NAME¶
AGUTOL - Provides a way for the user to change the user-system-to-label-system
mapping for one or more of the four axes.
SYNOPSIS¶
SUBROUTINE AGUTOL (IAXS,FUNS,IDMA,VINP,VOTP)
DESCRIPTION¶
- IAXS
- (an input expression of type INTEGER) is the number of the axis. The
values 1, 2, 3, and 4 imply the left, right, bottom, and top axes,
respectively.
- FUNS
- (an input expression of type REAL) is the value of 'AXIS/s/FUNCTION.',
which may be used to select the desired mapping function for the axis
IAXS. It is recommended that the default value (zero) be used to specify
the identity mapping. The value may be integral ("1.",
"2.", etc.) and serve purely to select the code to be executed
or it may be the value of an actual parameter in the equations defining
the mapping.
- IDMA
- (an input expression of type INTEGER) specifies the direction of the
mapping. A value greater than zero indicates that VINP is a value in the
user system and that VOTP is to be a value in the label system, a value
less than zero the opposite. The mappings in one direction must be the
mathematical inverses of the mappings in the other direction.
- VINP
- (an input expression of type REAL) is an input value in one coordinate
system.
- VOTP
- (an output variable of type REAL) is an output value in the other
coordinate system.
USAGE¶
This routine is not called by the user program, but by Autograph itself. It
defines the user-system-to-label-system mapping for all four axes. The default
version makes the label system match the user system on all four axes. The
user may supply his own version of this routine to change the mapping on one
or more of the axes. Mappings defined by the subroutine must be continuous and
monotonic.
Note: A user version of AGUTOL should not call any other Autograph routine.
ACCESS¶
To use AGUTOL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
preferably in that order.
