Time Parameters
Parameters are normally supplied from selected columns of the parent data table, or from action controls:
Time parameters values can also be supplied through using the Time Window filter and selecting one of the three available time parameters.
q $Snapshot
q $TimeWindowStart
q $TimeWindowEnd
When one of the time window filters is moved, an action associated with one of these time parameters will be executed.
A final time parameter can also be specified. This is the FocusTime.
FocusTime is set when executing an action from a time series visualization and highlighting a particular time slice.
