DESCRIPTION

10       No parameter setting functions are available for the Conrec_family
11       utility.  Parameters were set through common blocks CONRE1 and CONRE4.
12       There are three versions of the CONREC code.  The normal version is in
13       the standard NCAR Graphics library.  The other two versions are in
14       optional libraries one of which is linked when the ncargf77 option
15       -quick, or -super is declared on the command line.
16
17       The CONREC and EZCNTR entries can be invoked in four different ways to
18       create contour plots which vary considerably in appearance.  The four
19       variations include quick, normal, smooth, and super contour lines.
20       This progression represents a tradeoff between speed of computation and
21       the appearance of the contour plots.  These variations are specified
22       through selected command line options of the ncargf77 command.
23
24       For normal or smooth options the parameter set is:
25
26        COMMON /CONRE1/ IOFFP      ,SPVAL
27        COMMON /CONRE4/ ISIZEL     ,ISIZEM     ,ISIZEP     ,NREP       ,
28       1                NCRT       ,ILAB       ,NULBLL     ,IOFFD      ,
29       2                EXT        ,IOFFM      ,ISOLID     ,NLA        ,
30       3                NLM        ,XLT        ,YBT        ,SIDE
31
32       For the quick option the parameter set is:
33
34        COMMON /CONRE1/ IOFFP      ,SPVAL
35        COMMON /CONRE4/ ISIZEM     ,ISIZEP     ,NLA        ,NLM        ,
36       1                XLT        ,YBT        ,SIDE       ,ISOLID     ,
37       2                EXT        ,IOFFD      ,IOFFM
38
39       For the super option the parameter set is:
40
41        COMMON /CONRE1/ IOFFP      ,SPVAL      ,IHILO
42        DATA ISIZEL,ISIZEM,ISIZEP,NLA,NLM,XLT,YBT,SIDE,ISOLID,NREP,NCRT/
43       1       1,  2,   0, 16, 40,.05,.05,  .9,  1023,   6,   4/
44        DATA EXT,IOFFD,NULBLL,IOFFM,ILAB/.25,0,3,0,1/
45
46       Definitions of the inclusive set follow:
47
48
49
50       ISIZEL      Size of line labels in Plotter Address Units (PAUs).
51                   0 = 8 PAUs,  1 = 12 PAUs, 2 = 16 PAUs, 3 = 24 PAUs,
52                   > 3 means use this number of PAUs.  [Default = 1]
53
54
55       ISIZEM      Size of labels for minimums and maximums, as per
56                   the size definitions given for ISIZEL.
57                   [Default = 2]
58
59
60       ISIZEP      Size of labels for data point values as per the
61                   size definitions given for ISIZEL.  [Default = 0]
62
63
64       NLA         Approximate number of contour levels when
65                   internally generated.  [Default = 16]
66
67
68       NLM         Maximum number of contour levels.  If this is to be
69                   increased, the dimensions of CL and RWORK in conrec.f
70                   must be increased by the same amount.  [Default = 40]
71
72
73       XLT         Left hand edge of the plot (0.0 is the left edge of
74                   the frame and 1.0 is the right edge of the frame.)
75                   [Default = .05]
76
77
78       YBT         Bottom edge of the plot (0.0 is the bottom of the
79                   frame and 1.0 is the top of the frame.)
80                   [Default = .05]
81
82
83       SIDE        Length of longer edge of plot (see also EXT).
84                   [Default = .90]
85
86
87       NREP        Number of repetitions of the dash pattern between
88                   line labels.  [Default = 6]
89
90
91       NCRT        Number of CRT units per element (bit) in the dash
92                   pattern.  [Default = 4]
93
94
95       ILAB        Flag to control the drawing of line labels.
96
97                   - ILAB non-zero means label the lines.
98
99                   - ILAB = 0 means do not label the lines.
100
101                   [Default = 1]
102
103
104       NULBUL      Number of unlabeled lines between labeled lines.
105                   For example, when NULBLL = 3, every fourth level
106                   is labeled.  [Default = 3]
107
108
109       IOFFD       Flag to control normalization of label numbers.
110
111                   - IOFFD = 0 means include decimal point when
112                     possible (do not normalize unless required).
113
114                   - IOFFD non-zero means normalize all label
115                     numbers and output a scale factor in the
116                     message below the graph.  [Default = 0]
117
118
119       EXT         Lengths of the sides of the plot are proportional
120                   to M and N (when CONREC sets the window and viewport).
121                   In extreme cases, when MIN(M,N)/MAX(M,N) is less
122                   than EXT, Conrec produces a square plot.
123                   [Default = .25]
124
125
126       IOFFP       Flag to control special value feature.
127
128                   - IOFFP = 0 means the special value feature is
129                     not in use.
130
131                   - IOFFP non-zero means the special value feature
132                     is in use.  (SPVAL is set to the special value.)
133                     Contour lines will then be omitted from any cell
134                     with any corner equal to the special value.
135
136                   [Default = 0]
137
138
139       SPVAL       Contains the special value when IOFFP is non-zero.
140                   [Default = 0.]
141
142
143       IOFFM       Flag to control the message below the plot.
144
145                   - IOFFM = 0  if the message is to be plotted.
146
147                   - IOFFM non-zero if the message is to be omitted.
148
149                   [Default = 0]
150
151
152       ISOLID      Dash pattern for non-negative contour lines.
