DateTime feature allows the display of date and/or time values to be formatted on any x or y-axis. The DateTime data format is implemented as a floating-point value (double), measuring days from midnight, December 30, 1899. So, midnight, December 31, 1899 is represented by 1.0. Similarly, 6 AM, January 1, 1900 is represented by 2.25.
XY Chart Net uses Microsoft's set of user-defined date/time format characters. A complete list of Custom DateTime Format Strings can be found in Microsoft's MSDN library, NET Framework Developer's Guide.
