Hi,
I've found a problem with IE11. When multiple charts was rendered, IE11 throw some "out of stack space" errors.

This is the JSFiddle with my code.

After some tests I think the problem is in "highcharts-ng" plugin in this function (row 103):

`
this.$doCheck = function () {
if (!detector(ctrl.config, prevConfig)) {
prevConfig = angular.merge({}, ctrl.config);
mergedConfig = getMergedOptions($element, ctrl.config, seriesId);

		//Remove any unlinked objects before adding
		this.removeUnlinkedObjects(mergedConfig);

		//Allows dynamic adding Axes
		this.addAnyNewAxes(mergedConfig.yAxis, ctrl.chart, false);
		this.addAnyNewAxes(mergedConfig.xAxis, ctrl.chart, true);

		//Allows dynamic adding of series
		if (mergedConfig.series) {
			// Add any new series
			angular.forEach(ctrl.config.series, function (s) {
				if (!ctrl.chart.get(s.id)) {
					ctrl.chart.addSeries(s);
				}
			});
		}

		ctrl.chart.update(mergedConfig, true);
	}
};

`

To avoid the problem i've modified the function adding

if (ctrl.disableChangeDetection === true) { return; }

after the first row.

Is possible to fix the problem avoiding my workaround?
