charts altcoin prices - good data provider, with freely adjustable charts?

[drakoin]

I would like to study time series of coins ...
especially when they came newly onto an exchange like cryptsy.

Every exchange has less or more primitive charts,
but often those hide more than they show.

The spikes, or the age of the coin make it quite difficult.


Anyone got a good source for altcoin price charts?

* ideally, a start date and an end date for the chart can be chosen freely
* with a freer time scale than 6H 1D 1W 1M All
* with a freely choosable Y-axis

I like the technology at tradingview, but not their dataset.
They only have very few altcoins like ppc, nvc, ltc


Thx
