EZMXY(3NCARG)

💖 EZMXY 💖 — from the NCAR GRAPHICS manual, bestie edition

okay so. hi. you're here because you wanna draw a whole entire graph. multiple curves, even. and you want it to be cute and easy. that's literally what EZMXY does — it's giving main character energy in the 3NCARG section of the manual, and it's here to serve. 🫶

✨ NAME ✨

EZMXY draws, in a manner determined by the current values of the control parameters, a complete graph of one or more curves, each defined by a set of points (XDRA(I),YDRA(I,J)) (or (XDRA(I),YDRA(J,I)) or (XDRA(I,J),YDRA(I,J)) or (XDRA(J,I),YDRA(J,I)), depending on the current value of 'ROW.'), for I from 1 to NPTS. The curve number J runs from 1 to MANY. The argument GLAB may be used to specify a "graph label", to be placed at the top of the graph.

like. it draws the whole graph. every curve. all of it. no cap. 💅

🦋 DESCRIPTION 🦋

• XDRA — an input array of type REAL, dimensioned NPTS or IDXY x MANY or IDXY x NPTS, depending on the current value of 'ROW.'. It holds your curve-point X coordinates. The current value of 'NULL/1.' (default value "1.E36") may be used in XDRA to signal missing points; curve segments on either side of a missing point are not drawn. Note: 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".
  • If 'ROW.' has the absolute value "1." (the default), XDRA is singly-dimensioned. It is subscripted by point number.
  • If 'ROW.' has the absolute value "2." or greater, XDRA is doubly-dimensioned. It is subscripted by point number and curve number, in that order if 'ROW.' is positive (the default), and in the reverse order if 'ROW.' is negative.
• YDRA — an input array of type REAL, dimensioned IDXY x MANY or IDXY x NPTS, depending on the current value of 'ROW.'. It holds your curve-point Y coordinates. The current value of 'NULL/1.' (default value "1.E36") may be used in YDRA to signal missing points; curve segments on either side of a missing point are not drawn. Note: 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".
  • If 'ROW.' is positive (the default), YDRA is subscripted by point number and curve number, in that order.
  • If 'ROW.' is negative, YDRA is subscripted by curve number and point number, in that order.
• IDXY — an input expression of type INTEGER, and it's the first dimension of the arrays XDRA (if it's doubly-dimensioned) and YDRA (unconditionally, bestie, no exceptions), which EZMXY needs in order to index these arrays properly. get it right or the vibes are off. 😭
  • If 'ROW.' is positive (the default), IDXY must be greater than or equal to NPTS.
  • If 'ROW.' is negative, IDXY must be greater than or equal to MANY.
• MANY — an input expression of type INTEGER. It's the number of curves to be drawn by EZMXY. how many little lines are we serving today. 👑
• NPTS — an input expression of type INTEGER. It's the number of points defining each curve to be drawn by EZMXY.
• GLAB — an input expression of type CHARACTER. It 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 'LINE/END.' (default: a '$'). The string becomes the new text of line number 100 of the label named 'T'.

lowkey important: that CHAR(0) thing? if you lead with it, nothing changes and the old label keeps vibing. and don't forget your '$' terminator if your string is short. ✨

💜 C-BINDING DESCRIPTION 💜

The C-binding argument descriptions are the same as the FORTRAN argument descriptions. literally identical. same facts, different language, we love consistency. 🎀

🌸 EXAMPLES 🌸

Use the ncargex command to see the following relevant examples: agex04, agex05, agex07, agex08, tagupw, tautog, fagaxclr, fagaxlbl, fagaxmax, fagcuclr, fagcudsh, fagezmxy, fagilclr, fagovrvw.

go look at them fr fr, they ate. 🔥

⭐ ACCESS ⭐

To use EZMXY or c_ezmxy, 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, you can use the ncargf77 command to compile your program and load the above libraries, then, to get smoother curves, use the -dashsmth option.

smoother curves = prettier graph = the moment. 🌈

okay that's the whole page, you're all caught up bestie 💅 this was EZMXY(3NCARG) from the UNIX manual, dated March 1993 — yes she's vintage, yes she still slays, periodt. 🎀🦋💖
