图表对象格式错误

Question

我无法弄清楚如何正确格式化日期（Xaxis），否则，下面的代码可行。 MyArY()包含日期，但由于某种原因，日期显示在图表9/1/00上的00年？我已经尝试过我在网上找到的例子，但它们对我不起作用 以下是工作表上的日期： 7/21/15 8:00:00 AM 8/25/15 9/1/15 12:00:00 AM 9/10/15 7/21/15 8/25/15 图表无法识别日期，它们看起来像这样：

感谢您的帮助。

'将日期转换为值/双倍然后转换为整数以截断时间 MyArX（iVal）= Int（CDbl（aCell.Offset（0,2）.Value））

这对我有用。
