I'm mining in the p2pool anomalypool. The graph in the p2pool site shows certain payments but do not see them in my wallet. About 25 minutes ago, the graph shows around 0.04 CGA but I did not receive this in my wallet. 15 minutes ago, graph shows around 0.03 CGA and I received 0.029 CGA. 10 minutes ago, graph shows around 0.08 CGA and have not received anything in my wallet. Can someone please explain what is happening here. I don't want to get confused more.

Edit: About a minute ago, I see 0.06 CGA and nothing received in my wallet. Are these orphans?

Edit 2: Can someone explain the two graphs listed for each miner? I understand the first graph is the miner's hash rate. What is the 2nd graph for?
