[Paraview] Annotate Time with legacy vtk series

[Jason Hoogland]

Hi Ken,

Ok, I tried that.  I have a N=98 legacy vtk series and want to map the 0->97 time steps to 4575->7000.  So when TemporalShiftScale is applied, from trial and error it seems to m=n*a+m0 where n=1..N, a is the scale, m0 is the shift.  But in the Animation Inspector "Start" is still shown as 0 even though "End" is now 7000 (for any Play Mode) - first problem.  Even so, second problem (same as before) is that when an Annotate Time source text is added, with the Sequence Play Mode, again, moving the animation forward (pressing |> button) increments the time display (i.e. 777.77.., 1555.55..., ... 7000) but keeps the data view on the final data series.  Feels like a bug but maybe I have to set up keyframes.  Normally its all automatic.

No, that is the wrong way to go about it.  Changing the timekeeper time will
adjust the times sent to the reader.  You will still have the mismatch
ParaView will not load in all of the time steps that you want.

Instead, apply the "Temporal Shift Scale" filter to your data to adjust its
range to the desired values.  You will probably also have to change the
animation mode to Sequence to force ParaView to ignore the timesteps
reported from the original reader.
