例如:http://jsfiddle.net/highcharts/72gA7/7/

片段:

// Generic code to add zoom cancelling by hitting escape
Highcharts.Pointer.prototype.cancelDrag = function () {
    if (this.selectionMarker) {
        this.selectionMarker = this.selectionMarker.destroy();
    }
    this.drop();
};
$(document).keyup(function (e) {
    if (e.charCode == 27) { // esc
        $.each(Highcharts.charts, function () {
            this.pointer.cancelDrag();
        });
    } // esc
});
