On that note, can a few people take a look at this:
http://wafflepool.com/stats2And let me know if the first two graphs are an easier method of explaining that data?
The trouble with comparing pool BTC Earned and BTC/MH on the same graph is that while they are indeed related, their relationship is only loosely connected and also depends upon such factors as efficiency of profitability algorithm, overall network difficulty across all coins, and of course, luck, and likely others such as server maintenance issues, network latency, and so on. So there is really no reason to compare the two together, as it will only lead to confusion and misinterpretation by many.
But people do like charts to look at, as it somehow makes them feel more comfortable. Keep your charts clean and allow people to draw their own conclusions even if they choose the wrong ones. A classic example: oh, the pool has been very unlucky over the last 24 hours, so that means it will be very lucky over the next 24. This is complete garbage of course, a simplistic perversion of regression to the mean, but it makes some happy to think that.
Given that overall network difficulty for the most profitable coins is most likely to rise across the board while they are still profitable, that graph only makes it look like there is something wrong, as it fails to quantify those other contributory variables listed above, but most notably aggregate network difficulty.
And for the most part, people usually only care about their own personal statistics. With the exception of some sort of pool luck calculation, which is largely useless in predicting the future, but people like to have an idea of where they've been so they can imagine something to look forward to.
