6 EZY - Draws, in a manner determined by the current values of the
7 control parameters, a complete graph of a single curve through the
8 points (I,YDRA(I)), for I from 1 to NPTS. The argument GLAB may be used
9 to specify a "graph label", to be placed at the top of the graph.
10
12 CALL EZY (YDRA,NPTS,GLAB)

15 #include <ncarg/ncargC.h>
16
17 void c_ezy (float *ydra, int npts, char *glab)
18
20 YDRA (an input array of type REAL, dimensioned at least NPTS)
21 defines the Y coordinates of points on the curve. The
22 current value of 'NULL/1.' (default value "1.E36") may be
23 used in YDRA to signal missing points; curve segments on
24 either side of a missing point are omitted.
25
26 NPTS (an input expression of type INTEGER) is the number of
27 curve points defined by the array YDRA.
28
29 GLAB (an input expression of type CHARACTER) defines a new
30 "graph label". (If the first character of this expression
31 is "CHAR(0)", no new "graph label" is defined; the current
32 one will continue to be used.) A character string defining
33 a new graph label must either be of the exact length
34 specified by the current value of 'LINE/MAXIMUM.' (default:
35 40 characters), or shorter; if shorter, it must be
36 terminated by the character defined by the current value of
37 'LINE/END.' (default: a '$'). The string becomes the new
38 text of line number 100 of the label named 'T'.
39
41 The C-binding argument descriptions are the same as the FORTRAN
42 argument descriptions.

45 Use the ncargex command to see the following relevant examples: agex01,
46 bnchmk, example, tagupw, tautog, fagezy.
47
49 To use EZY or c_ezy, load the NCAR Graphics libraries ncarg, ncarg_gks,
50 and ncarg_c, preferably in that order. To get smoother curves, drawn
51 using spline interpolation, also load libdashsmth.o. Or, you can use
52 the ncargf77 command to compile your program and load the above
53 libraries, then, to get smoother curves, use the -dashsmth option.
