Hi Ramya,
Since you mentioned about "clickable charts", I assume you are writing a web application.
You can implement double click functionality in a web page using standard HTML/Javascript. The double click event in HTML/Javascript is called ondblclick. You may refer to HTML/Javascript for more details on this event. There is an example in ChartDirector called "Javascript Clickable Charts" that demonstrates how to attach HTML/Javascript event handlers to hot spots. May be you can use it as a reference.
Hope this can help.
