E1455, Refactoring the Chart helper

What it does: 
1) This helper/chart class provides the templates of data. It also has pie diagrams and charts for the data.
2) Also contains fixes to display bar, line and pie charts. 

Can you give an example of a helper file which is included in views so that we can refer to that? 
Or should we rename this to chart_helper.rb as per your earlier comments.
