Question

我需要帮助。我想在时间表图表中查看过去24小时。这是格式化的日期时间DD / MM / YYYY HH：MM：SS。

这是数据来源：https://docs.google.com/spreadsheets/d/1H602ZpDfwl044qjDyIDfscOWoaSqLzjsvb3TuZXEK6c/edit#gid=0

我收到错误：未捕获的SyntaxError：意外的令牌ILLEGAL

有没有人有任何想法解决这个问题？

google.setOnLoadCallback(drawChart);

function drawChart() {

这纯粹是一个JS问题。你在JS中有一个不属于的额外引用。设置时间时，应该是：

var dateString = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + second;

而不是

var dateString = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + second';

如果删除无关的引用，您的错误就会消失。
