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

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

55 The statement
56 CALL GRID (MJRX,MNRX,MJRY,MNRY)
58 is equivalent to
60 CALL GRIDAL (MJRX,MNRX,MJRY,MNRY,0,0,0,0.,0.)

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

67 To use GRID or c_grid, load the NCAR Graphics libraries ncarg,
68 ncarg_gks, and ncarg_c, preferably in that order.
