我想做的是展示科罗拉多州的葡萄园。它显示自定义图标,并且它们位于正确的位置;但是,它并没有显示所有的数据。当超过50分时,只显示出11分。这附近有什么吗?
编辑:这也是我的Google Fusion表。也许我的格式不对?https://www.google.com/fusiontables/DataSource?docid=1pYFq7mJ1uT4YYZ3LLzY4l7X8njLmZszJt05lucY#rows:id=1
将Fusion贴图与以下内容进行比较:http://s5.postimg.org/f80q3qhpz/display.png
这是我的HTML和Javascript。

您正在对地址进行地理编码,这将遇到OVER_QUERY_LMIT错误(大约10个):
添加其他类似的内容来查看它们:
if (status == google.maps.GeocoderStatus.OK) {
// .. your code
} else {
alert("geocode failed:"+status);
}
你在表中有纬度和经度,用它们来显示标记,不要使用地理编码。
使用FusionTableLayer 的数据
