CONOP3(3NCARG) | NCAR GRAPHICS | CONOP3(3NCARG) |
CONOP3 - sets option switches and specifys various REAL parameters to be used by the Conran_family utility.
CALL CONOP3 (IOPT, ARRAY, LENA)
'CHL=ON' or 'CHL=OFF' 'CIL=ON' or 'CIL=OFF' 'CON=ON' or 'CON=OFF' 'DBP=ON' or 'DBP=OFF' 'SDC=ON' or 'SDC=OFF' 'SLD=ON' or 'SLD=OFF' 'TEN=ON' or 'TEN=OFF'
If an option is turned 'ON', then the remaining CONOP3 arguments can be used to override the default settings of that option.
If the option is 'OFF', then the remaining arguments of the CONOP3 call can be any dummy values. Option settings will be returned to their default values.
The following options are defined by this subroutine:
If program set: CALL CONOP3('CHL=OFF',0.,0)
If user set: CALL CONOP3('CHL=ON',ARRAY,2) where ARRAY(1)=HI, ARRAY(2)=FLO
Note: The values supplied for contour increment and contour high and low values assume unscaled data values. See the SDC parameter, below.
If program set: CALL CONOP3('CIL=OFF',0.,0)
If user set: CALL CONOP3('CIL=ON',CINC,1)
Note: By default, ('CIL=OFF') the program will examine the user's input data and determine the contour interval (CINC) at some appropriate range between the level of high and low values supplied, usually generating between 15 and 20 contour levels.
Example: CALL CONOP3('CIL=ON',10.,1)
will generate contours at increments of 10. units in user coordinates.
If program set: CALL CONOP3('CON=OFF',0.,0)
If user set: CALL CONOP3('CON=ON',ARRAY,NCL)
Note: The real array (ARRAY) must have the contour levels ordered from smallest to largest.
Warning: It is illegal to use the CON option when either CIL or CHL are activated. If this is done, the option call that detected the error will not be executed.
If program set: CALL CONOP3('DBP=OFF',0.,0)
If user set: CALL CONOP3('DBP=ON',BP,1)
Note: BP is a floating point number where the break for GTR and LSS contour dash patterns are defined. BP is assumed to be given relative to the untransformed contours.
To see how various dash line patterns can be assigned to various contours see parameter DBP in "man conop4".
If program set: CALL CONOP3('SDC=OFF',0.,0)
If user set: CALL CONOP3('SDC=ON',ARRAY,1)
Note: The data plotted on contour lines and the data plotted for relative minimums and maximums will be scaled by ARRAY.
To input a shield:
CALL CONOP3('SLD=ON',ARRAY,LENA)
Otherwise:
CALL CONOP3('SLD=OFF',0.,0)
Note: ARRAY is a real array LENA elements long. The first LENA/2 elements are X coordinates and the second LENA/2 elements are Y coordinates. This polygon must be closed, that is the first and last points in ARRAY must be the same.
Example:
DIMENSION SHLD(10)
DATA SHLD/ 7.,10.,10.,7.,7., 1 7.,7.,10.,10.,7./
CALL CONOP3 ('SLD=ON',SHLD,10)
If program set: CALL CONOP3('TEN=OFF',0.,0)
If user set: CALL CONOP3('TEN=ON',TENS,1)
Note: This option is not available in the standard version of CONRAN.
CONOP3 is called to set parameters of type REAL before CONRAN, CONRAQ, or CONRAS are called to generate the contour plot.
Use the command ncargex to see the following examples: tconaq, tconan, and tconas.
To use CONOP3 load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
See the conran_family man page for a description of all Conran_family error messages and/or informational messages.
