PLSTRANSFORM(3plplot)

💫 PLSTRANSFORM 💫

okay so bestie, we're looking at plstransform(3plplot) from the PLplot API and honestly? it's giving glow-up for your whole plot window ✨

---

✨ NAME ✨

plstransform — sets a global coordinate transform function, no cap 🫶

---

🎀 SYNOPSIS 🎀

plstransform(coordinate_transform, coordinate_transform_data)

---

🦋 DESCRIPTION 🦋

so the way this works: you use this function to define a coordinate transformation that affects all elements drawn within the current plot window — like, every single one, it's lowkey main character energy 👑

the coordinate_transform callback function is similar to the one you'd hand to the plmap(3plplot) and plmeridians(3plplot) functions, iykyk 💅

and the coordinate_transform_data parameter? that's your little side-channel — you can use it to pass extra data to coordinate_transform 🎁

Redacted form: General: plstransform(coordinate_transform, coordinate_transform_data)

this function is used in examples 19 and 22 (go look at them fr fr, they ate) 🔥

---

🌈 ARGUMENTS 🌈

• coordinate_transform (PLTRANSFORM_callback(3plplot), input) — a callback function that defines the transformation from the input (x, y) world coordinates to new PLplot world coordinates. If coordinate_transform is not supplied (e.g., is set to NULL in the C case), then no transform is applied — so like, chill mode, nothing happens 🙈
• coordinate_transform_data (PLPointer(3plplot), input) — optional extra data for coordinate_transform. optional! no pressure bestie 💜
