So, I finally did some basic Google Visualization stuff. On the sidebar, for my energy usage, you can now see a link for usage history. This will open a new window that shows daily KWH usage for my house. It’s an annotated timeline, though I’m not currently doing annotations.
It’s pretty simple, about 40 lines total, of which, 15 or so are php. Nothing too special. You’ll also find a link on that page to the “RAW” data, in all it’s “glory”.
More to post later, but for now, it’s all I got.
Here’s the page I used for how to structure the java output from php to make it work: http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html
