测试执行？我使用的包含。
感谢您的帮助，我真正欣赏它。
然而，有些东西是不正确的。当我运行我的航班号是不能够进入listhistogrammer后的检查，只有县SHAPEFILE。......
我使用FME 2014 IDK的，如果这就是为什么它不是显示出来。我试图做你在你的第一篇文章解释什么，但它只是给了我个县有一个航班号载。如果全县有多个航班号码包含这将是空。
这是你送的样子，我的工作空间。

Ok, so I aggregated my point dataset (flight numbers) from over a million to just 26 multi point features.
I am now confused.
My end goal is to have a data set that lists each county name with the various flight numbers contained in that county.
I imagine this is going to be some sort of spatialfilter -- or point on area overlayer-- i just cant seem to get the parameters correct.
any thoughts?
Is there a way to make the flight numbers not repeat?i.e."Flight 1" Only appears once in the cell.
Are you actually interested in keeping the point geometry in any way, or is it sufficient to have the unique flight numbers for each county on the county geometry?
If the latter then a SpatialRelator (Counties as Requestor) followed by a ListHistogrammer (on _relationships{}.flightnumber will give you a list of all the flight numbers that fall inside the county (and how many times for each flight number).
What I want to know is all the different flight numbers that fall within each county.If I aggreage based on flight number and county name I only get the unique combinations.
My county data is in a different shapefile not associated with the point data.Will that matter?
The analysis I am doing is what different flight numbers fall within each county.
If you do a PointOnAreaOverlayer of the points with the counties you can get the county name (assuming you have that in an attribute) as an attribute of the points, then aggregate them on flight number and county name, that way you'll get an aggregate for all unique combinations of those two attributes and if you accumulate hulls they'll be smaller areas.
