Hi Prabakaran,
The only way of passing DateTime string values to your XAxis is by manually setting custom strings as a TickPoints Labels. You may find this demonstrated in our
help topic.
Alternatively if you want to use the XValue property which is of type double, you will have to convert your values to OLE Automation dates first: see
DateTime.ToOADate().
More about DateTime support can be found here:

Hope this helps.
