   If the support for plotting has been removed (because its shifted to daru-view) we need to remove the appropriate notebooks from README and sciruby-notebooks.

   I don't think it is removed from the daru. It looks different issue. I am able to run these lines using latest code.

   @Shekharrajak Ok, but these lines are certainly not working in latest daru release.

   NoMethodError: undefined method `plot' for "#<Daru::Vector(3)>\n   0   1\n   1   2\n   2   3"
   	from /var/lib/gems/2.3.0/gems/daru-0.2.1/lib/daru/vector.rb:1420:in `method_missing'
   	from (irb):4
   	from /usr/bin/irb:11:in `<main>'

   @Shekharrajak Also I'm getting error (the same I mentioned on top) on latest code. You might want to test on a new computer with only latest daru installed because that's what I did.

   Yes! I already tried the latest cloned version :

    ➜  daru git:(master*) bundle console 
   irb(main):001:0> require 'daru'
   => false
   irb(main):002:0> Daru.plotting_library = :gruff
   => :gruff
   irb(main):003:0> dv = Daru::Vector.new [1, 2, 3]
   => #<Daru::Vector(3)>
      0   1
      1   2
      2   3
   irb(main):004:0> dv.plot do |p|
   irb(main):005:1*   p.title = 'lol'
   irb(main):006:1> end
   => #<Gruff::Bar:0x000055ae4fac16a8 @columns=500.0 .................
   
   

   I'll check 0.2.1

   @Shekharrajak You are right, #plot is working in latest code. I hadn't installed gruff, so it was giving this weird error.

   Thanks for the update. Actually, I tried in 0.2.1 version also it was fine.

   I think a new Daru release is needed as with the last release the sciruby-notebooks won't be working. Also could you verify if gnuplot working for you?

   Following lines give me Illegal seek error. What about you?

   require 'gnuplotrb'
   require 'daru'
   include GnuplotRB
   
   dv = Daru::Vector.new [:a, :a, :a, :b, :b], type: :category
   Plot.new [dv.frequencies, with: 'histogram'], xrange: -1..2, yrange: 0..10

   @lokeshh , I installed gnuplotrb gem and run sudo apt-get install gnuplot-x11. It worked for me.

    Hi,
    I'm having the same error, I'm using Daru-0.2.2. Is this something fixed in the master branch? And if so, are you planning to do a release at some point? I prefer to use a fixed release for consistency.
    Best,
    Ricardo.

    Hi @lokeshh and @v0dro,

    I'm using daru (0.3) and I'm getting the same error
    SystemStackError: stack level too deep
    Do you have the same issue on your end ?

    @NicolasNeiman You need to install gruff gem first. You can do that by running gem install gruff.

    @homonecloco I'm using daru 0.3 and plotting with gruff is working for me. I just had to add that gem using gem install gruff. If you see an error let me know.
