Google Fusion API和显示所有数据的问题 [英] Google Fusion API and issues with displaying all the data
问题描述
我想做的是在科罗拉多州展示葡萄园.它显示自定义图标，它们位于正确的位置；但是，它不会显示所有数据.超过50个时，仅显示11个点.反正还有吗?
What I am trying to do is display vineyards in Colorado. It displays the custom icons and they are in the correct places; however, it does not display all the data. Only 11 points are being showed when there is over 50 of them. Is there anyway around this?
编辑:这也是我的Google Fusion表.也许我的格式是错误的? https://www.google.com/fusiontables/DataSource?docid = 1pYFq7mJ1uT4YYZ3LLzY4l7X8njLmZszJt05lucY#rows:id = 1
Here is also my Google Fusion table. Perhaps my formatting is wrong? https://www.google.com/fusiontables/DataSource?docid=1pYFq7mJ1uT4YYZ3LLzY4l7X8njLmZszJt05lucY#rows:id=1
将Fusion地图与此进行比较: http://s5.postimg.org/f80q3qhpz/display .png
Compare the Fusion map to this: http://s5.postimg.org/f80q3qhpz/display.png
这是我的HTML和Javascript.

推荐答案
您正在对地址进行地理编码，这将导致OVER_QUERY_LIMIT错误(大约10个左右):
You are geocoding the addresses, that will run into OVER_QUERY_LIMIT errors (at about 10 or so):
添加其他类似内容以查看它们:
Add an else like this to see them:
if (status == google.maps.GeocoderStatus.OK) {
// .. your code
} else {
alert("geocode failed:"+status);
}
您在表格中有经度和纬度，可使用它们显示标记，而无需使用地理编码器.
You have the latitude and longitude in the table, use them to display the marker, don't use the geocoder.
