TimeDifferenceTComputeDataSourceValue Class

Returns a series of values that represent the time difference, in time units, between consecutive values in the source series. The units parameter, optional, specifies the type of time units and must be one of the following: Seconds, Nanoseconds, Microseconds, Milliseconds, Minutes, Hours, Days, Weeks, Ke (i.e., traditional Chinese unit of decimal time), Ticks (i.e., 100-nanosecond intervals), PlanckTime or AtomicUnitsOfTime - defaults to Seconds.

Properties
 NameDescription
Public propertyAliases Gets any defined aliases for the Grafana function.
(Inherited from TimeDifferenceT)
Public propertyAllowedGroupOperations Gets set of group operations that the Grafana function allows.
(Inherited from TimeDifferenceT)
Public propertyCategory Gets the category of the Grafana function, i.e., built-in or custom.
(Inherited from GrafanaFunctionBaseT)
Public propertyDataTypeIndex Gets the data source value type index associated with the Grafana function.
(Inherited from GrafanaFunctionBaseT)
Public propertyDescription Gets the description of the Grafana function.
(Inherited from TimeDifferenceT)
Public propertyInternalParameterCount Gets the number of internal parameters of the Grafana function.
(Inherited from GrafanaFunctionBaseT)
Public propertyIsSliceSeriesEquivalent Gets or sets a flag indicating whether the function behaves equivalently when processed as a series or as a slice. Value defaults to true for functions that return a series of values, i.e., the return type is Series, and the AllowedGroupOperations includes the flag for Slice operations; otherwise, value defaults to false when the return type is a scalar value, i.e., Scalar, or the AllowedGroupOperations does not include the flag for Slice operations.
(Inherited from GrafanaFunctionBaseT)
Public propertyName Gets the name of the Grafana function.
(Inherited from TimeDifferenceT)
Public propertyOptionalParameterCount Gets the number of optional parameters of the Grafana function.
(Inherited from GrafanaFunctionBaseT)
Public propertyParameterDefinitions Gets the list of defined parameter definitions for the Grafana function.
(Inherited from TimeDifferenceT)
Public propertyPublishedGroupOperations Gets set of group operations that the Grafana function exposes publicly.
(Inherited from TimeDifferenceT)
Public propertyRequiredParameterCount Gets the number of required parameters, not including data source values expression, of the Grafana function.
(Inherited from GrafanaFunctionBaseT)
Public propertyResultIsSetTargetSeries Gets flag that determines if function result is target series for set-based group operations.
(Inherited from GrafanaFunctionBaseT)
Public propertyReturnType Gets the return type of the Grafana function, i.e., scalar or series.
(Inherited from TimeDifferenceT)
