Imaging you have graphs for a number of countries, all expressed in barrels per day. For each of the graphs, chop off the bottom piece of the graph, that shows no variability. For example,

In other words, subtract an amount equal to the lowest production during the period shown on the graph for each country. In the graph above, it occurs when hurricanes interrupt production. That is the baseline production.

Then produce a graph by adding up the tops of the various graphs. The band width shows how a particular country's production has increased or decreased. So what a person is looking for is changes in band widths--narrower widths mean less production for that particular country.

Matt has some groupings of countries he uses. All countries that he think peaked in 2005, for example. The bigger countries are shown separately, though.

Perfect.

Now that you've pointed it out, it's crystal clear!

Thanks.
