Can anyone please let me know which is the best software in ubuntu to plot graph against data??

If you like to make perfect graphs (and don't mind spending some time on them) I'd recommend using matplotlib (a python library) which has good mix of depth and simplicity. Otherwise, just use LibreOffice's Calc for quick graphing.

  • @karel I think John is talking about the learning curve that takes some time. – don.joey Jan 4 '14 at 8:57
  • @user1693801 Hi. On Ask Ubuntu you don't need to say thanks. You can just upvote (the little up arrow on the left of the question). That will give John some reputation. – don.joey Jan 4 '14 at 9:25
  • @don.joey Hi,i appreciate your concern, but i just created my account,and to vote up i need to have have some reputation. I'm lacking that as of now. – Ganesh Jan 4 '14 at 9:28
  • @Ganesh ah Ganesh. I completely forgot about that. Sorry. By accepting the question you also give him some rep so that is good. – don.joey Jan 4 '14 at 9:35

A program which in my opinion is far superior to Calc or matplot lib, is Veusz. It has a simple graphical interface, and can produce beautiful plots (allmost all graphs I publish now come from veusz as you can export as PDF and SVG vectored images allow scaling without pixelation, combined with the great quality).

I was using Octave for a while. Is a perfect alternative for Matlab.

  • +1 for octave, but I'm not sure "perfect" is how I'd describe it. – virtualxtc Jan 22 '14 at 22:32

I always use desmos.com. It's an "online graphing calculator".
