@paul - just a thought on presentation - for the graph Bible Studies : Baptisms you have tiny red bars representing baptisms because those numbers are >300k per annum whereas Studies are on the 6m+ range
In Excel you can plot a 2nd y-axis on a different scale - in this case maybe 0 - 1m for the baptisms would make the point clearer.
Send me the excel file and I can do it for you if u like.
