I need to implement gwt-highcharts draggable data points in java, similar to what's done in js here:
http://jsfiddle.net/highcharts/AyUbx/
I can't figure out how to do that in java from the gwt-highcharts javadocs. None of the mouse or click eventhandler documentation mentions how to capture drag info, or even how to capture mouse-up events, which combined with click events, would let detect a drag action. Any help or examples would be greatly appreciated. I'm using GWT 2.5.1, and the latest versions of gwt-highcharts and jquery as of 2014-01-03. Thanks in advance. -Dan Jones
