Example 016: Graph showing date time handling

1//! This examples shows Date/Time handling vith the Graph Object.
2//! The Graph is suited to show discontinuous date/time scales.
3//! Discontinuous for example, 8am to 5pm, Monday to Friday.
4 
5//! Here's a tip, when debugging your data-passing logic, use the
6//! built-in text export feature to verify that data is as
7//! expected.
