data visualization - graph

[Kasper Jepsen]

Hi,

I am looking for a solution to graph charts from real time measurements on the web like:
http://pvoutput.org/intraday.jsp?id=16919&sid=14707&gs=1&dxa=1&dt=20150715

I have some solar systems i like to save data into an sql database - and then i like to have some web service where i can select which data to see and compare and zoom in/ out etc.

I like to do it in Python - but maybe some else also?

Also i like as much as possible in some library / packages..

Any one who has experience?

best regards
