Routines
result = cgCoord::INIT( [POSITION=float] [, /XLOG] [, XRANGE=various] [, /YLOG] [, YRANGE=various] [, _REF_EXTRA=various])The initialization method of the object.
cgCoord::Draw, _EXTRA=_EXTRAThis method sets up the data coordinate space of the object by drawing an "invisible" plot.
cgCoord::GetProperty, POSITION=POSITION, XLOG=XLOG, XRANGE=XRANGE, YLOG=YLOG, YRANGE=YRANGE, _REF_EXTRA=_REF_EXTRAThis method allows the user to get various properties of the object.
cgCoord::SetProperty, POSITION=POSITION, XLOG=XLOG, XRANGE=XRANGE, YLOG=YLOG, YRANGE=YRANGE, _EXTRA=_EXTRAThis method allows the user to set various properties of the object.
cgCoord::CLEANUPThis is the clean-up routine for the object.
cgCoord__Define [, class]This is the class definition module.
Routine details
top cgCoord::INIT
result = cgCoord::INIT( [POSITION=float] [, /XLOG] [, XRANGE=various] [, /YLOG] [, YRANGE=various] [, _REF_EXTRA=various])
The initialization method of the object.
Keywords
- POSITION in optional type=float
The normalized position of the map projection space in the graphics window. The default position is [0.075, 0.075, 0.925, 0.900].
- XLOG in optional type=boolean default=0
Set this keyword if you wish the X axis range to be logarithmic.
- XRANGE in optional type=various
Set this keyword to the X axis range desired in the data coordinate system. The default os [0,1].
- YLOG in optional type=boolean default=0
Set this keyword if you wish the Y axis range to be logarithmic.
- YRANGE in optional type=various
Set this keyword to the Y axis range desired in the data coordinate system. The default os [0,1].
- _REF_EXTRA in optional type=various
Any keywords appropriate for superclass objects can also be specified.
top cgCoord::Draw
cgCoord::Draw, _EXTRA=_EXTRA
This method sets up the data coordinate space of the object by drawing an "invisible" plot.
Keywords
- _EXTRA
top cgCoord::GetProperty
cgCoord::GetProperty, POSITION=POSITION, XLOG=XLOG, XRANGE=XRANGE, YLOG=YLOG, YRANGE=YRANGE, _REF_EXTRA=_REF_EXTRA
This method allows the user to get various properties of the object. In general, the same keywords that are used for the INIT method can be used here.
Keywords
- POSITION
- XLOG
- XRANGE
- YLOG
- YRANGE
- _REF_EXTRA
top cgCoord::SetProperty
cgCoord::SetProperty, POSITION=POSITION, XLOG=XLOG, XRANGE=XRANGE, YLOG=YLOG, YRANGE=YRANGE, _EXTRA=_EXTRA
This method allows the user to set various properties of the object. In general, the same keywords that are used for the INIT method can be used here.
Keywords
- POSITION
- XLOG
- XRANGE
- YLOG
- YRANGE
- _EXTRA
