EZXY(3NCARG)

✨ EZXY ✨ (the NCAR Graphics one, bestie 💅)

okay so literally this is EZXY from NCARG (that's the NCAR Graphics world, and this page lives in section 3NCARG, iykyk 🎀). What does it do? It draws — in a manner determined by the current values of the control parameters — a complete graph of a single curve through the points (XDRA(I),YDRA(I)), for I from 1 to NPTS. And the argument GLAB? That's your moment to specify a "graph label" to sit pretty at the top of the graph. 👑

🌸 SYNOPSIS 🌸

CALL EZXY (XDRA,YDRA,NPTS,GLAB)

🦋 C-BINDING SYNOPSIS 🦋

#include <ncarg/ncargC.h>

void c_ezxy (float *xdra, float *ydra, int npts, char *glab)

💖 DESCRIPTION 💖

• XDRA — an input array of type REAL, dimensioned NPTS, that defines the X coordinates of points on the curve. 🫶
• YDRA — an input array of type REAL, dimensioned NPTS, that defines the Y coordinates of points on the curve. 🫶

The points on the curve have coordinates (XDRA(I),YDRA(I)), for I from 1 to NPTS. The current value of 'NULL/1.' (default value "1.E36") may be used to signal missing data in these arrays. If either coordinate of a point is missing, the point is considered to be missing; curve segments on either side of a missing point are not drawn.

⚠️ Note, bestie: because all non-missing coordinates are used in figuring the minimum and maximum user values along a given axis, it is safest to mark both coordinates as "missing". fr fr, do both. 😭

• NPTS — an input expression of type INTEGER, and it's the number of curve points defined by the arrays XDRA and YDRA. 🔢
• GLAB — an input expression of type CHARACTER that defines a new "graph label". (If the first character of this expression is "CHAR(0)", no new "graph label" is defined; the current one will continue to be used. 💀) A character string defining a new graph label must either be of the exact length specified by the current value of 'LINE/MAXIMUM.' (default: 40 characters), or shorter; if shorter, it must be terminated by the character defined by the current value of text of line number 100 of the label named 'T'. ✨

🌈 C-BINDING DESCRIPTION 🌈

The C-binding argument descriptions are the same as the FORTRAN argument descriptions. no cap, they're identical 💜

🍓 EXAMPLES 🍓

Use the ncargex command to see the following relevant examples: agex02, agex06, agex09, agex10, agex11, agex12, splogy, sprevx, tagupw, tautog, fagezxy, fspponts. Go look at them, they ate. 🔥

👑 ACCESS 👑

To use EZXY or c_ezxy, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

To get smoother curves, drawn using spline interpolation, also load libdashsmth.o.

Or — plot twist — you can use the ncargf77 command to compile your program and load the above libraries, then, to get smoother curves, use the -dashsmth option. ✨
