Hello Paulo,

You can examine our online examples here.
The Numerical Axis example demonstrates how you can use DateTime for the X axis.

If you are new to our controls I suggest that you explore our online examples and help so that you get familiar with the chart's features, possibilities, limitations and how-to's.
