I am new to Ruby on Rails, AJax, and JQuery. I have a Rails 2.35 app that has a HighCharts line graph on a page. I want to pass the x, y values to a Rails model function. I know how to get the x, y value but I do not know how to use the JQuery/AJax post to the server to pass the x, y values and retrieve the processed information from the model function. Can someone point me to an example?
