我正在尝试填充Google Charts中的地理图表。
基本上，我在SELECT avg(TValue)
from
(
-- this will give you only the values for the current part/ppf/dimension
select * from ProductProperty
where Partno = @Partno and PPFno = @PPFno and DName = @Dimension
) myrow
unpivot
(
TValue
for TCol in (T1, T2, ... T44, T45)
) as x
中进行人数统计。如果我仅执行STATE, ZIPCODE, COUNT和STATE，则效果很好。但是当我尝试添加邮政编码时，地图生成不正确。
那是我的代码：
COUNT我不明白为什么将邮政编码添加到数据中时，它只会返回一个空白地图。如果我将<html>

更改为resolution，则与'metros'相比，它似乎在地图上提供了更精细的级别。
在Google GeoCharts中这可能吗？
