NAME

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.

SYNOPSIS

12       CALL EZY (YDRA,NPTS,GLAB)
13

C-BINDING SYNOPSIS

15       #include <ncarg/ncargC.h>
16
17       void c_ezy (float *ydra, int npts, char *glab)

DESCRIPTION

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'.

C-BINDING DESCRIPTION

41       The C-binding argument descriptions are the same as the FORTRAN
42       argument descriptions.
43

EXAMPLES

45       Use the ncargex command to see the following relevant examples: agex01,
46       bnchmk, example, tagupw, tautog, fagezy.
47

ACCESS

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.
