Yes, the block should be generated every 10 minutes but it is not. I want to build next difficulty prediction based on time value that will be required to generate next 2016 blocks after difficulty change. I want to extrapolate current block count into future and estimate this time.

Hello, guys!

I'm trying to find historical hourly or daily data of blockchain height (blocks count). I only found the number of blocks mined last 24h on http://www.bitcoinwatch.com/ but can't find historical data charts like this https://blockchain.info/charts. Is anybody know any sites or API with that data?  Thanks
