Graph / chart library for Ruby?


I am working with Ruby since several months and I’m very impressed of
this language.
Over the weekend I explored the Rails framework and now I’m thinking
about to rebuild some of my PHP web applications with Ruby/Rails.

I found a Ruby port for the FPDF library what made me very happy, now
I’m search for a good library to create graphs / charts.
In PHP I used JPGraph, is there something comparable in Ruby available?


Check out Gruff. Very young, but also very promising. Pretty too.


You can try koolchart or Google free chart charting library.
