Unfortunately BTC-E doesn't give you much historical data I believe via its API. When you first start using this tool you'll not have much data. Personally I found it best just to leave it running 24/7 for a while so you gather some.

I could be wrong about the above though, in which case a suggested improvement to the app would be to grab more data as part of the initial scrape.

As an aside, I had mine offline for a while so had a big hole in the data feed. To get around this (and start afresh) I had to delete both LTC_USD.csv and LTCU_log.txt. I suspect the latter (which only contains a number) allows the app to know where it got to.
