'Overview' icon -- Shortcut to top of page. Overview

CNiAxis3D encapsulates the interface to a single axis of a 3D graph control, which allows you to modify its appearance and behavior.

Individual axes are obtained via the Axes property on a CNiGraph3D object.

Note: To specify a date/time value, you must convert your date or time value to a double. A date is implemented as a floating-point value with the integer part of the number measuring days from midnight, 30 December 1899, and the fractional part representing the time of day. The absolute value of the fractional part of the number represents the time as a fraction of a day. Thus, 1 second equals 1 / 24 hours / 60 minutes, which is 1/86400 or approximately 1.157407e-5. So, midnight, 31 December 1899, is represented by 1.0. Similarly, 6 AM, 1 January 1900, is represented by 2.25, and midnight, 29 December 1899, is -1.0. However, 6 AM, 29 December 1899, is -1.25.
