at work, I had to generate some simple charts that something should look better then Goolgle chart.
so I found nice library called Funsion chart free. it’s free to use for any purpose.
It has simple library for ruby on rails. but it wasn’t comfortable and it’s not even gem.
so I have created a gem for this.
first you need to put this in your gemfile
then you also need to do some command work.
rails g easyfsf
so you can use new helper method
here are some examples
<%= render_sm_chart("a", "Pie2D", ['a','b','c'], [1,2,3]) %>
