fine tuning before making the final plots. This file can be converted into a POSTSCRIPT file using the program oplot. The semi-transparent maps can not currently be plotted, but sketches and CPK's can. With a suitable printer, coloured drawings can be plotted. Refer to section 8.7 for further information.
