NAME¶
CPCHHL - Called by Conpack routines as high/low labels are being drawn. The
default version does nothing. A user-written version may be supplied to
provide control as the labels are drawn.
SYNOPSIS¶
CALL CPCHHL (IFLG)
DESCRIPTION¶
- IFLG
- (INTEGER, input) is positive if an action is about to be taken, negative
if an action has just been completed. The action in question is defined by
the absolute value of IFLG, as follows:
- •
- The value 1 implies the determination of the size of the label for a high
(by means of a call to PLCHHQ, in the package Plotchar, with ANGD =
360.).
- •
- The value 2 implies the filling of the box around the label for a high,
which is done before the drawing of the label itself.
- •
- The value 3 implies the drawing of the label for a high (by means of a
call to PLCHHQ, in the package Plotchar).
- •
- The value 4 implies the drawing of the box around the label for a high,
which is done after the drawing of the label itself.
- •
- The value 5 implies the determination of the size of the label for a low
(by means of a call to PLCHHQ, in the package Plotchar, with ANGD =
360.).
- •
- The value 6 implies the filling of the box around the label for a low,
which is done before the drawing of the label itself.
- •
- The value 7 implies the drawing of the label for a low (by means of a call
to PLCHHQ, in the package Plotchar).
- •
- The value 8 implies the drawing of the box around the label for a low,
which is done after the drawing of the label itself.
USAGE¶
The routine CPCHHL is not to be called by the user. It is called several times
by CPLBAM and/or CPLBDR while each high or low label is positioned and drawn.
The default version of CPCHHL does nothing. A user-supplied replacement may
change attributes such as color and line width (by calling the SPPS routine
SETUSV or the appropriate GKS routines). The text of the label may be
retrieved by means of a "CALL CPGETC ('CTM',CVAL)". The text of the
label may be changed by means of a "CALL CPSETC ('CTM',CVAL)"; this
should only be done during a call with IFLG = 1, 3, 5, or 7; if it is done for
one of the two values 5 and 7, it should also be done for the other. When
CPCHHL is called, the parameter 'ZDV' will have been set to the value of the
high or low being labelled; its value may be retrieved and used by CPCHHL.
ACCESS¶
To use CPCHHL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
preferably in that order.
