[Paraview] Plotting line over time

[Alexander Grayver]

Hello ParaView team,

Discovering further ParaView I am wondering if the following is possible.

I have time-varying data, a set of vtk volumes. I have no problems to 
animate it over time.
On the same screen I would also like to have a 2D plot showing some 
physical parameter over time.
The point is that I want current time to be somehow depicted on that 
plot. For instance at time t on the
2D plot there will be a line plotted for x=t and y=[0-inf].
