Actionscript 3 轴上的Flex As3折线图分组

我想在设备上使用折线图组件显示这些类型的大规模数据， 我有一些过滤器，比如上周、上个月和过去3个月

都有一些/大量的数据

{ Date: "1/1/2015", Day:"Sunday" , DayAbv:"SUN", Severity: 2 }, 
{ Date: "1/2/2015", Day:"Monday" , DayAbv:"MON", Severity: 5},      
{ Date: "1/3/2015", Day:"Tuesday" , DayAbv:"TUE", Severity: 4},     
{ Date: "1/4/2015", Day:"Wednesday" , DayAbv:"WED", Severity: 7},   
{ Date: "1/5/2015", Day:"Thursday" , DayAbv:"THU", Severity: 5},
{ Date: "1/6/2015", Day:"Friday" , DayAbv:"FRI", Severity: 7},
{ Date: "1/7/2015", Day:"Saturday" , DayAbv:"SAT", Severity: 4}

与过去一个月和过去三个月的系列数据相同

如何根据下图对日期进行分组？ y轴上的值相同，但x轴上的日期应分组

在第二个折线图中，我有这些类型的数据

{ Time: "08:10",  Average: 1 , Date : "1/1/2015" , Appearance : "Yes" },
{ Time: "09:25",  Average: 1 , Date : "1/1/2015" , Appearance : "Yes" },
{ Time: "11:20",  Average: 0 , Date : "1/2/2015" , Appearance : "No" },
{ Time: "13:20",  Average: 0 , Date : "1/3/2015" , Appearance : "No" },
{ Time: "15:55",  Average: 1 , Date : "1/3/2015" , Appearance : "Yes" },
{ Time: "18:05",  Average: 0 , Date : "1/5/2015" , Appearance : "No" },
{ Time: "20:30",  Average: 1 , Date : "1/5/2015" , Appearance : "Yes" }

具体来说，我只想在X轴上显示Week1，在Week1中显示过去一周数据的所有上述点，以及过去一个月的Week1、week2、week3、week4等
单轴多点打印
