undefined method `renderChart'

[Eidher]

I'm doing this example: Creating a single series chart from data contained in arrays, but I got this error:

 

 

 

undefined method `renderChart'

 

 

 

I pasted the renderChart method in the application.rb.

 

 

 

What's wrong?

[srividya_sharma]

renderChart will usually be used from the view. Hence, this function should be copied to application_helper.rb from where it will be accessible to all the views.

It is recommended to use these functions as part of library modules instead of copying the function into your application_helper.
