PLSCMAP0N(3plplot)

✨ PLSCMAP0N ✨

okay so bestie, welcome to the PLplot API glow-up of PLSCMAP0N — yes the whole page is in caps, it's giving very main character, we love that for it. 💅

---

🌸 NAME 🌸

plscmap0n — set the number of colors in cmap0, like a vibe check but for your palette 🎨

---

🦋 SYNOPSIS 🦋

plscmap0n(ncol0)

---

💖 DESCRIPTION 💖

So plscmap0n sets how many colors live in cmap0 (peep the PLplot documentation for the full tea ☕). It allocates — or reallocates, no cap — cmap0, and then fills in default values for any of those colors that weren't already allocated before. Basically it's restocking the shelves, but make it color. 🍓

The first 16 default colors are listed in the plcol0(3plplot) documentation, iykyk. For any index bigger than that, the default color is red. That's it. That's the color. 🚩

⚠️ heads up bestie: the drivers are not guaranteed to support more than 16 colors. So like, you can ask for more, but the driver might just not show up to the party. 💀

Redacted form: plscmap0n(ncol0) — yes they literally call it the "redacted form," we're not gonna question it, it's iconic. 🎀

This function is used in examples 15, 16, and 24. Slay, honestly. 👑

---

🌈 ARGUMENTS 🌈

• ncol0 ( PLINT(3plplot), input ) — the number of colors that will be allocated in the cmap0 palette. 🌸 And here's the little plot twist: if this number is zero or less, then the value from the previous call to plscmap0n(3plplot) gets used instead — and if there's no previous call, then a default value steps in. So 0 is basically "girl, use whatever we had before." 🙈
