The Discontinuous Axis Demo shows how to use a new Axis type – the DiscontinuousDateTimeAxis – which is a DateTime Value Axis (measures X-position by X-value) that allows collapsing of gaps in the data.

For example, a DiscontinuousDateTimeAxis and a dataset of trading data (futures, forex or stocks), the DiscontinuousDateTimeAxis can be used to show or hide weekend or overnight gaps in data.

A calendar is applied to the DiscontinuousDateTimeAxis which contains the times to skip. Special days such as holidays or weekends can also be skipped.

Finally, the DiscontinuousDateTimeAxis may be used in process control systems, which require a DateTimeAxis but removing of certain times or date ranges from the axis.
