[Help] A bitcoin balance checker by day

[lueo]

Dear all,

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?

I think you'd be better off using http://blockexplorer.com/q/getreceivedbyaddress/1HEmzeuVEKxBQkEenysV1yM8oAddQ4o2TX

So wget http://blockexplorer.com/q/getreceivedbyaddress/1HEmzeuVEKxBQkEenysV1yM8oAddQ4o2TX each day (cron job ?) and append to a file.

Dear dogisland,

Thanks for your advice, but what I need to do is to make a chart from the transaction history in the same time, not to record the balance day by day.

here is a function that you can use:

I can add a callback function if you need to do it in javascript
