A graph has stopped showing data at 10,000,000

[cbrabin]

We have a graph that basically counts rows in a db. Once the count got to 10,000,000 it stopped plotting data.
I can see the script running and returning a value greater than 10mil.
I found that the data template had a max limit of 9,999,999. So I changed this and still there is no data coming in to the graph.
Is there anything else I need to change or look at.
I am still quite new to cacti so I am presuming that its something I have not done rather than a fault.

Thanks

I suppose that's due to a data source MAXing out. Please see 2nd link of my sig, search for the data source max entry
