| Icon | Type | Description |
|---|---|---|
 | Count |
Gets the number of intervals in this DateTimeScale.
|
| IsOrdered |

In C#, this property is the indexer for the DateTimeScale class. |
Remarks
There are two ways to supply the intervals. The first is to supply an array containing the boundaries of the intervals. Every value except the first and the last acts both as the upper bound of one interval and the lower bound of the next. The second way is to supply an interval and a DateTimeUnit value that specify the width or length in time of each interval. Time units can be hours, days, weeks, months, or years. In this case, the interval is divided into subintervals, each covering the specified length of time. This method takes into account that the number of days varies from month to month.
DateTimeScale inherits from CategoricalScale. The intervals of the DateTimeScale correspond to the levels of the CategoricalScale.
The Map(Object) method maps a DateTime value to an interval. Overloads are available that map many values in one operatioin
Using a DateTimeScale, a DateTimeVariable can be transformed into a CategoricalVariable.
