Added a power consumption graph to the daily chart page. The chart scales will need to be modified so that they match. I have a web site that hosts a complete set of power usage charts here. These pages are optimised for display on an iPhone, but also work well in a full browser. A full explanation of how the charts were created is here (PDF).

These web pages were hand crafted using Coda, on a Mac. The pages should be HTML 5 compliant, with half decent CSS 3. You will need a decent browser.
The logo at the top of the page was created with Pixelmator. As you can tell I am no artist, but I am happy with my efforts.
The weather station is a WH1080 from Fine Offset, mine came from Clas Ohlson. In November 2010 it was on sale and only cost £45.
The data is collected on a small Linux server running PyWWS. This is a Python based application that takes the information from the USB connected display module. The same application then stores and processes the data. It also creates the charts and the tables.
The charts are created by PyWWS using gnuplot, and finally uploaded to this web site.
The charts are in fact SVG files. Much better than the rather the nasty looking PNG the application creates by default. Not only do they look a lot better, but they obviously scale when viewed on small or large screens. However they are somewhat larger than PNG files. You will need a modern browser to see the images; such as a Webkit based browser (Safari or Chrome) or Firefox 4.
The weather station is located in Hersham, Surrey in the UK. The exact location is latitude N 51° 36' 23", longitude W 00° 40' 23" at an elevation of approximately 18m. Data has been recorded here since 22nd December 2010, some 515 days ago.
If you have any questions you can me here.

Next steps
A few thoughts on how the site may develop.
- Optimised pages for mobile devices, at least for the Apple iPhone and the iPad.
- Improvements to the graphs - rose charts need the legend moving to one side.
- Additional graphs and tables, high/low records?
