NAME

       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.

SYNOPSIS

       CALL PERIML (MJRX,MNRX,MJRY,MNRY)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_periml (int mjrx, int mnrx, int mjry, int mnry)

DESCRIPTION

       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.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       The statement

          CALL PERIML (MJRX,MNRX,MJRY,MNRY)

       is equivalent to

          CALL GRIDAL (MJRX,MNRX,MJRY,MNRY,1,1,5,0.,0.)

EXAMPLES

       Use the ncargex command to see the following relevant example: tgrida.

ACCESS

       To use PERIML or c_periml, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
