Hi Below is the code i am using. The issue I have is ,the :data_label, accepts only methods which are fields in the database. I have another method in the model of @series called suppose "abc" so data_label => 'abc' will result in an javascript error and graph wont be rendered. For that matter even data_label => 'class' wont work! The error i get in the java script is
Uncaught Error: Invalid row index 1. Should be in the range [0-0].
