按小时AmCharts堆叠数据

Question

是否可以每小时堆叠数据？我只有两列：来自触发器的时间和信号＆＃34; trig = 1＆＃34;。所以我需要每小时堆叠所有触发信号。所以在Y轴上应该是每小时所有触发信号的数量和。您可以使用此示例JSFiddle。 数据如下所示：

$(".OffersContainer > div:gt(0)").hide();

$(".OffersContainer > span").click(function() {
    $(this).siblings($(this).hasClass('click') ? "div:gt(0)" : "div:lt(3)").slideDown();
    $(this).addClass('click');
});

我的JS：

[{"time":"15:15:00","trig":"1"},{"time":"15:45:00","trig":"1"},
{"time":"16:10:18","trig":"1"},{"time":"16:20:00","trig":"1"},
{"time":"17:30:00","trig":"1"},{"time":"17:50:00","trig":"1"},
{"time":"18:25:00","trig":"1"},{"time":"18:45:00","trig":"1"},
{"time":"19:05:00","trig":"1"},{"time":"19:40:00","trig":"1"},
{"time":"21:15:00","trig":"1"},{"time":"21:50:00","trig":"1"}]
