"Play" the data through time. i.e. add one month of data at a time to visualise how things are chan

It would be good to "play" my data through time.  The best example of doing this is from

Example of data "play"

I have a data histogram that I would like to add one month at a time from inception to visually see where values are landing.  

Build the histogram over time

The best way to do this would be to play the data rather than view it statically.  From a technical perspective I think this should not be too difficult

Thanks,

Bob
