GSL-HISTOGRAM(1)

💖 GSL-HISTOGRAM 💖

okay so bestie, we're looking at the General Commands Manual page for gsl-histogram, and honestly? it's a little cutie. let's get into it 💅

✨ NAME ✨

gsl-histogram — it computes a histogram of data coming in on stdin. that's it. that's the whole job. queen behavior 👑

✨ SYNOPSYS ✨

gsl-histogram xmin xmax [n]

(no bestie, "SYNOPSYS" isn't my typo, that's literally what it says up top, we're keeping it, it's canon now 💀)

✨ DESCRIPTION ✨

so gsl-histogram is a demonstration program for the GNU Scientific Library. think of it as the library showing off its fit. 🫶

it takes three arguments:

1. the lower bound of the histogram (xmin)
2. the upper bound of the histogram (xmax)
3. the number of bins (n)

then it just... reads numbers from stdin, one line at a time, and adds them to the histogram. no drama, no fuss, she's just vibing and counting. 🌸

when there's no more data to read, it prints out the accumulated histogram using gsl_histogram_fprintf. iconique.

and here's the little detail you don't wanna miss: if n is unspecified, then bins of integer width are used. periodt. 💖

✨ EXAMPLE ✨

okay here's a whole example, walk with me 🚶‍♀️✨

we generate 10000 random samples from a Cauchy distribution with a width of 30, and we histogram them over the range -100 to 100, using 200 bins. slay.

gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat

a plot of the resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample size. like, the vibe is there, the little wobbles are just the sample size being a finite little guy. no cap. 📈

awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X

and that's a wrap on the page, bestie!! this came to you from GNU and it lives under the name GSL-HISTOGRAM(1) 💖✨🎀 go histogram something iconic today, ily 🫶🌈👑
