PERIML - Draws a labeled perimeter with inward-pointing tick
marks. The directions and lengths of tick marks may be changed by calling
TICKS and/or TICK4.
CALL PERIML (MJRX,MNRX,MJRY,MNRY)
#include <ncarg/ncargC.h>
void c_periml (int mjrx, int mnrx, int mjry, int mnry)
- MJRX, MNRX, MJRY, and
MNRY
- (input expressions of type INTEGER) specify the major and minor divisions
of the horizontal (X) and vertical (Y) axes of the current viewport. The
meanings of these parameters depend on the current setting of the internal
parameter ´LS´ of SPPS:
- If the value of ´LS´ implies that the axis is linear:
MJRX(Y) specifies the number of major divisions of the X(Y) axis and
MNRX(Y) specifies the number of minor divisions within each major
division. In each case, the value specifies the number of spaces between
grid lines or ticks rather than the number of lines or ticks. Including
the ones at the ends of the axes, there is always one more major division
line or mark than the number of major divisions specified by MJRX(Y).
Similarly, there is always one less minor division line or tick per major
division than the number of minor divisions per major division specified
by MNRX(Y).
- If the value of ´LS´ implies that the axis is logarithmic:
Each major division point occurs at a value 10**MJRX(Y) times the previous
point. For example, if the minimum X-axis value were 3., the maximum
X-axis value 3000. and MJRX 1, then the major division points would be 3.,
30., 300., and 3000. If MNRX(Y).LE.10, there are nine minor divisions
within each major division. For example, between 3. and 30., there would
be minor division points at 6., 9., 12., . . . 27. If MNRX(Y).GT.10.,
minor divisions are omitted.
The C-binding argument descriptions are the same as the FORTRAN
argument descriptions.
The statement
CALL PERIML (MJRX,MNRX,MJRY,MNRY)
is equivalent to
CALL GRIDAL (MJRX,MNRX,MJRY,MNRY,1,1,5,0.,0.)
Use the ncargex command to see the following relevant example:
tgrida.
To use PERIML or c_periml, load the NCAR Graphics libraries ncarg,
ncarg_gks, and ncarg_c, preferably in that order.
