確保您的網頁呼叫jsapi和google.load()一次。 Qouted以下細節從Google Developer's Site

You may be using the Google Loader incorrectly.

Only load jsapi once. No matter how many charts you have on your web page, you should have one and only one call like this:

<script type="text/javascript" src="https://www.google.com/jsapi"></script> // Do this ONCE.

Ideally, call google.load only once, with all the packages you'll need for your web page.

執行多個包的負載像下面，

<script> 
     google.load("visualization", "1", {packages: ["corechart", "timeline"]}); 
</script>
