There is a nice gem called 

<a href="https://github.com/topfunky/gruff" rel="nofollow noreferrer">gruff</a> 

for graphs in ruby. You'll need the fabulous <a href="http://www.imagemagick.org/" rel="nofollow noreferrer">imagemagick</a> and <a href="http://rmagick.rubyforge.org/" rel="nofollow noreferrer">rmagick</a> library. Since installation of the latter two is not really trivial (but not difficult, either), there's a <a href="http://rmagick.rubyforge.org/install-faq.html" rel="nofollow noreferrer">installation FAQ</a> for that. 

Looks something like this:

I need to display some charts/graphs based upon user inputs on my web aplication built using Ruby on Rails. Are there any charting libraries out there that I could use with ROR for displaying simple bar, line and pie graphs?

Ruby charting library?

我需要在使用Ruby on Rails构建的web应用程序上显示一些基于用户输入的图表/图形。有没有什么图表库可以和ROR一起用来显示简单的条形图、折线图和饼图？
