Given an input that changes over time, vtkTemporalStatistics looks at the data for each time step and computes some statistical information of how a point or cell variable changes over time. For example, vtkTemporalStatistics can compute the average value of "pressure" over time of each point.
Note that this filter will require the upstream filter to be run on every time step that it reports that it can compute. This may be a time consuming operation.
vtkTemporalStatistics ignores the temporal spacing. Each timestep will be weighted the same regardless of how long of an interval it is to the next timestep. Thus, the average statistic may be quite different from an integration of the variable if the time spacing varies.

To create an instance of class vtkTemporalStatistics, simply invoke its constructor as follows
obj = vtkTemporalStatistics
obj
is an instance of the vtkTemporalStatistics class.
