Using David’s example and a very helpful conversation with Sean I was able to
successfully use a Python track in animation and show the actual simulation
time.
I’m not an experienced Python user (as you’ll see in the example below), but I
got some simple code to work. Below is an example of the code I ended up with
in the Python animation track.
def start_cue: pass
def tick(self):
# set up the mapping from time step to date/time information
#
dateTimes = []
dateTimes.append( '4/1/2013 15:00' )
dateTimes.append( '4/1/2013 15:01' )
dateTimes.append( '4/1/2013 15:02' )
dateTimes.append( '4/1/2013 15:03' )
maxIndex = len(dateTimes)
index = int( self.GetClockTime() )
if index >= maxIndex :
index = maxIndex - 1
textSource = paraview.simple.FindSource("TheText")
textSource.Text = dateTimes[index]
def end_cue(self): pass
Thanks!

step
I think that Sean is on the right track and suggest that a Python Animation cue
is the way to go.
Attached is a state file to demonstrate. Load the state file in ParaView, open
Views->Animation View and double click on the existing Python track to see the
script that gets the pipeline time and feeds it into a text source for display.
I've left the parts about reading the file and mapping the Animation time into
the corresponding simulation time as an exercise to the reader.
Note: many time varying file formats produce the data time for you so this
translation is unnecessary and the Annotate Time filter will do what you want
it to.

Hi Sean,
Can we talk? I’m not smart enough to understand your suggestion (hate it when
that happens).
If I get something worked out, even a hack, I’ll post the solution back to this
list.
Thanks!

Hey Phil,
You *might* be able to hack it with a combination of a Programmable Filter and
a Python Annotation Filter. Use the Programmable Filter to add a FieldData
value to each time step that is a string with the appropriate date. Then use
the Python Annotation Filter to display the date as an annotation.
The first part is the hard one. The Programmable Filter could either (1) read
the file once to get all the dates, or (2) compute the dates using the starting
date, the time step value, and Python's datetime module.
Thanks,
Sean

Phil,
I have no idea how to put out what you are asking for, but it is a really good
idea. If you don’t get an answer, be sure to write up a bug report/ feature
request.

Subject: [EXTERNAL] [Paraview] displaying simulation time rather than time step
I would like to do something similar to the Annotate Time filter, but rather
than displaying the time step number, I need to display simulation date and
time.
I have a text file with the actual simulation date and time associated with
each time step. Here are the first few lines of that file
Time step Time step output, Actual time
0 0.00, 4/1/2013 15:00
1 65.83, 4/1/2013 15:01
2 125.88, 4/1/2013 15:02
3 201.00, 4/1/2013 15:03
4 268.65, 4/1/2013 15:04
5 328.83, 4/1/2013 15:05
6 366.46, 4/1/2013 15:06
…
So, rather than Time: 0 at the bottom of the 3D window, I’d like to have
4/1/2013 15:00
Any thoughts / recommendations on how to accomplish this task will be greatly
appreciated.
Thanks,
Phil
