PHONOPY-PROPPLOT(1)

💖 PHONOPY-PROPPLOT 💖

okay bestie, welcome to phonopy-propplot, the little command-line cutie from the phonopy fam, version 2.48.0 — it lives in the User Commands section of the manual and it is here to plot your thermal properties. no cap. let's get into it 🦋

✨ NAME ✨

phonopy-propplot — manual page for phonopy-propplot 2.48.0

---

🌸 DESCRIPTION 🌸

so basically, here's how you call her:

usage: phonopy-propplot [-h] [--factor FACTOR] [--ymax YMAX] [--ymin
       YMIN]

       [--tmax TMAX] [--tmin TMIN] [--cv] [-s] [--fe]
              [-o OUTPUT_FILENAME] [-d] [--gnuplot] [filename ...]

phonopy-propplot command-line-tool 💅 that's the whole vibe. it plots your phonon thermal properties, and it ate.

🎀 positional arguments:

• filename — the filename of the phonon thermal properties result, which, iykyk, is thermal_properties.yaml. like, that's the file she's expecting, bestie 🍓

🧚 options:

• -h, --help — show this help message and exit. the classic "wait what does this do" button, we love her 😭
• --factor FACTOR — conversion factor of energy unit to internal electronic energy ✨ (yes queen, do the math for me)
• --ymax YMAX — maximum value of y axis 📈
• --ymin YMIN — minimum value of y axis 📉
• --tmax TMAX — maximum value of temperature 🔥 (how hot are we going)
• --tmin TMIN — minimum value of temperature 🧊 (how cold are we going)
• --cv, --heat_capacity — plot heat capacity 💜 these two flags are the same flag, bestie, just different outfits
• -s, --entropy — plot entropy 🌀
• --fe, --free_energy — plot free energy 🫶
• -o, --output OUTPUT_FILENAME — output filename 📝 (name your baby)
• -d, --diff — calculate difference ➖
• --gnuplot — damp thermal properties in gnuplot data style 🌈

---

lowkey reminder: that -o, --output line takes an argument called OUTPUT_FILENAME, exactly like it says up in the usage. don't @ me, just spell it right 💀

okay that's the whole thing!! go plot something iconic, bestie 👑

this was phonopy-propplot version 2.48.0, straight outta February 2026 — periodt 💖💅
