GR_PLOT_CONST(1)

💫 GR_PLOT_CONST — the constellation plot bestie 💫

okay so this is gr_plot_const, straight out of the User Commands section of your manual, and it's about to make your I&Q data look stunning. 🦋

---

✨ NAME ✨

gr_plot_const — constellation plot of I&Q data using GNU Radio

---

🌸 SYNOPSIS 🌸

gr_plot_const: [options] input_filename

---

🎀 DESCRIPTION 🎀

So here's the vibe: this thing takes a GNU Radio complex binary file and shows you the I&Q data versus time and the constellation plot (that's I vs. Q, for the girlies keeping score). Two plots, one file, no cap. ✨

You can set the block size to control how many points get read in at a time, and you can set the start position in the file if you don't wanna start from the top like a coward. 💅

Now listen, this part matters: by default the system assumes a sample rate of 1, which means in the time plot, each sample just gets plotted versus the sample number. It's giving "index, not time." If you want a true time axis — like, actual time, main character energy — set the sample rate (-R or --sample-rate) to whatever sample rate was used when the samples were captured. That's it, that's the trick. 🫶

💖 OPTIONS 💖

• -h, --help — shows this help message and dips. exit. bye. 👋
• -B BLOCK, --block=BLOCK — specify the block size. it's [default=1000], so 1000 points at a time unless you say otherwise.
• -s START, --start=START — specify where to start in the file. [default=0], aka the very beginning, bestie.
• -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE — set the sampler rate of the data. yes it says "sampler rate" in the original and we're keeping it exactly like that, [default=1.0]. 🌈

also quick note: that's literally every option. four of them. short and sweet, unlike your FFTs. 😭
