Yeah! I had given the same for the function, but it does not catch the syntax error !

First you need to find out whether syntax errors actually throw an exception or return a status variable. Check the documentation to see which.

Sorry i am new to this. But how can I display a message if the chart is not loaded ?

Sorry, no idea. As I suggested above you need to study Google's documentation for the API in question.
