The impossible gnuplot graphs

This post is going to be a short one. I would only like to announce that most of the material presented here is collected in a more orderly fashion on my web page .



Comments should still be posted here.
Cheers!

  1. Hi!
    I started using gnuplot a couple of months ago and it is impressive the things that you can do with it!
    Can you make 3D polar graphs?
    Thanks,

  2. Hi Phinx,

    I don't quite know what you mean by a 3D polar graph. If you gave an example (a link to an graph that you have in mind), I would try my hand at it.

  3. Hi Gnuplotter,

    great blog! I'm currently trying to create some nice fancy histograms with gnuplot which should look like the ones from M$ Office. (I've to admit i really like their look *sighs*)

    It'd be really cool if you write me back at alexander.krause@erazor-zone.de

    Thanks a lot :-)

  6. @Phinx: check out http://t16web.lanl.gov/Kawano/gnuplot/parametric-e.html
    In short do "set parametric; r(t)=5; plot [t=0:2pi] r(t)*cos(t),r(t)*sin(t)" to draw a circle of radius 5

    ...and why the hell can't I paste into this text box :@

  7. Hi,

    What version of gnuplot supports these plots?

  8. Hi,

    Somehow gnuplot 4.4.2 is not recognizing 'png' termninal. And when I use your sample script for phonged histograms, it just pops up a white display which disappears in a moment. Any help on this?

  9. Hi Devesh,

    Everything here should work with gnuplot 4.4, and most of it should even work with version 4.2. I am afraid, I can't really comment on the problem that you mentioned above. I have never encountered anything like this.
    I am sorry I couldn't help more.
    Cheers,
    Zoltán
