Answer 1

Google图表具有最大长度的URL，无需提供错误即可处理。我不确定这个限制是什么，但是你的URL长度是4774个字符，我认为限制只是超过2000个字符。

您可能需要使用简单或扩展数据编码而不是文本编码。文本编码是为Google Charts API编码数据的空间效率最低的方法。有关详细信息，请参阅Data Formats API文档。

Answer 2

正如格雷格所说，你的网址太长了。

网址的最大长度不是由Google Chart API决定的，而是由网络浏览器和网络服务器考虑决定的。目前，不推荐在URL编码时（例如，|变为％7C）长度超过2048个字符的URL。随着Web浏览器和服务器的发展，这个数字可能会发生变化。有关更深入的讨论，请参阅http://www.boutell.com/newfaq/misc/urllength.html。

虽然这已经得到了正确回答，但我认为使用您的数据提供实用的解决方案可能很有用：

<form id='graphform' name='graphform' action='https://chart.googleapis.com/chart' method='POST' target='graph_target'>
  <input type="hidden" name="cht" value='lxy' />
