    this question came to me recently. I told jim about
    NCL and the new 2d plotting capability.

    1) is there anything about his data that will not work
    with the new capabilities?

    2) when will the new version of NCL be released that contains this?

    Dear Dr. Murphy,

    Monty Peffley told me you might be able to help me. I have been working
    with Alex Warn-Varnas at NRL running ocean models and have recently
    began investigating the use of NCAR graphics to plot the results. I
    spent a fair amount of time going through the CONPACK documentation and
    found it reasonably easy to use for the examples given.

    My problem is our data is not rectangular. The data sets are
    temperature, salinity, etc versus depth generated periodically
    throughout a simulation. Typically we might use matlab or idl to contour
    the data for example 'contour, X,Y,D' where X,Y, and D are all MxN
    arrays, X contains the cartesian ranges at each grid point, Y the
    cartesian depths at each grid point, and D the data at each grid point.
    The ranges are evenly spaced (say 0, 100km in 50m intervals) but the
    depth array follows the bathymetry, so over a shelf the depth might vary
    from 0 to 100m in 10m increments but off the shelf the depth might vary
    from 0 to 500m in 50m increments. I thought that the NCAR example
    'ccpsps2' might work; it assumes addresses irregularly spaced data over
    a regular rectangle of X and Y values.

    If you head us in a direction which would solve our problem that would
    help us immensely. In any case, thanks for you time. Monte seems a
    little envious of you living in Boulder!
