Hello,

I am a beginner paraview user, and am running into what seems to be a basic issue, appreciate any pointers as to what I am doing wrong.  
I have a exodus file that contains information over multiple timesteps. In the GUI I can easily go to a particular timestep and see the range of values for a particular field viz. temperature. However, when I try to do this in pvpython, it looks like I always get the values for timestep 0.

You see temperature is 0 at timestep 0

At the final timestep, temp is non zero

 ![timestep-last](https://discourse.paraview.org/uploads/default/original/2X/0/08ef68fa26c7231638db7391c4e23aa198831976.png)

However, in pvpython I always get the range of temperature for timestep 0  
I used the following [pages](https://docs.paraview.org/en/v5.12.1/Tutorials/SelfDirectedTutorial/batchPythonScripting.html). However, I couldnt find an example of how to do time stepping there so I tried using the getanimationscene module to no avail. Is there a simple way to do this?

Appreciate the help! Let me know if something seems confusing/unclear.

Looks like a similar question was asked [here](https://discourse.paraview.org/t/get-the-range-of-last-timestep/13139).

However, the solution of UpdatePipeline suggested there didnt work.

`reader.UpdatePipeline(timesteps[n])` should do the trick

Ah! Thanks! I see the UpdatePipeline accepts time argument. Knew it had to be something trivial. It works now!
