NAME

       CONRAQ - draws a two dimensional contour map from irregularly distributed data.  This is
       the small quick version of the Conran_family.  It also has the fewest available number of
       options.

STATUS

       CONRAQ is approaching obsolescence.  If you have available an interpolation package which
       can do a random to gridded interpolation equal to that built into the Conran_family, then
       we recommend that you grid your dataset and use the Conpack utility instead.  Refer to the
       conpack and conpack_family_params man pages as well as the NCAR Graphics Contouring and
       Mapping Tutorial.

SYNOPSIS

       CONRAQ (XD,YD,ZD,NDP,WK,IWK)

DESCRIPTION

       XD          Input, real array -- of dimension NDP containing the X coordinates of the data
                   points.

       YD          Input, real array -- of dimension NDP containing the Y coordinates of the data
                   points.

       ZD          Input, real array -- of dimension NDP containing the data values at the
                   points.

       NDP         Input, integer -- is the number of data points to be contoured.  NDP must be 4
                   or larger.

       WK          Input, real array -- workspace of dimension 15*NDP.

       IWK         Input, integer array -- workspace which must be dimensioned at least
                   IWK((27+NCP)*NDP).

                   The parameter NCP controls the number of data points to be used in the
                   interpolation.  Increasing NCP causes more of the surrounding data to
                   influence the point of interpolation.  In the case of linear interpolation NCP
                   is always 4.  In the case of C1 interpolation, NCP can vary from 2 to 25 with
                   4 as the default.

                   The interpolation option is selected using parameter ITP.  See the
                   conran_family_params man page for a description of all internal parameters.

USAGE

       Contour lines are not smoothed or thinned, but a number of options are available through
       the use of internal parameters.  See the conran_family_params man page.

       Super and standard-and-smooth versions of the Conran_family are also available through
       entries CONRAS and CONRAN, respectively.

EXAMPLES

       Use the ncargex command to see the relevant example tconaq.

ACCESS

       To use CONRAQ, load the NCAR Graphics libraries conraq, ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.

       The special conraq library is not loaded as part of the normal NCAR Graphics installation.
       It can be loaded by the user directly, along with the above three standard libraries, or
       loaded implicitly through the use of the -quick option of the ncargf77 command.

       QUICK     Command: "ncargf77 -quick mycode.f"

MESSAGES

       See the conran_family man page for a description of all Conran_family error messages
       and/or informational messages.
