Chandresh,
From the chart it looks like provided data is not in order.. Please verify
1. That the x(date) values is in order
2. Month values being passed to the Date constructor follow zero based index – in javascript month values range from 0-11 (instead of 1-12). See this post
In case there is no issue as mentioned above, please provide the jsonObj values. That is the best way to figure out the problem.
