I'd like to write a tool in python that can collect the balance of an BTC addr by day. So that I can display the progress in a line graph.
I would like to ask help for:
1. How do I collect day-by-day balance from blockexplore? For example, I need a function that can return the following information to me:
(Original information from http://blockexplorer.com/address/1HEmzeuVEKxBQkEenysV1yM8oAddQ4o2TX
Date, Time, balance
2010-10-9, 09:10, 34.9
2010-10-10, 09:15, 36.9
2. How do I convert them into a rrd file?
I've searched on the net and I found a tool called pyrrd, have you tried to use it to convert data into a rrd file?
