DISPLA - Changes the values of certain primary control parameters
purportedly having to do with the "display" of a graph.
CALL DISPLA(LFRA,LROW,LTYP)
#include <ncarg/ncargC.h>
void c_displa(int lfra, int lrow, int ltyp)
- LFRA
- (an input expression of type INTEGER), if non-zero, must have an integer
value, the real equivalent of which is to become the new value of
'FRAME.'. If LFRA is zero, no change is to be made in the current value of
'FRAME.'.
- The default value of 'FRAME.' is "1.", specifying that each of
the routines EZY, EZXY, EZMY, and EZMXY is to do a frame advance after
drawing a graph.
- The value "2." specifies no frame advance.
- The value "3." specifies a frame advance before drawing a
graph.
- LROW
- (an input expression of type INTEGER), if non-zero, must have an integer
value, the real equivalent of which is to become the new value of 'ROW.'.
If LROW is zero, no change is to be made in the current value of 'ROW.'.
This parameter affects the way in which the routines EZMY and EZMXY
interpret the arguments XDRA and YDRA, as follows:
- If 'ROW.' is positive, the first subscript of YDRA is a point number and
the second subscript is a curve number. If 'ROW.' is negative, the order
of the subscripts is reversed (row-wise, rather than column-wise,
storage).
- If the absolute value of 'ROW.' is "1.", XDRA is
singly-subscripted; its subscript is a point number. If the absolute value
of 'ROW.' is "2." or greater, XDRA is doubly-subscripted; the
order of the subscripts is the same as for YDRA.
-
- The default value of 'ROW.' is "1.", specifying that XDRA is
singly-subscripted by point number and that YDRA is doubly-subscripted by
point number and curve number, in that order.
- LTYP
- (an input expression of type INTEGER), if non-zero, is an integer
specifying new values for 'X/LOGARITHMIC.' and 'Y/LOGARITHMIC.'. If LTYP
is zero, no change is to be made in the current values.
- The parameter 'X/LOGARITHMIC.' has the default value "0.",
specifying a linear mapping of user X coordinates onto the horizontal axis
of the grid window; it may be given either of the two values
"-1." or "+1." to specify a logarithmic mapping. The
value "-1." protects it from being reset as a side effect of
setting 'SET.'. DISPLA generates the value "0." or
"-1.".
- The parameter 'Y/LOGARITHMIC.' is defined similarly and affects the
mapping of user Y coordinates onto the vertical axis of the grid
window.
-
- A non-zero LTYP resets these values, as follows:
| LTYP |
'X/LOGARITHMIC.' |
'Y/LOGARITHMIC.' |
| ---- |
---------------- |

The C-binding argument descriptions are the same as the FORTRAN
argument descriptions.
This routine sets internal parameter values. For a complete list
of parameters available in this utility, see the autograph_params man
page.
Use the ncargex command to see the following relevant example:
agex13. bnchmk, splogy, sprevx.
To use DISPLA or c_displa, load the NCAR Graphics libraries ncarg,
ncarg_gks, and ncarg_c, preferably in that order.
