Could you suggest me markets monitor for Linux? (newbie)

[geco-geronimo]

Hello everybody!
I'd need some suggestion: do you know some tools for Linux that I could use to monitor more exchanges at the same time? For instance, I would like to have in the same chart the BTC/USD ratio in Kraken, Bittrex anc CEX.io, possibly crating more charts with different variables (BTC/ETH or other altcoins). Besides, I would like to have the possibility to adjust the time span showed by the chart.
Thank you very much for your suggestion!
