6 CPDRPL - Provides a useful polyline-drawer for the routine CPCLDM.
7
9 CALL CPDRPL (XCS, YCS, NCS, IAI, IAG, NAI)
10
12 XCS (a REAL array of dimension at least NCS, input) is an array
13 containing the X coordinates of NCS points defining a
14 polyline.
15
16 YCS (a REAL array of dimension at least NCS, input) is an array
17 containing the Y coordinates of NCS points defining a
18 polyline.
19
20 NCS (INTEGER, input) is the number of points defining the
21 polyline.
22
23 IAI (an INTEGER array of dimension at least NAI, input) is an
24 array of area identifiers for the area in which the
25 polyline lies. For each I from 1 to NAI, IAI(I) is the area
26 identifier of the area with respect to the edge group
27 IAG(I).
28
29 IAG (an INTEGER array of dimension at least NAI, input) is an
30 array of group identifiers. See the description of IAI,
31 above.
32
33 NAI (INTEGER, input) is the number of area identifiers in the
34 array IAI and the number of group identifiers in the array
35 IAG.
36
38 If CPCLDM is called, and the only object of using it, instead of
39 CPCLDR, to draw contour lines is to avoid drawing the lines through
40 labels, then, in the routine which calls CPCLDM, put the declaration
41
42 EXTERNAL CPDRPL
43
44 and, in the call to CPCLDM, use CPDRPL for the argument RTPL. Each time
45 CPDRPL is called, it draws the polyline defined by its first three
46 arguments if, and only if, none of the area identifiers defined by the
47 other three arguments is negative.
48
50 To use CPDRPL, load the NCAR Graphics libraries ncarg, ncarg_gks, and
51 ncarg_c, preferably in that order.
