[Paraview] Animation and XDMF

Hello everyone, 

I have generated a temporal grid where each dataset  and HDF file 
corresponds to a time step. When I hit the Play button in ParaView, It 
shows only the current dataset,  and the data from previous time steps 
disappears. Is it possible to accumulate all the data as the time 
progresses? Is there some sort of buffer? I would like to see how the 
final shape is being build up over time, but all I see is the data from 
the current time steps. 
For example, my shape is a line, and I plot it point by point, but I don't 
get the line, I just see one point at time from that line. 
what I would like to see is this 

time step 1     1st point, 
time step 2     1st and 2nd point, 
time step 3     1st, 2nd, and 3rd point 
and etc. 

I tried using Hyperslab and it worked for XML, but it completely did not 
work for HDF
I used this approach: "0 1 3 " for time =1, " 0 1 4" for time =2 and etc. 
But once I but HDF instead of XML as my second data item of the HyperSlab, 
it shows garbage values.

I also used and Function="Join($0; $1)" , but it did not work with neither 
XML nor HDF. 
I tried to join two HFD vectors into a larger one, to old and new points 
at time=2, but no success. 

I also tried selecting a part of HDF5 data, using Fucntion="($0[0:4]", but 
it crashes.


Does anybody have any insight, or a HyperSlab   examples? or examples with 
Functions that work with HDF? 
I
