将大量数据汇总到有用的表格报告中的最佳方法是什么。
例如：
+---------------------+---------------------+-------------------+
| acctstarttime | acctstoptime | calledstationid |
+---------------------+---------------------+-------------------+

我们有数千行，并且正在尝试创建一个表（然后是图表），首先按星期几汇总数据。基本上，我们会尝试按天/小时显示使用情况。例如，2011年1月1日至2011年1月31日之间：
Monday 11
Tuesday 14
Wednesday 16
Thursday 12
Friday 09
Saturday 77
Sunday 08
是否有任何插件可以执行此操作，还是需要以其他方式进行汇总？
