7 Conrec_family internal parameters.

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 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 For normal or smooth options the parameter set is:
25 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 For the quick option the parameter set is:
33 COMMON /CONRE1/ IOFFP ,SPVAL
35 COMMON /CONRE4/ ISIZEM ,ISIZEP ,NLA ,NLM ,
36 1 XLT ,YBT ,SIDE ,ISOLID ,
37 2 EXT ,IOFFD ,IOFFM
38 For the super option the parameter set is:
40 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 Definitions of the inclusive set follow:
47 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 ISIZEM Size of labels for minimums and maximums, as per
56 the size definitions given for ISIZEL.
57 [Default = 2]
58 ISIZEP Size of labels for data point values as per the
61 size definitions given for ISIZEL. [Default = 0]
62 NLA Approximate number of contour levels when
65 internally generated. [Default = 16]
66 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 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 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 SIDE Length of longer edge of plot (see also EXT).
84 [Default = .90]
85 NREP Number of repetitions of the dash pattern between
88 line labels. [Default = 6]
89 NCRT Number of CRT units per element (bit) in the dash
92 pattern. [Default = 4]
93 ILAB Flag to control the drawing of line labels.
96 - ILAB non-zero means label the lines.
98 - ILAB = 0 means do not label the lines.
100 [Default = 1]
102 NULBUL Number of unlabeled lines between labeled lines.
105 For example, when NULBLL = 3, every fourth level
106 is labeled. [Default = 3]
107 IOFFD Flag to control normalization of label numbers.
110 - IOFFD = 0 means include decimal point when
112 possible (do not normalize unless required).
113 - IOFFD non-zero means normalize all label
115 numbers and output a scale factor in the
116 message below the graph. [Default = 0]
117 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 IOFFP Flag to control special value feature.
127 - IOFFP = 0 means the special value feature is
129 not in use.
130 - 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 [Default = 0]
137 SPVAL Contains the special value when IOFFP is non-zero.
140 [Default = 0.]
141 IOFFM Flag to control the message below the plot.
144 - IOFFM = 0 if the message is to be plotted.
146 - IOFFM non-zero if the message is to be omitted.
148 [Default = 0]
150 ISOLID Dash pattern for non-negative contour lines.
153 [Default = 1023]
