|home energy usage - new shiny graphs!
||[Jul. 6th, 2010|11:09 am]
I've been wanting to play around with Tableau Public, so I decided to revamp my home energy usage graph.
Anyway, the new version is here, and I think it does a good job of showing the difference that having someone upstairs during the day makes, as well as the new A/C unit we bought a few months ago. I used a quadratic fit which seems to fit the data much better than the linear one I used before (you can mouseover the trend lines to see the equations!). Now I just need to wait to get some more data points!
You can click on points in either graph to see the corresponding one in the other, and Tableau makes it easy to download the raw data I used. If you select "True" for "Upstairs during day?" you can really see the effect of the new A/C. (green points vs. orange)
Thanks to Robert Morton for his help in getting it up and running!
