NAME

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.

SYNOPSIS

11       CALL CPCHHL (IFLG)
12

DESCRIPTION

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
19                   ·   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
23                   ·   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
27                   ·   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
31                   ·   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
35                   ·   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
39                   ·   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
43                   ·   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
47                   ·   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.

USAGE

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.
64

ACCESS

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