Add onmousemove event handler

[masayuki0812]

This should be able to work as:

• Called when mouse moving in the chart
• Accept the position of mouse as a argument

Are you looking for something like this?

data: {
  columns: [...],
  onclick: function (d, element) { console.log("onclick", d, element); },
  onmouseover: function (d) { console.log("onmouseover", d); },
  onmouseout: function (d) { console.log("onmouseout", d); }
}

Yes, it would be data.onmousemove and just onmousemove.

Is it possible to have those events called on the graph area? I would like to be able to select a portion on the graph (i.e. a "bounding box") with the mouse and have a callback that gets x1,x2,y1,y2 of the selected rectangle.
Any hints?

Thanks!

Piggybacking on this issue, it seems unclear how to get the element that the callback function is called in response for. I'd propose that either the event object or the element (or both) get passed as argument functions; i.e.,

oninit: function(e, el) { ... }

Does this make sense?

When this will be implemented?
