6 DISPLA - Changes the values of certain primary control parameters
7 purportedly having to do with the "display" of a graph.

14 void c_displa(int lfra, int lrow, int ltyp)
16
18 LFRA (an input expression of type INTEGER), if non-zero, must
19 have an integer value, the real equivalent of which is to
20 become the new value of 'FRAME.'. If LFRA is zero, no
21 change is to be made in the current value of 'FRAME.'.
22 · The default value of 'FRAME.' is "1.", specifying
24 that each of the routines EZY, EZXY, EZMY, and EZMXY
25 is to do a frame advance after drawing a graph.
26 · The value "2." specifies no frame advance.
28 · The value "3." specifies a frame advance before
30 drawing a graph.
31 LROW (an input expression of type INTEGER), if non-zero, must
33 have an integer value, the real equivalent of which is to
34 become the new value of 'ROW.'. If LROW is zero, no change
35 is to be made in the current value of 'ROW.'. This
36 parameter affects the way in which the routines EZMY and
37 EZMXY interpret the arguments XDRA and YDRA, as follows:
38 · If 'ROW.' is positive, the first subscript of YDRA
40 is a point number and the second subscript is a
41 curve number. If 'ROW.' is negative, the order of
42 the subscripts is reversed (row-wise, rather than
43 column-wise, storage).
44 · If the absolute value of 'ROW.' is "1.", XDRA is
46 singly-subscripted; its subscript is a point number.
47 If the absolute value of 'ROW.' is "2." or greater,
48 XDRA is doubly-subscripted; the order of the
49 subscripts is the same as for YDRA.
50 The default value of 'ROW.' is "1.", specifying that XDRA
52 is singly-subscripted by point number and that YDRA is
53 doubly-subscripted by point number and curve number, in
54 that order.
55 LTYP (an input expression of type INTEGER), if non-zero, is an
57 integer specifying new values for 'X/LOGARITHMIC.' and
58 'Y/LOGARITHMIC.'. If LTYP is zero, no change is to be made
59 in the current values.
60 · The parameter 'X/LOGARITHMIC.' has the default value
62 "0.", specifying a linear mapping of user X
63 coordinates onto the horizontal axis of the grid
64 window; it may be given either of the two values
65 "-1." or "+1." to specify a logarithmic mapping. The
66 value "-1." protects it from being reset as a side
67 effect of setting 'SET.'. DISPLA generates the value
68 "0." or "-1.".
69 · The parameter 'Y/LOGARITHMIC.' is defined similarly
71 and affects the mapping of user Y coordinates onto
72 the vertical axis of the grid window.
73 A non-zero LTYP resets these values, as follows:
75 LTYP 'X/LOGARITHMIC.' 'Y/LOGARITHMIC.'

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

98 To use DISPLA or c_displa, load the NCAR Graphics libraries ncarg,
99 ncarg_gks, and ncarg_c, preferably in that order.
