6 CPCHHL - Called by Conpack routines as high/low labels are being drawn.
7 The default version does nothing. A user-written version may be
8 supplied to provide control as the labels are drawn.

11 CALL CPCHHL (IFLG)
12
14 IFLG (INTEGER, input) is positive if an action is about to be
15 taken, negative if an action has just been completed. The
16 action in question is defined by the absolute value of
17 IFLG, as follows:
18 · The value 1 implies the determination of the size of
20 the label for a high (by means of a call to PLCHHQ, in
21 the package Plotchar, with ANGD = 360.).
22 · The value 2 implies the filling of the box around the
24 label for a high, which is done before the drawing of
25 the label itself.
26 · The value 3 implies the drawing of the label for a high
28 (by means of a call to PLCHHQ, in the package
29 Plotchar).
30 · The value 4 implies the drawing of the box around the
32 label for a high, which is done after the drawing of
33 the label itself.
34 · The value 5 implies the determination of the size of
36 the label for a low (by means of a call to PLCHHQ, in
37 the package Plotchar, with ANGD = 360.).
38 · The value 6 implies the filling of the box around the
40 label for a low, which is done before the drawing of
41 the label itself.
42 · The value 7 implies the drawing of the label for a low
44 (by means of a call to PLCHHQ, in the package
45 Plotchar).
46 · The value 8 implies the drawing of the box around the
48 label for a low, which is done after the drawing of the
49 label itself.

52 The routine CPCHHL is not to be called by the user. It is called
53 several times by CPLBAM and/or CPLBDR while each high or low label is
54 positioned and drawn. The default version of CPCHHL does nothing. A
55 user-supplied replacement may change attributes such as color and line
56 width (by calling the SPPS routine SETUSV or the appropriate GKS
57 routines). The text of the label may be retrieved by means of a "CALL
58 CPGETC ('CTM',CVAL)". The text of the label may be changed by means of
59 a "CALL CPSETC ('CTM',CVAL)"; this should only be done during a call
60 with IFLG = 1, 3, 5, or 7; if it is done for one of the two values 5
61 and 7, it should also be done for the other. When CPCHHL is called,
62 the parameter 'ZDV' will have been set to the value of the high or low
63 being labelled; its value may be retrieved and used by CPCHHL.

66 To use CPCHHL, load the NCAR Graphics libraries ncarg, ncarg_gks, and
67 ncarg_c, preferably in that order.
