Hi Mike, I have done this in Ferret (assuming I understand your problem).

Is it possible with Ferret or pplus to plot two time series variables each with their own vertical axis on the same horizontal axis? -Mike -- Mike McCann Software Engineer Monterey Bay Aquarium Research Institute 7700 Sandholdt Road Moss Landing, CA 95039-9644 Voice: 831.775.1769 Fax: 831.775.1736 http://www.mbari.org <http://www.mbari.org/>======================================================= Stephen R.
