// if you have a stacked area chart, the overrides you want to dispatch are as follows
chart. stacked.dispatch.on("areaClick", function(hadouken) { console.log(hadouken);}) // hadouken will give you the element you clicked on
chart.stacked.dispatch.on("areaClick.toggle", function(shinjuken) { });
// bar charts are similar
chart.multibar.dispatch.on("elementClick", function(e) { console.log(e)});
// you can even override legend clicks with these dudes
// of course returning null will just disable whatever you're working with.

// the only tricky bit is making sure your changes are preserved after an update on the chart itself (real time or window resize, etc)
