Has anyone calculated a graph of the inflation rate over time? (The derivative of the total BTC).

I have seen the long term calculated Bitcoin generation graph that maxes out at 21M. That is not what I want.

Or alternatively, is there a table of approximate inflation, e.g.:

Date  StartBTC  EndBTC     Inflation
2009    0            1M             Infinite
2010    1M          3.8M         380%
2011    3.8M        6.5M        102%
....
2050    21.45M       21.46M       .02%

Is there such a table or graph? I can probably calculate out the numbers myself but is it already done somewhere?

The inflation rate reflects the rise of general prices, not the number of existing bitcoins. That's something completly different.

(I changed the word from "inflation" to BTC Increase rate - only to avoid a pointless argument over whether inflation is a monetary phenomena or a pricing phenomena. I am well aware of that debate in economics, but it should be clear in this context what I meant: monetary inflation)

Answering my own question, here is the table:

 Year New BTCs/yr Start BTCs End BTCs BTC Increase 2009 2625000 0 2625000 infinite 2010 2625000 2625000 5250000 100.0% 2011 2625000 5250000 7875000 50.0% 2012 2625000 7875000 10500000 33.3% 2013 1312500 10500000 11812500 12.5% 2014 1312500 11812500 13125000 11.1% 2015 1312500 13125000 14437500 10.0% 2016 1312500 14437500 15750000 9.1% 2017 656250 15750000 16406250 4.2% 2018 656250 16406250 17062500 4.0% 2019 656250 17062500 17718750 3.8% 2020 656250 17718750 18375000 3.7% 2021 328125 18375000 18703125 1.8% 2022 328125 18703125 19031250 1.8% 2023 328125 19031250 19359375 1.7% 2024 328125 19359375 19687500 1.7% 2025 164062.5 19687500 19851562.5 0.8% 2026 164062.5 19851562.5 20015625 0.8% 2027 164062.5 20015625 20179687.5 0.8% 2028 164062.5 20179687.5 20343750 0.8% 2029 82031.25 20343750 20425781.25 0.4% 2030 82031.25 20425781.25 20507812.5 0.4% 2031 82031.25 20507812.5 20589843.75 0.4% 2032 82031.25 20589843.75 20671875 0.4% 2033 41015.625 20671875 20712890.63 0.2%

Hope this table format comes out right.
It looks like another few years until Bitcoin generation rate is in the same reported range for existing "printed" currencies.
Demand may remain strong, however, so the above says nothing about what relative value it will have.

You can go to
http://blockexplorer.com/q/totalbc
and get the current total.
Then while bitcoin generates 50 coin per block (until 2013, right?)
rate = 100% * 50.0 * 6*24*365 / totalbc
As I was writing this, totalbc was 7207850.
rate = 100% * 50.0 * 6*24*365 / 7207850.0 = 36.46%
