How do I save a graph?

Currently, you can't. Take a screenshot and save it as an image. I will provide a way to save your logs and graphs soon.

There are a ton of other values, how can I see those?

Currently, you can't. I will provide a way of choosing the values you wan't to see soon.

Can I upload a log directly?

Currently, you can't. This is a deliberate choice to make the web a safer place. JavaScript-applications should not have direct acces to your computer, therefore I chose copy&paste.

Where do I find the log?

Look under \My Documents, there you should find files named like PowerLog_20100315232131.txt.

Technology

This project is currently purely client-based, i.e. it is written in JavaScript using jQuery and jqplot. I intend to implement a PHP and MySQL server back-end later on, depending of course on the usage of this tool. Yours and mine, that is.

That would allow user registration, storing of logs and graphs as well as tips about your battery usage like warnings about the dangers of your charging habits. Please give me feedback if you would like those features.
