Network graph nodes connected line click event
For Network graph , when two nodes connected by one line, I want to click the line and trigger click event, and get the information of those two nodes
Thanks for sharing the idea! Here you can find simple plugin that adds events from `point.events` to links too: http://jsfiddle.net/BlackLabel/b8369zvh/
Note: You can distinguish nodes and links by simple checking `this.isNode` flag.
Links are actually points, but hover/tooltip is disabled so default events aren't fired (such link can no be assigned to `chart.hoverPoint` internally).
