PLMESHC(3plplot)

💅 PLMESHC(3plplot) — the PLplot API, bestie edition 🎀

okay so you're in the PLplot manual, section 3plplot, and today's main character is plmeshc. buckle up bestie, this one's a glow-up of a classic ✨

✨ NAME ✨

plmeshc — magnitude colored plot surface mesh with contour. yes that's the whole name, it's giving "I do three things at once and I do them well" 💅

---

🌸 SYNOPSIS 🌸

plmeshc(x, y, z, nx, ny, opt, clevel, nlevel)

---

🦋 DESCRIPTION 🦋

So plmeshc is literally the more powerful form of plmesh(3plplot), no cap. It leveled up in three iconic ways:

• the surface mesh can be colored accordingly to the current z value being plotted 🔥
• a contour plot can be drawn at the base XY plane ✨
• a curtain can be drawn between the plotted function border and the base XY plane 🎀

Redacted form: plmeshc(x, y, z, opt, clevel)

This function is used in example 11. iykyk 👑

🧚 ARGUMENTS 🧚

• x (PLFLT_VECTOR(3plplot), input) — a vector containing the x coordinates at which the function is evaluated. that's it, that's the vibe 💖
• y (PLFLT_VECTOR(3plplot), input) — a vector containing the y coordinates at which the function is evaluated. matching energy, love that for us 🌸
• z (PLFLT_MATRIX(3plplot), input) — a matrix containing function values to plot. should have dimensions of nx by ny. so like, the actual data, the moment, the reason we're all here ⭐
• nx (PLINT(3plplot), input) — number of x values at which function is evaluated 🦋
• ny (PLINT(3plplot), input) — number of y values at which function is evaluated 🌈
• opt (PLINT(3plplot), input) — determines the way in which the surface is represented. here's the trick bestie: to specify more than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR. now let's break down the whole menu 💅
  • opt=DRAW_LINEX : lines are drawn showing z as a function of x for each value of y[j] .
  • opt=DRAW_LINEY : lines are drawn showing z as a function of y for each value of x[i] .
  • opt=DRAW_LINEXY : network of lines is drawn connecting points at which function is defined.
  • opt=MAG_COLOR : each line in the mesh is colored according to the z value being plotted. the color is used from the current cmap1.
  • opt=BASE_CONT : a contour plot is drawn at the base XY plane using parameters nlevel and clevel.
  • opt=DRAW_SIDES : draws a curtain between the base XY plane and the borders of the plotted function.
• clevel (PLFLT_VECTOR(3plplot), input) — a vector containing the contour levels. these are the contour vibes 🎀
• nlevel (PLINT(3plplot), input) — number of elements in the clevel vector 🍓

fr fr do not skip an option name or smash two together — they're additive, not merged. DRAW_LINEXY + MAG_COLOR is the blueprint, periodt 💀
