Disabling zoom about eventdrops

[maherbeg]

Ah, figured it out. May be worth enabling as a config option.

  d3.select($('rect.zoom')[0]).call(zoom);

Thank you @maherbeg I had the same situation -- note, that it's unclear exactly what your solution was from the snippet you posted (I assume you created a custom zoom behavior and that's how you override?)

Folks who simply want to disable zoom try:

d3.select($('rect.zoom')[0]).on('.zoom', null);

@slifty I actually ended up not using that. I cheated and proxied addEventListener to enable toggling of the zooming function.

var proxiedAdd = Element.prototype.addEventListener;
  var enableZoom$ = $('#zoom-element');
  Element.prototype.addEventListener = function(type, listener, useCapture) {

    var listenerToAdd = listener;
    if (type === 'wheel') {
      listenerToAdd = function() {
        if (enableZoom$.is(':checked')) {
          listener.apply(this, arguments);
        }
      };
    }
    proxiedAdd.call(this, type, listenerToAdd, useCapture);
  };

Indeed, it should be configurable. We are currently working on the next version. Let's add it the new configuration file. :)
