Could someone help to extract the "real time" hashrate history data plot?

I’m just considering a ppcoin hashrate — time plot similar to the page of .

BTW, PPCoin retargets every block, and the retarget is based on a week moving average window, so the “real time” block difficulty/ hashrate for each block is not really real time. I think a smaller averaging window difficulty/ hashrate data can also be extracted from the existing blockchain. In such a case, we can spot some important information of the network hashrate and the activities of ppcoin users.

Thank you.

You should be also spying on pool success rates (luck percentage) to easily explain the mass fluctuation of PPCoin users. You can calculate it as hasrhate vs. blocks found.
