NAME

6       CONRAQ - draws a two dimensional contour map from irregularly
7       distributed data.  This is the small quick version of the
8       Conran_family.  It also has the fewest available number of options.
9

STATUS

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

SYNOPSIS

19       CONRAQ (XD,YD,ZD,NDP,WK,IWK)
20

DESCRIPTION

22       XD          Input, real array -- of dimension NDP containing the X
23                   coordinates of the data points.
24
25       YD          Input, real array -- of dimension NDP containing the Y
26                   coordinates of the data points.
27
28       ZD          Input, real array -- of dimension NDP containing the data
29                   values at the points.
30
31       NDP         Input, integer -- is the number of data points to be
32                   contoured.  NDP must be 4 or larger.
33
34       WK          Input, real array -- workspace of dimension 15*NDP.
35
36       IWK         Input, integer array -- workspace which must be dimensioned
37                   at least IWK((27+NCP)*NDP).
38
39                   The parameter NCP controls the number of data points to be
40                   used in the interpolation.  Increasing NCP causes more of
41                   the surrounding data to influence the point of
42                   interpolation.  In the case of linear interpolation NCP is
43                   always 4.  In the case of C1 interpolation, NCP can vary
44                   from 2 to 25 with 4 as the default.
45
46                   The interpolation option is selected using parameter ITP.
47                   See the conran_family_params man page for a description of
48                   all internal parameters.
49

USAGE

51       Contour lines are not smoothed or thinned, but a number of options are
52       available through the use of internal parameters.  See the
53       conran_family_params man page.
54
55       Super and standard-and-smooth versions of the Conran_family are also
56       available through entries CONRAS and CONRAN, respectively.
57

EXAMPLES

59       Use the ncargex command to see the relevant example tconaq.

ACCESS

62       To use CONRAQ, load the NCAR Graphics libraries conraq, ncarg,
63       ncarg_gks, and ncarg_c, preferably in that order.
64
65       The special conraq library is not loaded as part of the normal NCAR
66       Graphics installation.  It can be loaded by the user directly, along
67       with the above three standard libraries, or loaded implicitly through
68       the use of the -quick option of the ncargf77 command.

72       QUICK     Command: "ncargf77 -quick mycode.f"

76       error messages and/or informational messages.
