18 MJRX, MNRX, MJRY, and MNRY
19 (input expressions of type INTEGER) specify the major and
20 minor divisions of the horizontal (X) and vertical (Y) axes
21 of the current viewport. The meanings of these parameters
22 depend on the current setting of the internal parameter
23 ´LS´ of SPPS:
24
25 · If the value of ´LS´ implies that the axis is
26 linear: MJRX(Y) specifies the number of major
27 divisions of the X(Y) axis and MNRX(Y) specifies the
28 number of minor divisions within each major
29 division. In each case, the value specifies the
30 number of spaces between grid lines or ticks rather
31 than the number of lines or ticks. Including the
32 ones at the ends of the axes, there is always one
33 more major division line or mark than the number of
34 major divisions specified by MJRX(Y). Similarly,
35 there is always one less minor division line or tick
36 per major division than the number of minor
37 divisions per major division specified by MNRX(Y).
38
39 · If the value of ´LS´ implies that the axis is
40 logarithmic: Each major division point occurs at a
41 value 10**MJRX(Y) times the previous point. For
42 example, if the minimum X-axis value were 3., the
43 maximum X-axis value 3000. and MJRX 1, then the
44 major division points would be 3., 30., 300., and
45 3000. If MNRX(Y).LE.10, there are nine minor
46 divisions within each major division. For example,
47 between 3. and 30., there would be minor division
48 points at 6., 9., 12., . . . 27. If MNRX(Y).GT.10.,
49 minor divisions are omitted.

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

56 The statement
57
58 CALL GRIDL (MJRX,MNRX,MJRY,MNRY)
59
60 is equivalent to
61
62 CALL GRIDAL (MJRX,MNRX,MJRY,MNRY,1,1,0,0.,0.)

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

68 To use GRIDL or c_gridl, load the NCAR Graphics libraries ncarg,
69 ncarg_gks, and ncarg_c, preferably in that order.
